基于回收木质集料的沥青混合料路用性能研究

Study on Road Performance of Asphalt Mixture Based on Reclaimed Wood Aggregate

用回收木质材料代替石料制备了沥青混合料,采用室内正交试验设计了不同的材料组成,研究了不同材料组成对木质集料沥青混合料性能的影响。结果表明:结合料对木质集料混合料路用性能的影响最为显著;在最佳材料组成下,木质集料混合料的路用性能可以满足要求,但由于水稳定性能偏低,适宜用于干旱、半干旱气候分区。

Reclaimed wood material was used for the preparation of asphalt mixture instead of stone aggregate. Various material compositions were designed by orthogonal test, in order to study the influence of material compositions on the road performance of asphalt mixture with wood aggregate. The results indicate that the road performance of asphalt mixture, which is principally influenced by asphalt binders, can meet the performance requirements of asphalt pavement. However, the mixture can only be applied in drought or half-dried areas due to its ow water stability
