Polymer Modified Bitumen

Polymer modified bitumen (PMB) is bitumen (asphalt) combined with one or more polymer materials. This modification is done with the aim of enhancing the mechanical properties of the bitumen material.

Polymer modified bitumen is typically used on road pavements to withstand heavy-duty traffic and extreme weather conditions. This material is also used as a sealant in residential roofing applications. Our product range is designed for heavy traffic locations such as highways, main roads, airfields, roundabouts and bus lanes.

BitChem Polymer Modified Bitumen is manufactured strictly as per IS 15462 : 2019
