Polymer modified Bitumen (PMB)


As asphalt is a temperature susceptible material, It gets softer at high temperatures and Stiffer at low temperatures, this behavior results into rutting in summers and cracking in winters. Polymer modification of asphalt is done to reduce its temperature susceptibility. The desired behavior of asphalt is such that it should resist both rutting and cracking due to temperature changes, to achieve this goal, polymer modification of asphalt was done The polymer used for the modification of asphalt is Elvaloy® RET which is a reactive elastomeric terpolymer with the chemical designation EGA (ethylene/glycidyl/acrylate) the first DuPont polymer specifically designed for modifying asphalt.
