| Abstract: |
| 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. |
