摘要
为设计出既满足透水性能要求又满足相应承载力要求的路面,分别从路面结构组合形式和沥青混合料配合比两方面进行分析与探讨。从PAC路面结构形式方面,阐述排水型路面性能特点;从原材料选择要求上,说明PAC混合料对集料、沥青、矿粉的技术要求。在最佳沥青用量和空隙率已确定的条件下进行性能试验,结果表明:排水型路面结构组合形式适用于中型交通量道路;PAC-13混合料无论在透水性能还是在力学强度方面,均满足相应要求。
In order to meet the requirements of the water permeability and carrying capacity, the PAC pavement is analyzed from two aspects： the pavement structure and the mixing ratio of asphalt mixture. The performance characteristics of drainage pavement are illustrated from the aspect of PAC pavement structure, and technical requirements of PAC mixture on aggregates, asphalt and mineral powder of raw materials selection are described. Experiments are performed under the optimal asphalt consumption quantity and void percentage. The results show that the combination types of drainage pavement structure is suitable for medium traffic volume road, and PAC-13 mixture can meet the requirements in both the permeability and mechanical strength.
