摘要
对不同等级、不同环境条件下的排水路面进行功能性养护的研究,得出:环境条件是影响其渗水性能衰减和恢复能力的重要因素。环境条件越差,排水路面渗水性能衰减速率越快,路面需要的养护频率越高。并设计了一种排水路面养护时机的判定方法。研究发现,排水路面养护时机是随路面渗水性能衰减而动态变化的。路面使用时间增加,渗水性能降低,养护频率应增大,且渗水性能较差的路面应采用更高的养护频率。同时,还给出了不同环境条件的排水路面每次养护适宜的清洗抽吸遍数。
In this paper,it was concluded that the environmental conditions are the important factors that affect the attenuation and recovery ability of the drainage pavement.The worse the environmental conditions were,the higher the maintenance frequency of the pavement was required.This paper designed a method to determine the maintenance time of the drainage pavement,and found that the drainage maintenance time changed dynamically with the attenuation of the pavement seepage performance.With the increase of the pavement service time,the maintenance frequency should increase and the pavement with poor water permeability should adopt higher maintenance frequency.
