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.
