I. INTRODUCTION
ADOT has approximately 550 lane miles of jointed portland cement concrete pavement under
its jurisdiction. Traffic patterns vary from 8,400 ADT on a rural four lane interstate highway to
117,000 ADT on an urban six lane freeway system. Truck traffic ranges from 36% on interstate rural
highways to 10% on urban freeways in Phoenix. 1
Climatic conditions in Arizona impact joint sealant performance dramatically. The average
low temperature in Arizona's high country (above 6,000 foot elevation) is 1 5 ' ~ during January while
the average high temperature is 8@F, in July. The average low temperature in the desert environment
(1,000 foot elevation) is 65'~ in January and the average high temperature is 115'F in July. Average
rainfall varies from 19 inches of precipitation near Flagstaff to 7 inches of precipitation in the Phoenix
area.
Not only does a joint sealant have to contend with large temperature variations in regard to
flow considerations, it must also contend with stresses associated with slab movement due to frost
heave and temperature changes. No one sealant may be capable of meeting the extreme climatic
conditions experienced on Arizona's highways.
The Arizona Department of Transportation installed a test section in July, 1986, to address the
performance of joint sealants in the Arizona high country under a joint resealing project. The test
section will be monitored for a period of four years. The Department does not currently have a
performance aiteria for joint sealants. Results of this study will be used to aid the Materials Section in
determining which types of joint sealants are appropriate for joint resealing projects in the high
elevation regions.
11. LOCATION OF TEST SECTION
An advertisement for bid, IR-17-2(104), was let March 28, 1986, to reseal 26 miles of plain
jointed portland cement concrete pavement on the southbound lanes of 1-17, south of Flagstaff
(Figure 1). The joint sealant selected for the resealing project was Superseal 444, a hot-pour material
produced by Superior Products. A copy of ADOT's joint sealant specifications for this project is
included in Appendix A.
The test section per change order #4 is located between MP 330.5 and 331.2. MP 330.5 is at
the crest of a hill and in the transition of a 0.052 feet per foot superelevation. The elevation of the test
section is approximately 6,700 feet.
The original project, I-17-2(35), was built in 1974. The eight inch thick, 24 foot wide slab, was
constructed with eight inches of portland cement concrete pavement over six inches of portland cement
treated base. Contraction joints were designed to be at 17, 15,13,15,17 foot spacings. Actual spacings
and current condition of the test section are documented in Appendix B. Joints are on a 6:l skew with
an original saw cut of 1/4 the pavement thickness (two inches). The original joint sealant material was
Superseal 444. (Figure 21)
111. DESCRIPTION OF SEALANTS
There were five joint sealants selected for the study: Allied-Koch 9005, Crafco Roadsaver 231,
Dow Corning 888,Superior Products Superseal 888, and W.R. Meadows SOF-SEAL. Dow Coming 888
and Superseal 888 are 100% silicone sealants. W.R. Meadows SOF-SEAL and AUied-Koch 9005 are
asphalt based materials and Roadsaver 231 is an asphalt-rubber based material.
Figure 1- Location of Test Section
The silicone products are placed at ambient temperature, while the asphalt and asphalt-rubber
products are placed at 360% to 380'~. A copy of each material description and specifications is
included in Appendix C. The silicones meet Federal specifications SS-5-00230C and SS-5-001543A
while Allied Koch meets ASTM D3405, Roadsaver 231 meets modified ASTM D3405, and SOF-SEAL
meets ASTM D3407 for low modulus sealants. A copy of Superseal 444's description and specification
is also included in Appendix C.
The estimated material wst, per 100 lineal feet of joint, for each product on this project is:

IV. CONSTRUCTION REPORT
The placement pattern for the five joint sealants was selected to minimize any biases and to be
statistically valid. A total of 200 joints were sealed in the test section, 40 joints for each material. The
sequence of placement was A, B, C, D, E, A, B, C, D, E, and so on, where A is Dow Corning 888, B is
Superseal 888, C is AUied-Koch 9005, D is Roadsaver 231, and E is W.R. Meadows SOF-SEAL. Four
of the products were placed in a two-day period: July 8, 1986, and July 9, 1986. The fifth product,
Superseal 888, was placed July 14 and July 25. The average high temperature for each days placement
was approximately 769,and the average low was approximately 48'~.
