摘要
对加铺超薄磨耗层后的路面沥青混合料进行试验分析。试验结果与分析表明:加铺超薄磨耗层后的混合料级配和油石比满足规范的AC-13的技术要求,说明超薄磨耗层路面可进行再生利用。对再生混合料进行高温性能、水稳定性能和低温性能试验,发现含有超薄磨耗层的再生混合料的高温性能、水稳性能和低温性能均满足规范要求。再生后路面压实度、平整度、渗水系数等指标满足规范要求。
This paper analyzes ultra-thin wearing course material. The results and analyses show that gradation and asphalt aggregate ratio of the material meet the standard of AC-13 Technology, and ultra-thin wearing course material can be regenerated. High temperature stability, moisture stability, low temperature property meet the requirements of HMA in specifications. Pavement compactness, smoothness, water permeability coefficient index can meet the requirements of specification after regeneration.
