冬季低温期碾压沥青混凝土心墙施工技术

Construction Technology for Roller Compacted Asphalt Concrete Core during Low Temperature Period in Winter

寒冷地区冬季由于气温低,采用常规施工技术不能进行土石坝的碾压沥青混凝土心墙施工,工程要停工5～6个月,从而延长了工程施工工期。应用冬季低温期碾压沥青混凝土心墙施工技术,能够保证在冬季低温期进行施工,提高了工程施工进度,降低了工程施工成本,进而缩短了工程建设时间。

In cold area,conventional construction technology is not suitable for roller compacted asphalt concrete core of earth and rockfill dam due to low ambient temperature.In these circumstances,construction must be stopped for 5 to 6 months and construction time delayed.Construction technology for roller compacted asphalt concrete core used during low temperature period in winter enables construction to be carried out in cold winter,then accelerates construction progress,reduces construction cost and shorten construction period.
