RAP 掺量对泡沫温拌沥青混合料水稳定性能的影响

摘要

In order to study the impact of RAP material mixing dosage upon warm-foam-mixing asphalt mixture water stability,the paper applies immersion Marshall test and freezing-thawing test,and evaluates water stability of warm-foam-mixing asphalt mixture. Results show that:residual stability of immersion Marshall test and freezing-thawing strength rate has good coordination with RAP material mixing dosage;and will reduce with RAP material mixing dosage increasing.%为研究RAP材料掺量对泡沫温拌沥青混合料水稳定性能的影响，采用浸水马歇尔试验和冻融劈裂试验，对泡沫温拌再生沥青混合料的水稳定性能进行了评价，结果表明：浸水马歇尔试验的残留稳定度与冻融劈裂强度比与RAP材料掺量之间存在较好的相关关系，随着RAP材料掺量的增加呈现减小的趋势。
