ADVANTAGES

Advantages of Polymer Modified Bitumen

Less rutting and fatigue cracking

due to increased elasticity.

Improved durability

since PMB is less prone to aging, oxidation and UV radiation.

Lower temperature sensitivity

which means PMB will not go soft in heat, will not crack in cold and hence will work in variety of climates.

Increased adhesion

which means better bonding with other construction materials and, as a result, enhanced overall durability of the structure.

Enhanced water resistance

which means PMB is less prone to water damage and is excellent for waterproofing.

High Skid Resistance

which contributes to safer high-traffic roads.
