Abstract
AbstractTo enhance the performance of high-viscosity modified asphalt (HVMA), polyphosphoric acid (PPA) and North American rock asphalt (NA–RA) were incorporated into styrene-butadiene-styrene (SBS)/crumb rubber (CR) composite modified asphalt, resulting ...Practical ApplicationsThis study investigates the effects of polyphosphoric acid (PPA) and North American rock asphalt (NA–RA) on the performance of modified asphalt (SBS/CR composite modified asphalt). The experiments show that both PPA and NA–RA ...Alt-text for graphical abstract: The performance of SBS/CR composite modified high-viscosity asphalt (A0 & B0) was optimized using polyphosphoric acid (PPA) and North American rock asphalt (NA-RA), respectively, and their modification effects were ...
