碾压式沥青混凝土心墙冬季施工试验研究

Experimental study on winter construction of roller compacted asphalt concrete core wall

沥青混凝土心墙因其众多优势逐渐应用在水利工程中,为研究碾压式沥青混凝土心墙在冬季特殊条件下施工,选取不同实验材料及设备、设置不同碾压遍数等试验条件,进行对比分析得出:沥青混凝土可在冬季进行施工且砾石含量在70%、初始碾压温度130～145℃时施工效果相对较好。

Asphalt concrete core wall is gradually applied in water conservancy projects due to its many advantages.In order to study the construction of roller compacted asphalt concrete core wall under special conditions in winter,different experimental materials and equipments are selected,and different rolling passes are set.The test conditions and comparative analysis show that the asphalt concrete can be constructed in winter and the gravel content is about 70%,and the initial rolling temperature is 130~145℃.
