Abstract: Organic rectorite (OREC) can significantly improve the resistance of asphalt to deformation and aging, but it tends to cause low-temperature cracking. To solve this defect, a novel idea that develops an OREC and polyurethane ...

Abstract: This study investigated the modification mechanism of polyurethane (PU) on the high- and low-temperature properties of asphalt based on experimental and molecular dynamics (MD) simulations. PU-modified asphalt was prepared ...
