摘　　要：介绍了国内外对废弃混凝土利用的几种有效途径.根据废弃混凝土再生骨料孔隙率大、比表面积大、具有一定抗压强度的特点,提出了在道路工程中应用的具体方法.该材料可直接用于道路的垫层和基层中,经简单处理后还可用作道路面层及路面砖的再生骨料.According to some researches at home and aboard about effective utilizations of waste concrete,it concluded that waste concrete recycled aggregate is big in porosity and specific surface area, and possesses definite compression strength. This paper studies the problems of how to make the best use of waste concrete in road engineering, and suggests that recycled aggregate can be used directly in bed course and base course, and also can be use in pavement and concrete brick after simple disposal.

关 键 词：废弃混凝土 再生骨料 道路工程
