Abstract: The waste concrete is broken into pieces, and the recycled aggregate is used for road engineering, and this method can achieve the effective utilization of civil resources. In this paper, the performance of re-cycled aggregate used for road use is reviewed, and some problems in the application of subgrade and pave-ment are summarized, and some analyses are given.
