The Preparation Technology and Performance Study of SBS and Rubber Powder Composite Modified Asphalt

Abstract:

Taking SBS and rubber powder as modifier, adopting the dosage of 4%, 5%, and 6% of SBS while 2%, 4%, 6% of rubber powder to prepare composite modified asphalt, studied the preparation technology of composite modified asphalt, analyzed the trend of ductility, penetration, softening point and elastic recovery. The results show a certain SBS dosage, with the increase of the rubber powder, ductility decrease while softening point and elastic recovery increase, penetration decrease first and then rise. It can provide reference for the preparation technology and performance study of composite modified asphalt.
