RoadStar PMB 40 is manufactured according to IS 15462-2004, I.R.C 53- 2010 specifications which helps in building higher resistance to deformation at high temperature, provides improved Aging Resistance and Adhesion between Aggregate and Binder, Higher Fatigue Life of Mixes, Delay in Thermal / Reflective Cracking, Improved Temperature Susceptibility and Over all Extended Pavement Life.
RoadStar PMB 40 application provides increase in Softening Point and decrease in the Brittleness that ensures more protection against Hot Climatic Conditions.
