摘要
为了研究建筑垃圾再生骨料用于沥青混凝土的可行性,选取0-5mm、5-10mm、10-15mm三档再生骨料及与同规格新集料为研究对象,采用表观相对密度、常温压碎值、高温压碎值、洛杉矶磨耗值、吸水率进行表征。结果表明:再生骨料相比新集料,表观密度降低,吸水率、高低温压碎值及洛杉矶磨耗值均增大。
In order to study the feasibility of recycled aggregate from construction waste to be used in asphalt concrete, 0-5 mm, 5-10 mm, 10-15 mm recycled aggregate and new aggregate of the same specifications are selected as the research objects, and the apparent relative density, normal temperature crushing value, high temperature crushing value, Los Angeles abrasion value and water absorption rate are used for characterization. The results show that the water absorption rate, high temperature crushing value and Los Angeles abrasion value of recycled aggregate are all increased, and its apparent relative density is reduced.
