硬质沥青混合料的路用性能
Hard Asphalt Mixture Performance in Road Pavement
摘要
Abstract
In order to improve asphalt pavement performance in high temperature,more hard-grade asphalt is used in highway engineering.The performance of hard-grade asphalt (AH-30) is analyzed,by the component design of asphalt mixture using hard-grade asphalt,heavy duty road asphalt and SBS modified asphalt.The pavement performance of hard-grade asphalt mixture,heavy duty road asphalt mixture and SBS modified asphalt mixture are evaluated.The results show that the optimum asphalt content of hard-grade asphalt mixture is higher than heavy duty road asphalt mixture.Hard-grade asphalt mixture with high temperature stability and moisture susceptibility can be used in asphalt middle course to reduce the rut induced by high temperature and heavy loading.关键词
