Polymer Modified Bitumen

Key Features

Mahavir Chemicals Polymer Modified Bitumen isn't just ideally suited for hot climates, but also satisfies the rising demands due to heavy vehicle and traffic volumes on today's roads and runways. Mahavir Chemicals Polymer Modified Bitumen is manufactured with a specially blended feed, making the binder homogenous and storage stable. It enhances the key properties of asphalt mixes, i.e. deformation resistance and fatigue life. These improvements are the result of three vital physical changes which the polymer makes in the conventional binder structure: reduced temperature susceptibility, increased stiffness modulus and enhanced elasticity .






  • Surface dressing

  • Wearing course

  • Stress absorbing membranes (crack sealing)

  • Stress absorbing membrane interlayer

  • Base course

  • Thin overlays



Advantages of Mahavir Chemicals PMB 40 over Conventional Bitumen
