橡塑合金材料在再生沥青混合料中的应用研究

Study on Application of Rubber-Plastic Alloy Materials in Recycled Asphalt Mixture

以橡塑合金为再生改性材料,采用新集料和废旧沥青混合料制备了三种不同的沥青混合料,对比研究了橡塑合金对新混合料和再生混合料路用性能的影响。结果表明:橡塑合金可以显著提高沥青混合料的高、低温性能和水稳定性,且掺入50%废旧沥青混合料后仍能保持较好的路用性能,极具应用潜力。

Three kinds of different asphalt mixtures have been prepared by using rubber and plastic alloy as regenerated modified materials, as well as new aggregates and wasted asphalt mixtures. The comparison of the effects of rubber and plastic alloys on the road performance of new and recycled mixtures has been made. The results have shown that rubber-plastic alloy with great application potential can significantly improve the high and low temperature performance and water stability of asphalt mixture, and it can maintain good road performance after the mixture of 50% RAP.
