| Abstract: | We put forward a new way to make semi-rigid base material with steel slag,the optimal moisture contents were picked up when the 7-days unconfined compressive strengths met Chinese regulatory requirements. The semi-rigid base material used steel-slag as aggregates purely has obtained higher compressive strength, higher splitting strength and higher compressive modulus after a longer time hydration. By Stability test, it was found that the stability,erosion resistance,and crack resistance of the semi-rigid base materials with steel-slag were all superior to China"s traffic regulations. |
| Keywords: | Steel slag Semi-rigid base Road performance |
