| Abstract: | Dealing with the broken old cement concrete pavement blocks by the method of indoor ball milling,the recycled aggregate can be attained.handling with it,the recycled coarse aggregate with high anti-crushing and low water absorption and a lot of ball milling can be got.The compressive strength test,unconfined compression tests and freeze-thaw cycle test were conducted and the test results show that the recycled aggregate with stabilize global cement grinding has a better compression capability,water stability and frost resistance performance and achieved better utilization efficiency in the test road base. |
| Keywords: | recycled concrete aggregate milling process test pavement engineering |