The placement of A, B, C, and E was performed by the contractor, Conseal of Layton, Utah.
Material D was placed by Robert Rutherford, a field representative of Crafco, using a Crafco EZ Pour
50 Melter. All joints were sawed to a depth of 2 inches and a 1/2 inch nominal width by the contractor.
Actual joint width was closer to 3/4 inches. All joints were sand blasted and air-blown by the
contractor. (Figure 3) The backer rod was Hercules XL, a 718 inch closed cell polyethalene material.
All joints utilized the same backer rod; however, different depths were used for different products. The
backer rod was placed with steel wheels set to the necessary depth. (Figure 4)
k DOW CORNING 888
The Dow Corning 888 silicone was placed in a two day period. On July 8, 40 joints in the
passing lane and 27 joints (beginning at MP 330.5) in the driving lane were placed. The remaining 13
joints were placed on July 9.
After the joints were prepared the backer rod was placed approximately 1/2 inch from the top
of the dab. The silicone was supplied in five gallon buckets and placed by an air driven pump. After
placement, it was immediately tooled with a rubber hose on the end of a broom stick. The tooling was
necessary to ensure that the sealant was below the surface of the joint. Figures 5,6, and 6 are photos of
typical silicone joint sealant placement. A four man crew was used to place the material: a driver, an
operator for the injection, a tooler, and a clean-up person.
No major problems were encountered during the Dow Corning placement. The technical
representative was satisfied that all joints were placed in the proper manner with the exception of the
fust three joints in the passing lane at MP 330.5. These joints still had residue of the previous sealant in
several locations. The technical representative stated that he could not guarantee adhesion in those
Figure 4- Placing Backer Rod
areas. The contractor's representative stated that based on his experience the sealant would hold. The
joints were, therefore, sealed with the silime in order to determine the effectiveness of the adhesion
to an improperly cleaned joint.
B. SUPERSEAL 888
Superior Products was unable to supply their material in time for the two-day project. The
Superseal 888 product was placed on the 14th of July in the passing lane and on the 25th of July in the
driving lane. The equipment and installation procedure was the same as for the Dow Corning 888.
Prior to placing the product, the pump had to be purged, so as not to contaminate the material with the
previous Dow Corning 888. Figures 5,6, and 7 are photos of typical silicone joint sealant placement.
Superior Products failed to provide a technical representative during the placement. They had
been given an opportunity to provide a representative. Frank Gauss, president of Superior Products,
stated that the contractor CON-SEAL, had extensive experience placing Superior Products 888 and
was confident that the material would be properly installed.
No problems occurred during the placement of Superseal 888. The product performed much
like the other silicone except that it did not tool as easily. The contractor had to make more passes over
the joint in order to make it neat and get it below the surface.
C. ALLIED-KOCH 9005
Allied-Koch 9005 is a low modulus, hot-pour asphalt based material placed at 365OF. Both the
driving lane joints and the passing lane joints were sealed on July 8, 1986. This was done in order to
clear the pot at the end of the day and use the same pot for the W.R. Meadows product the next day.
After preparing the joints the backer rod was placed 1-114 inches below the to& ' of the slab. The material was heated in a melting pot until the temperature reached 370' to 380 F. The crew
consisted of a driver and an applicator. Figures 8 and 9 are photos of typical hot-pour placement.
The AUied-Koch 9005 exhibited a great deal of flow on the ,052 foot per foot superelevated
horizontal curve. Also, a large number of bubbles were observed immediately after placement. It was
visually estimated that there were two to three bubbles per lineal inch.
D. CRAW20 ROADSAVER 231
Roadsaver 231 is a hot melt material which is heated to 380~-400~foFr placement. Three
joints in the passing lane (MP 331.2) were Fied on July 8th before an equipment failure stopped the
operation. The balance of the joints were sealed on the following day, July 9.
The placement of Crafco 231 was basically the same as the placement of the Allied-Koch. The
depth of the backer rod was 1-114 inches and the material was heated to 380°-4000~ and poured at
365'~. Two people were required for the Crafco operation: a driver for the vehicle, and an operator
for the pot. Figures 8 and 9 are photos of typical hot-pour placement.
