The B270 (Waldfischbach, Germany) test sections where the asphalt with B2Last® achieved similar properties to a typical PmB 25/55-55, while reducing mixing and laying temperature (Warm Mix). Picture courtesy of BASF

B2Last®: the new bitumen additive for enhanced asphalt durability

The principles and benefits of B2Last® were validated in the B270 test section where it was shown that similar properties to those obtained with conventional polymer-modified binders could be achieved, while allowing for a significant temperature reduction (Warm Mix)
