摘要
碾压沥青混凝土施工在很大程度上受制于天气,恶劣气候地区全年适应沥青混凝土施工的天数非常有限,如何增加其有效施工期非常重要;在四川省南桠河冶勒水电站大坝工程,进行了沥青混合料摊铺层厚30cm、环境气温-6℃以上、日铺筑2层的研究和应用。这些非常规施工方法经过冶勒大坝沥青混凝土防渗心墙施工的实践,证实和验证了其施工质量的可靠性。本文对碾压沥青混凝土的非常规施工进行了介绍。
<Abstrcat>For construction of Yele Hydroelectric Project dam asphalt concrete wall,the asphalt concrete mix was laid in layers of 30cm thick under the ambient temperature above-6℃ and two layers were placed everyday.The hydroelectric project is located on the Nanya River in Sichuan Province.The unconventional practice for construction the dam asphalt concrete cut-off wall demonstrates satisfactory quality & reliability of the construction method.This paper recounts the unconventional construction procedure of the roller compacted asphalt concrete.