The material did not exhi'b'i the same flow characteristics as the Allied-Koch 9005 and SOF-SEAL
materials. The Roadsaver 231 material appeared stiffer and, therefore, a more uniform depth of
sealant was evident in the superelevated portions of the curves. Air bubbles were present immediately
after placement of the sealant - approximately three bubbles per lineal inch.
The Roadsaver 231 was also placed in a transverse crack in the inside asphalt shoulder and in
the longitudinal joint for about six to eight feet at MP 331.4. Also, at MP 330.6, a longitudmal crack
extending through three panels in the passing lane was sealed with the Crafco product. It was estimated
that two applications of sealant would be required to fd the crack; however, only one application was
needed.
E. W.R MEADOWS SOFT-SEAL
W.R. Meadows sealtight SOF-SEAL is a low modulus, hot applied material placed at 380'~.
Both the driving lane and passing lane joints were sealed on July 9, 1986. The same melting pot was
used for both this product and the Allied Koch which had been placed the previous day. Before
heating, the pot was purged and the equipment cleaned out. The backer rod was placed at 1-1/4 inches
below the surface of the slab. The crew consisted of a driver and an applicator. Figures 8 and 9 are
photos of typical hot-pow placement.
The SOF-SEAL exhibited the same characteristics as the Allied-Koch 9005. It did not flow
quite as much, but it still tended to run on the elevated joints. It also bubbled much like the Allied-
Koch.
F. LONGITULXNAL JOINTS
The longitudmal joint between the driving lane and passing lane was fded with different
materials. On July 8, the contractor placed approximately 340 feet of Allied-Koch sealant in the
longitudinal joint from station 6938+80 to 6942+00. On July 9, Crafco placed their product from
station 6927+10 to 6938+80. On the same day, W.R. Meadows SOF-SEAL was placed from station
6944+88 to 6945+60.
On July 14, the cantractor placed the last of the Dow Corning 888. From station 6944+00 to
approximately 6944+80, Superior Products 888 was placed from station 6945+60 to 6946+00. The
remainder of the longitudinal joints were fded with Superior 444: station 6926+50 to 6927+10 and
station 6946+ 00 to 6956 + 50.

DESCRIPTION
Dow Corningo 888 silicone
highway joint sealant is a one-part
silicone material that readily
extrudes over a wide temperature
range and cures to produce a
durable, flexible, low-modulus
silicone rubber highway joint seal.
Because of its low modulus
characteristics and good extension/
compression recovery (+I00
oercentl-50 Dercent of oria"inal .ioint
width), ~ o w ' c o r n i n88~8 silicone
highway joint sealant gives
outstanding performance in
highway joints in which extreme
movement occurs.
Hia-hwav. con crete contraction1
expansion joints are generally
sealed to prevent concrete "slab
growth" and/or "blow-up," erosion
of sub-base, or corrosion of metal
tie bars embedded in the concrete,
resulting from incompressibles (dirt
and stones), water and deicing
chemicals entering the joints at the
joint surface.
Dow Corning 888 silicone highway
joint sealant features:
Ease of application - one-part.
ready to use as supplied: no mixing
required; dispensed directly from
bulk container into joint with air-powered
pump.
All-temperature gunnability -
consistency is relatively unchanged
over normal installation
temperature range.
Unprimed adhesion - primer is
not required for bonding to
concrete: surface must be clean,
dry, and frost-free.
Seals irregular surfaces - can be
used to seal joints where spalls
have occurred, provided adequate

contact is made between sealant
and substrate.
High movement capability - the
sealant will perform in a continuous
joint movement of +I00 percent and
-50 percent. In new construction, it
will take the 25-percent movement
of each of 2 or 3 slab lengths
working in unison before all the
"shrink or contraction cracks
occur.
Low modulus - the sealant
stretches 100 percent in the joint
with very little force. This places
very little strain on the bond line or
joint wails. This, in turn, maximizes
the probability of a successful seal
with continuous joint movement.
Movement of highway joints caused
by temperature, traffic and faulting
requires a sealant that does not
strongly resist stress andlor shear.
Fully elastic - the sealant can be
stretched to 100 percent or
compressed 50 percent of the bond
width and held there. When
released, it will recover 95 percent
or greater of the original dimension,
This extension and/or compression
can be repeated many times and
the sealant will resume its original
shape without splits or cracks.
Thus, when properly installed in a
highway contraction joint, it does
not "pump" out of the joint during
compression or split or crack
during extension.
