【摘要】 针对传统的非透水性路面的生态性缺陷,探讨透水性沥青路面在城市道路中的设计及应用。基于减小地表径流及蒸发降温等生态环境方面因素,设计透水性沥青混和料的目标空隙率及路面厚度;并对透水性沥青混和料的配合比设计进行研究,为透水性路面的设计及其推广应用提供借鉴。更多还原

【Abstract】 Aiming at the ecological defects of traditional densities graded pavement,the design and applieation of penetrated asphalt pavement in urban streets were discussed in this paper.Based on the goals of reducing surface runoff and lowering temperature through evaporation,targeting voidage of asphalt mixture and pavement thickness were discussed,and design of the mix ratio of penetrated asphalt mixture was also explored,which provided references for penetrated pavement design.更多还原
