Study on the Aging Resistance of Polyurethane Precursor Modified Bitumen and its Mechanism

Study on the Aging Resistance of Polyurethane Precursor Modified Bitumen and its Mechanism

As an environmentally friendly alternative for the production of high-performance modified asphalt by chemical reactions, a liquid-state polyurethane-precursor-based reactive modifier (PRM) was developed and employed in the asphalt modification. In contrast to the traditional solid bitumen modifier,...