Resilient - once cured, the
sealant rejects or prevents stones
and other noncompressibles from
entering the joint by "squeezing"
them out as soon as force pushing
these noncompressibles into the
sealant is removed.
Good weatherability - a 100-
percent silicone rubber that is
virtually unaffected by sunlight,
rain, snow, ozone, or temperature
extremes.
Fast cure -typically, the sealant
will have a tack-free surface in one
hour or less. With this fast cure and
recessed joint design, the road can
be opened almost immediately after
sealing in most applications.
Long-life reliability - under
normal conditions, cured sealant
stays rubbery from -80 to 300 F
(-56 to 149 C) without tearing,
cracking, or becoming brittle.
Compliance with performance
requirements - meets and exceeds
both Federal Specifications
TT-S-001543A Class A (one-part
silicone sealants) and TT-S-00230C
Class A (one-component sealants).
Also meets Canadian Specification
19GP9 Type I.
USES
Dow Corning 888 silicone highway
joint sealant is especially effective
for sealing transverse contraction
and expansion joints, longitudal.
center line and shoulder joints.
These concrete expansion1
contraction joints can be on a
roadway or a bridge. It can be used
as the original sealant in new
concrete construction or as a
remedial or repair sealant in old
construction.
In new construction. Dow Corning
888 silicone highway joint sealant
provides the extra insurance
needed if all the "shrink" or
contraction cracks do not occur
during the initial "weakening" step.
Thus, two or three concrete lengths
will act in unison, stressing a
sealant two or three times the
design dimensions or movement.
For use in repair or remedial
applications where other joint
sealing materials have failed
because of excessive movement or
poor weatherability, Dow Corning
888 silicone highway joint sealant
can be used to seal irregularly
shaped andlor spalled joints.
Thus, the joints do not need
reforming before sealing. These
joints should be dry and free of all
old sealing compounds.
Limitations
Dow Corning 888 silicone highway
joint sealant is not recommended
for continuous water immersion. It
should not be applied in totally
confined spaces where the sealant
is not exposed to atmospheric
moisture. The sealant bead should
be recessed below the highway
surface to minimize abrasion from
traffic and snow removal
equipment. The sealant should
never be applied to wet or damp
concrete or installed during
inclement weather.
The adhesion to joints that are
formed with noncement-based
products should be checked before
performing full-scale sealing.
HOW TO USE
Low-modulus Dow Corning 888
silicone highway joint seaiant easily
withstands extreme joint movement
when properly applied. The sealant
will withstand 100-percent

extension and 50-percent com-pression
of the original joint width.
But the recommended joint
movement design is for ?25 percent
(50 percent total) and not at the
sealant limits. This difference
provides the insurance for
successful seal when job site joint
widths are different than designed
widths. Therefore, the joint design
dimensions should be less than the
ultimate sealant capability.
A thin bead of silicone sealant will
accommodate more movement than
a thick bead. Dow Corning 888
silicone highway joint sealant
should be no thicker than 112 inch
(12.7mm) and no thinner than 114
inch (6.4mm). Within these limits,
the sealant width-to-depth ratio
should be 2:l. In all cases, it is
recommended that the sealant be
recessed below the road surface at
least 114 inch with 112-inch recess
being acceptable in wider joints
(see Table I).
Dow Corning 888 silicone highway
joint sealant is a nonsag sealant,
which allows its use in vertical curb
joints as well as horizontal joints.
Being a nonself-leveling sealant, it
must be "tooled" to insure good
contact and adhesion. An expanded
closed cell polyethylene foam aids
in sealant tooling, controlling
sealant depth and providing a
recessed nonbonding tooling
surface. In new construction where
the joint is a new cut, a shallow cut
is recommended where the backer
rod is placed on the "shelf" or
bottom of the joint (see Figure 1).
The recommended depths are
shown in Table I. This design
provides a firm support for sealant
tooling, making the sealant easier
to install, and provides more
insurance of good sealantlconcrete
contact. The shallow cut also saves
blades and time and is recom-mended
when the roadway will see
foot traffic, as in urban areas.
