R-504 & R-504HS SBR Latex Compounds (Get Quote)
These latex compounds are
used to produce polymer modified and high quality SHRP PG grade asphalt
cements for hot-mix asphalt applications. Asphaltic pavements constructed
with Rub-R-Road R-504 latex compounds are tougher, more flexible and more
resistant to rutting, aging and embrittlement caused by low temperatures.
Thinner applications can therefore be made to furnish more durable, non-skid
pavements.
R-504 latex compounds are
unvulcanized virgin synthetic rubber in liquid latex form. They are designed
to be added at the contractor's hot-mix plant for polymer modified hot-mix
asphaltic pavements and anionic asphalt emulsions used for tack coats.
R-504 latex compounds are specially compounded for maximum dispersion in
asphalt when added in a pug mill or drum mixer to maximize the flexure
fatigue resistance of the pavement.

R-549 & R-563 SBR
Latex Compounds (Get Quote)
These latex compounds are
used to produce high performance polymer modified asphalt emulsions for
chip seal and slurry seal applications. Surface treatments constructed
with polymer modified asphalt emulsions retain aggregate better and are
more resistant to embrittlement and bleeding.
R-549 and R-563 latex compounds
are unvulcanized virgin synthetic rubber in liquid latex form. They are
specially compounded for rapid blending with asphalt emulsions in bituminous
pressure distributors without special equipment. These latex compounds
can also be utilized by the asphalt emulsion manufacturer during the asphalt
emulsification process.

R-570 Liquid SBR Polymer (Get Quote)
This polymer is used to produce
high quality polymer modified crack sealants. R-570 is specially designed
to mix rapidly with hot asphalt cement in tar kettles without special equipment.
Time required for pre-blended crack sealants to melt is eliminated. Overband
crack sealants containing polyester fibers can be polymer modified to provide
the extra flexibility required in cold winter weather. Crack sealants produced
with R-570 are tougher, more resistant to embrittlement and less sensitive
to temperature extremes.
R-570 Liquid SBR Polymer
is a virgin unvulcanized styrene butadiene synthetic rubber polymer.
