Production Process for PMA Manufacturing with Elvaloy® RET
Modifying asphalt using Elvaloy® RET involves controlled feeding of the terpolymer (as free-flowing, meltable pellets) into a heated mixing tank. The product chemistry allows the RET (in melted form) to interlock with asphalt as the two ingredients flow together. Keeping the materials stirred gently, in a heated vessel, keeps the terpolymer locking itself into the asphalt, until the reaction is complete.
Production Guide for RET-Modified Binder
Before starting to produce PMA using RET and a new asphalt source, be sure to pretest the asphalt's reaction with RET in a lab, and assure that you have proper mixing capability.
