Elaster BM-3a (PMB 35/80-55) bitumen is a polymer modified bitumed obtained by chemical crosslinking with elastomeric polymers that complies with EN 14023 specification. It has a minimum softening point of 55 ºC, high cohesion and it is storage stable. The adhesion promoter increases resistance of the asphalt mix and improves water sensitivity test results. This bitumen is suitable for improving the stability and resistance to plastic deformations of asphalt mixtures. It is suitable for most types of asphalt mixes, including open graded mixes like PA and BBTM while improving cohesion and deformation resistance.
