摘要 通过对再生混凝土集料的特性及其用于水泥稳定碎石技术的研究,认为再生混凝土集料特别是再生混凝土细集料对水泥稳定碎石强度的影响非常大.同时,研究了再生集料的用法和用量、水泥稳定碎石延时成型的强度下降规律以及掺再生集料的水泥稳定碎石耐久性能等,发现掺再生集料的水泥稳定碎石强度发展良好,耐久性能十分优异,可在高等级公路上应用. Based on some exploratory research of characteristics of recycled concrete aggregate (RCA) and technology of recycled concrete aggregate for cement stabilized gravel, it is found that recycled concrete aggregate, particularly, fine recycled concrete aggregate has a great influence on the strength of cement stabilized gravel. Meanwhile, the usage and the use level of recycled aggregate were studied. The decreasing tendency of strength with delay forming of cement stabilized gravel and the durability of recycled concrete aggregate for cement stabilized gravel were studied. It is found that strength of cement stabilized gravel with recycled concrete aggregate is good, durability is very excellent, and can be widely applied in highway construction.
