水泥-乳化沥青冷再生混合料配合比设计及其水稳定性评价

Proportion design and water stability of cement-asphalt emulsion cold recycling mixtures

采用不同比例的新集料与沥青回收料(RAP)进行配合,设计了3种不同级配的乳化沥青冷再生混合料,研究了水泥用量和RAP用量对混合料水稳定性的影响。结果表明,掺入一定量的水泥对提高混合料水稳定性的有利。混合料中RAP用量越高,其水稳定性越低。

We designed three different ratios of new aggregates and RAP. We proportions of cement-asphalt emulsion cold also investigated the impacts of cement and Results show that cement addition can improve their water stability, but optimum reduces with the increase of RAP content. recycling mixtures by different mixing RAP contents on their water stability. content exists.
