摘要
沥青碎石基层施工时容易出现粗集料离析、渗水过大和难以压实等情况。结合实体工程研究,提出合理的配合比设计、摊铺和碾压技术,可有效地避免粗集料离析,降低渗水系数,提高压实度,从而保证施工质量和进度。
Some instances like coarse aggregate isolation, too much water percolation and difficult compaction are inclined to occur in asphalt treat base construction. Combining with the practical engineering, the rational mix proportion design, spreading technology and roller compaction technology are proposed, which can effectively avoid and advance the degree of compaction, coarse aggregate isolation, depress water percolation coefficient thus the construction quality and schedule can be ensured.
