本文以选择使用石屑代替天然砂和用粉煤灰代替部分矿粉的沥青混凝土路面全部施工过程作为研究对象,经过整理分析从而得出沥青混凝土拌合料中用石屑代替天然砂子和用粉煤灰代替部分矿粉后,显著提高了沥青混凝土的高温稳定性、抗车辙能力,增加了沥青混凝土路面使用过程中的耐久性和安全性,节约了资金,提高了资源利用率,同时为今后修订《沥青路面施工及验收规范》提供一定的参考价值。
In this paper, the choice of the use of rock chips instead of natural sand and fly ash instead of part of the asphalt concrete pavement construction process as the research object, after finishing the analysis obtained asphalt concrete mix with natural sand instead of stone chips and flour Coal ash instead of part of the ore powder, significantly improve the high temperature stability of asphalt concrete, anti-rutting ability, increase the durability and safety of asphalt concrete pavement during use, saving money and improve resource utilization, and for future Amendment “Asphalt Pavement Construction and Acceptance Code” to provide some reference value.
