Wright’s Tire Rubber Modified Asphalt Cement (TRMAC™) Technology is an absorption process that completely digests and incorporates whole scrap ground tire rubber into asphalt cement.  The TRMAC™ system is manufactured within a terminal facility environment, which provides the ability to Quality Control the entire process and certify the end-products.  Wright’s laboratory facilities provide the structure to continually test, quality control and certify 24 hours a day, which assures excellent consistency in processing and in the final products manufactured.

The TRMAC™ process provides the building block for all of Wright’s Terminal Blended tire rubber modified asphalt products.  Wright uses recycled whole scrap ground tire rubber in the TRMAC™ process.

The products created with the TRMAC™ process are compatible with and are a plasticizer for additional polymer modifications.  Styrene-Butadiene-Styrene polymer (SBS) is used in some TRMAC™-based products to enhance the elastic recovery and ductility strengths of the finished product.  The SBS polymer in combination with the TRMAC™ process produces a finished product that adds greater adhesive strengths to roads and aggregate surfaces maintaining a tough bond and cohesive strength over time.  Products created with the TRMAC™ process exhibit excellent resistance to high temperature rutting and aging while still maintaining cold temperature flexibility.

The TRMAC™ process was developed to be performance-based, producing higher-quality products that last longer and provide superior performance. This process is the first step in producing Wright’s Terminal Blended tire rubber products.  The TRMAC™ is then blended into various finished tire rubber products which are used for pavement maintenance (high performance chip seals and surface sealers) and construction (high performance hot mix binders).
