摘　　要：排水路面铺装自 1990年在日本开始被采用以来 ,现已成为标准的路面之一。之所以能迅速的普及 ,是因为它既能提高雨天的交通安全 ,又能降低交通噪音改善道路周边的环境。但对于如何分析排水性混合料的强度问题 ,至今还没有更多的研究。为此 ,结合日本采用排水性路面铺装实例 ,介绍分析了排水性混合料强度的原理和利用车辙试验机在 60℃时反复行走同时进行透水试验 ,测定透水功能的变化过程 ,由此得出反复承受交通负荷引起的空隙崩溃现象也受沥青的Porous asphalt pavement in Japan was introduced in the beginning of the 1990's, and in consequence, it has come to stay as one of the standard work processes. The reason why this process has spread at such a rapid pace is that this pavement contributes to driving safety in rainy weather and to the improvement of the roadside environment by reducing traffic noise. However, research on how the strength of this porous asphalt mixture generates has not been conducted in detail. With this respect, the authors try to clarify the mechanism of strength generated by a porous asphalt mixture, and the changing process of the permeability function is also examined through the repeated tracking test at 60℃ (and the water permeability test by use of wheel tracking test apparatus. In consequence, the result shows that the clogging consolidation caused by the repeated traffic load is much more affected with the viscosity at 60℃ (of asphalt used and a percentage of air voids of the mixture.
