摘　　要：泡沫沥青温拌技术可有效降低沥青混合料的加热温度,以SBS改性沥青大粒径透水性沥青混合料为研究对象,结合实体工程采用泡沫沥青温拌技术,研究泡沫温拌沥青混合料性能衰减规律,并与传统沥青混合料性能进行对比。试验结果表明:泡沫温拌沥青混合料采用"体积等效"原则确定混合料的击实温度,可以实现降低击实温度25℃以上;经性能试验验证,泡沫温拌大粒径透水性沥青混合料抗飞散性能有所提高,抗析漏性能有所降低。总体来看,泡沫温拌大粒径透水性沥青混合料的综合路用性能同传统混合料接近,可以实现节能减排的效果,具有很好的应用推广价值。Foam asphalt warm technology can effectively reduces temperature of asphalt mixture,this paper which studies on SBS modified large stone porous asphalt mixture studies on degradation law of properties of foam asphalt warm mixture combining with physical engineering,and compares with performance of the traditional asphalt mixture.The test results show that the foam warm asphalt mixture which determines compaction temperature by volume equivalent principle can reduces compaction temperature more than 25℃;the performance tests show that anti-flying performance of foam warm large stone porous asphalt mixture improves,but anti-leakage performance decreases.Overall,comprehensive road performance of foam warm large stone porous asphalt mixture which can achieves to conserve energy and reduce emission is similar with the traditional mixture,and it has good application and promotion value.