In repair work where previous
sealing materials have been of a
joint filling sealing type or the joint
is not broadened by sawing, the
standard joint design is advocated
where the backer rod is slightly
above the shelf. Enough space
between the bottom of the backer
rod and the shelf should be
provided for possible "pumping" of
old joint sealing - filling from the
bottom of the joint. It is recom-mended
that care be given to
selection of the proper oversized
backer. SO that a firm tooling
support is obtained (generally 114
inch larger than the jolnt works
quite well).
The Dow Corning 888 silicone
highway joint sealant is part of a
system which must include the
proper backer rod and proper
installation procedures. The backer
rod must be expanded closed cell
polyethylene foam. Several other
back-up materials (paper rope and
open cell foam) are available, but
have proven to be unacceptable.
There are several manufacturers of
closed cell polyethylene foam and
any may be used.
INSTALLATION
When using Dow Corning 888
silicone highway joint sealant, the
following procedure is recom-mended:
1. Clean all joints of contaminants
and impurities to the depth at
which the sealant and backer rod
are to be installed, by grinding, saw
cutting, blast cleaning (sand or
water), mechanical abrading or a
combination of these methods. This
will provide a sound, clean. and
frost-free surface for sealant
application.
2. Blow out dust, loose particles
and other debris from joints with
oil-free compressed air.' Surfaces
must be clean, dry, frost-free and
dust-free.
3. Install expanded closed cell
polyethylene foam rod back-up
material in joints. This material
permits application of a thin bead
and acts as a bond breaker, which
allows the silicone sealant to
stretch freely with the joint
movement (refer to Table I).
4. Apply Dow Corning 888 silicone
highway joint sealant in a con-tinuous
operation to properly fill
and seal the joint width. For
maximum performance, the sealant
should be applied above
40 F (4.4 C).
5. Using a blunt instrument, tool
the joint so that it is slightly
concave and approximately 1/4
inch below the roadway surface.
Tooling should be done before a
"skin" forms, usually within 10
minutes of application. Do not use
a soap or oil as a tooling aid (see
Figure 1).

SUPERSEAL 888
JOINT PREPARATION: Joints must be cleaned of all contaminants and impurities to the depth at
which the sealant and backer rod are to be installed, by saw cutting, grinding, water or sand blasting,
mechanical abrading or any combination of these methods to provide a sound, clean, dust and frost-free
surface for sealant application. Existing joints must be freeof all previous sealant residue. Loose part-icles
and other debris must be blown out with oii-free compressed air, leaving joint surfaces clean dry,
frost-free and dust-free.
APPLICATION: Install a dry back-up materiai (not impregnated with any wax, oil or solvent). Sealant
Should not be installed where it will adhere to the substrate on three sides. if a moveable backer materiai
(polyurethane foam or expanded polyethylene foam rod) Is not used, a bond breaker tape of polyethylene
should be applied in the bottom of the joint to prevent three-sided bond as shown below. Superseai
888 Silicone highway Sealant may be applied directly from the container without mixing, heating or
other preparation at outdoor temperatures as low as O'F (- 18"C), or even lower if the joint surfaces can
be kept completely dry and frost-free. The material is gunnable In high temperatures of + 10O0F (+ 38°C)
or greater. The joints should be properly designed in relation to field conditions, particularly consider-ing
the movement related to the thermal expansion and contraction of the substrate materials. The
desirable joint width may be determined by calculating the maximum change in the joint width between
high and low temperatures encounted. The depth of the sealant in the joint should not be less than
118" and not more than 318". It should be as nearly as possible equal to onehalf the normal width of the
unexpanded joint. Tool joint so that it is slightly concave and approximately 118" below the road sur-face.
Tooling should be done before a skin forms, usually 10 minutes after the installation of sealant in
the joint. Do not use soap, oil or waxes as a tooling aid.
BACKER ROD SIZE RECOMMENDATION: Joint width = Backer rod diameter as follows:
5116" = 318" - 318" = 112" - 112" = 518" - 314' = 718" - 1" = 1-118"
INSTALLATION REQUIREMENTS
Joints shall have proper shape factor depending on spacing and ambient temperature, be throughly
cleaned by sand or water blasting, bondbreaker, and installed with recommended application equipment
into clean, dry joint, at a depth no greater than one half the width of the unxpanded joint and a minimum
of 118" recessed below the pavement surface.

USE RECOMMENDATIONS: Superseal 888 Silicone Highway Sealant is well suited for use in sealing
transverse expansion and contraction joints and longitudinal joints in portland concrete cement pave-ments
where excellent movement and weatherability is essential.
