摘　　要：研究了道路路面修补的再生粗骨料混凝土的强度和耐久性,包括抗折试验、抗压试验、抗渗试验、抗硫酸盐侵蚀试验.试验结果表明:当掺入适量的CUFG可以大大提高它的强度、抗渗等级和明显改善它的抗硫酸盐腐蚀能力;它的早期强度能达到重载交通和特重载交通开放要求,其耐久性能够满足道路路面工程的需要.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.
