摘　　要：选取几种改性沥青混合料,通过肯塔堡飞散试验,评价不同种类改性沥青混合料的抗松散能力和水稳定性,并对不同种类改性沥青混合料进行经济性分析。结果表明:6%、5%掺量的SBS改性沥青混合料、4%SBS+1%PE的复合改性沥青混合料具有较好的抗松散能力和水稳定性;SBS掺量的提高可以明显提高改性沥青混合料的抗松散能力和水稳定性。综合考虑成本和路用性能,推荐在工程上选用高掺量SBS的改性沥青混合料。标准肯塔堡飞散试验与浸水飞散试验结果得出的改性沥青混合料抗剥落与抗水损性能排序高度一致,二者可相互映证。Several kinds of asphalt mixtures are selected to evaluate the anti-loose abilities and water stabilities of the different modified asphalt mixtures through Kentucky scatter test, and the economic analysis of the different modified asphalt mixtures are carried out. The results show that 6% and 5% SBS modified asphalt mixtures, and 4% SBS + 1% PE composite modified asphalt mixture have better anti-loose abilities and water stabilities. The increase of SBS content can significantly improve the anti-loose ability and water stability of modified asphalt mixture. Comprehensively considering the cost and road performance, it is recommended to select the modified asphalt mixture with high content of SBS in the project. The results of standard Kentucky scatter test and immersion scatter test show that the anti-stripping and anti-water loss performances of modified asphalt mixture are highly consistent. The both can mirror each other.
