Polymer Modified Bitumen (PMB)
High-Performance Pavement Engineering
Polymer Modified Bitumen (PMB) is a highly specialized binder created by blending base bitumen with polymers (such as Styrene-Butadiene-Styrene or SBS). This modification fundamentally changes the binder’s properties, significantly improving its elasticity, temperature susceptibility, and durability. PMB is the premium choice for high-stress applications that demand maximum pavement life and resistance to cracking and rutting.
Key Features & Applications :
Enhanced Performance
Reduces permanent deformation (rutting) in hot weather and increases resistance to fatigue cracking at low temperatures.
Elastic Recovery
The polymer network allows the binder to recover its original shape after strain, extending pavement life.
Primary Use
Airport runways, heavy-traffic highways, racing circuits, and bridge deck waterproofing.
Benefit
Superior performance across a wider temperature range, resulting in significantly reduced maintenance costs over the pavement’s lifespan.
