The addition of polymers increases elasticity, strength, and temperature resistance, which helps reduce rutting, cracking, and pavement failure.

The softening point indicates the temperature at which bitumen begins to soften. A higher softening point means the pavement can withstand higher temperatures without deformation.

Viscosity determines how easily bitumen flows during mixing and paving operations. Proper viscosity ensures better coating of aggregates, improved bonding, and enhanced pavement durability.

Polymer Modified Bitumen is a type of bitumen that is enhanced by adding polymers to improve its elasticity, strength, and resistance to temperature variations. It is widely used in highways, airport runways, and heavy-duty pavements.
