| Abstract: | Improvement of recycled aggregate of old cement concrete is mainly to settle the issue of water absorption rate. Study on the basic properties of recycled aggregate is divided into ordinary recycled aggregate and milling one. The compressive strength test of water stable aggregate includes compaction test and unconfined compressive strength test. Drying shrinkage of cement stabilized recycled aggregate is an important indicator to evaluating the binding material durability. |

| Keywords: | recycle concrete aggregate cement stabilized base course unconfined compressive strength shrinkage strain road performance |
