| Abstract: | The characteristics of strength and durability for recycled coarse aggregation concrete for road pavement repair are studied in this paper.It includes flexual test and compression test as well as anti-permeability test.Its results show that it improves strength,anti-permeability and anti-sulfate erosion level of concrete greatly by adding appropriate CUFG.Its early strength can meet demand of heavy load traffic and heavy weight traffic.At last,the durability of the concrete also meets demand for road pavement construction. |
