WDRA bitumen modifier pellets are devulcanized crumb rubber that has been blended with other polymers, stabilizers and additives, and granulated to lock the rubberized binder additives into a stabilized storage system.
WDRA has demonstrated similar or superior stability and durability than SBS modified asphalt – registering better performance in low temperature cracking resistance, anti-stripping, flexibility, fluidity and workability.
