| Abstract: | The Paper made a study on the road service performance of high-viscosity hard asphalt mixture by comparing the road service performance of high-viscosity hard asphalt mixture (AH-30),heavy duty road asphalt (AH-70) and SBS modified asphalt mixture on an all-round basis.The comparison shows that the high-viscosity hard asphalt has the basic character of high viscosity and low penetration;its mixture has the advantages of high strength,high modulus,satisfactory high-temperature stability,water stability and high fatigue resistance.It can be applied in the medium and lower base course of asphalt pavement in southern hot and humid area,and greatly improve the road performance and service life of asphalt pavement. |