USE LIMITATIONS: Superseal 888 Silicone Highway Sealant is not recommended for use in appli-cations
where hydrostatic pressure is present. It should not be applied in totally confined spaces where
the sealant is not exposed to atmospheric moisture. The sealant bead should be recessed below the
pavement surface to minimize abrasion from traffic and other road equipment wear. It should not be
applied on surfaces containing oil, solvent or other petroleum derivatives. When special coatings or
sealers have been applied to a substrate material, pre-application tests should be made of the adhesion
of Superseal 888 Silicone Highway Sealant to the special coating.
PACKAGING: Superseal 888 is available in 5gal. pails (4.5gal) and 55gal. dmms (45gal) with plastic
liners.
STORAGE AND SHELF LIFE: Stored in original unopened containers at or below 90°F (32°C) Superseal
888 has a shelf life of 12 months. (Shelf life may decrease 50% if material is stored at temperatures over
100°F andlor humidity over 100%).
PRECAUTION: During cure the product may irritate the eyes. Avoid contact with the eyes. In case of
contact with the eyes, immediately flush eyes with water for at least 15 minutes and consult a physician.
Wearers of contact lenses should be certain that all silicone is removed from the hands before touching
the lenses. Contact lenses can absorb the silicone and cause damage or discomfort to the eyes. The

SEALTIGHT SOF-SEAL is a premium
quality, hot-applied, single-compo-nent,
low-modulus sealant that per-forms
equally well in either Portland
Cement or Asphaltic Cement pave-ments.
As the name implies, it is an
entirely new "softer-sealer" with
low-modulus properties that permit
high elongation at relatively low
stresses, particularly at low tempera-tures.
In a typical joint sealer con-figuration.
SOF-SEAL is capable of
300% extension at -20°F at less
force requirement than any other hot
or cold-applied sealer. SOF-SEAL
was specifically developed to provide
an improved, all purpose sealant for
general usage and preventative main-tenance
service on all types of large
scale crack and joint sealing projects.
SOF-SEAL is composed of a com-bination
of polymeric compounds to
produce a softer, highly flexible
sealant for both random cracks and
joints In addition to low-modulus, its
qualities include excellent elongation,
high resiliency, tenacious bonding
power and exceptional longevity.
SOF-SEAL remains pliable in the joint
for years . . . even in cold weather
and under repeated freezelthaw
cycles. It does not become brittle and
crack out in the winter . . . will not
flow in warm weather.

ADVANTAGES
Reliable performance-SOF-SEAL is consistent and doesn't change, even
during cold weather or after repeated freeze-thaw cycles.
' Remains pliable in the joint for years . . . a superb preventive maintenance
factor.
Low modulus sealant-SOF-SEAL has low stress development, over a wide
range of temperatures, to effectively accommodate joint movement.
Field-tested-SOF-SEAL provides exceptional elongation and longevity. high
resiliency and tenacious bonding power.

PRODUCT EVALUATION 86-18
JOINT SEALANT STUDY
PROBLEM STATEMENT
ADOT has approximately 550 lane miles of jointed portland cement concrete pavement under
its jurisdiction. The current practice is to saw and seal the joints at the time of construction and reseal
the joints under a rehabilitation project. ADOT does not specify a performance criteria for joint
sealants. Since the performance life of dierent joint sealants varies considerably a research project
should be initiated to ascertain true benefits of the different sealants.*
The problem is complicated even more because sealants perform differently in the high
country. ADOT has not performed an evaluation of joint sealants in the colder regions.
OBJECTIVES
The objective of this study is to compare the overall performance of different types of joint
sealants in the higher elevations. The study is meant to aid the Department in developing performance
criteria. Ease of placement, as well as long term performance, will be studied.
The workplan will be as follows:
1) Select joint sealants to be evaluated and locate vendors that are willing to participate in
a project.
2) Develop evaluation uiteria for joint sealants.
3) Construct a test section in the high country utilizing different joint sealants.
4) Observe installation methods and practices.
5) Perform semi- annual inspections during the summer and winter, for a period of four
years.
6) Take cores after one, three, and four years.
A construction report will be written within 90 days after the completion of the sealant
installation and a fial report will be written within 90 days after the four year evaluation period.
