摘要
本文研究了渗透型沥青路面养护剂对既有沥青路面路用性能的改善效果。以某既有BRT沥青路面为试验路段进行实际工程施工应用试验研究,对比有、无喷洒养护剂的沥青路面前后路用性能变化情况。试验研究表明:在既有沥青路面喷洒一定量的渗透型养护剂后,与未喷洒养护剂的沥青路面相比,沥青路面渗水能力明显降低,沥青混合料的粘结性能有较大的提高,抗滑性能变化不大,高温稳定性有明显提高。
The improvement results for aged asphalt pavement of an infiltration maintenance agent were studied in this paper.Based on the BRT asphalt pavement road section in Fujian province, the experiments in engineering construction application were conducted to compare the performance of asphalt pavement with or without the maintenance agent.The experimental results show that, compared with no spraying maintenance agent, spraying the ration of the infiltration maintenance agent in aged asphalt pavement can result in the dramatically decrease in permeability coefficient of asphalt pavement, greatly improvement in bonding properties of asphalt mixtures, little effect on the depth of pavement structure and significantly enhancement in stability at high temperatures.
