摘要
沥青心墙是碾压式沥青心墙大坝的渗控设施,其性能决定水库蓄水成功与否.当选定沥青混凝土的配合比后,需对其进行制定试件并进行试验测试,通过对试块进行马歇尔和劈裂抗拉、压缩和水稳定等试验,判断其强度、变形等多项综合性能.为拟选混凝土配合比提供科学数据支撑,并作为现场碾压沥青混凝土具体操作和质检把控的根据和依托.
Abstract
Asphalt core wall is a seepage control facility for roller compacted asphalt core wall dams,and its performance determines the success of reservoir water storage.After selecting the mix proportion of asphalt concrete,it is necessary to develop test specimens and conduct experimental tests on them.By conducting Marshall and splitting tensile,compressive,and water stability tests on the test block,its comprehensive properties such as strength and deformation are evaluated.It provides scientific data support for the selected concrete mix proportion and serves as the basis and support for the specific operation and quality control of on-site rolling asphalt concrete.
