Abstract
In order to improve the pavement performance of recycled asphalt mixture,the effects of different old material content,holding time and test temperature on the pavement performance of recycled asphalt mixture were studied by preparing steel slag recycled asphalt mixture sam-ples.The test results show that the gross volume density,porosity and clearance rate of slag regenerated mixture decrease by 11.5%,6.7%and 5.5%,respectively,when the content of used material increases from 50%to 100%.Steel slag can effectively improve the road performance of recycled asphalt mixture;The longer the holding time,the lower the old material content and the higher the test temperature,the Marshall stability,the freeze-thaw splitting strength ratio and the dynamic stability of the reclaimed asphalt mixture of steel slag are improved.关键词
