Elaster BM-3b (PMB 45/80-60) adhesion promoter bitumen is a polymer modified bitumen obtained by chemical crosslinking with elastomeric polymers that complies with EN 14023 specification. It has a minimum softening point of 60 ºC, high cohesion and it is storage stable. The adhesion promoter increases the resistance resistance of the asphalt mix and improves water sensitivity test results. It is suitable for most types of asphalt mixes, including open graded mixes like PA and BBTM, and also SMA. This bitumen improves cohesion and deformation resistance and rutting in every case.
