By studying the physical properties of the modified asphalt, it was found that it has good heat resistance, tensile properties, and adhesion properties. At the same time, the modified asphalt was mixed with stress-absorbing layer materials to prepare a mixture, and its road performance was tested.The test results show that HDPe-modified asphalt stress-absorbing layer mixtures have good road performance, and their bending fatigue performance, shear resistance, and durability are better than traditional asphalt stress-absorbing layer mixtures. Therefore, the application of HDPe-modified asphalt in stress-absorbing layer mixtures has broad prospects.【Keywords】HDPe; Binder; Modified Asphalt; Stress-absorbing layer mixture; Road performance
