Modification of Paving Asphalts with an Elastoplastic
- 24 Downloads
BND 60/90 and BND 89/130 paving asphalts were modified by addition of DST-30 elastoplastic and petroleum plasticizers. Their performance at temperatures from -(32-35) to +(90-95)°C was examined in comparison with that of commercial unmodified asphalts, which are efficient at temperatures from -(23-27) to +(44-50)°C.
