空隙堵塞对透水沥青路面透水性能的影响研究
摘要
Abstract
Based on the structure and environmental particulate matter characteristics of typical drainage asphalt pavement in China,indoor simulation test methods were used to systematically analyze the anti-clogging performance of asphalt mixtures with different void characteristics to various graded particulate matter.The results showed that all test pieces showed rapid attenuation of water permeability coefficient in the early stage(<60 minutes),mainly due to the preferential clogging of surface pores by particulate matter;coarse particles of 1.18-2.36 mm have little impact in the later stage(＞100 minutes),because they mainly accumulate on the surface and maintain permeable channels;medium-sized particles of 0.3-1.18 mm show the most significant blocking effect,which can simultaneously form surface accumulation and internal retention;fine particles of less than 0.3 mm have the smallest impact on permeability because they are easy to be discharged with the water flow;mixed-graded particles cause serious deterioration in permeability at all time periods due to the collaborative filling effect of multiple particle sizes.关键词
