摘　　要：针对目前国内缺乏沥青混合料离析评价方法与评价指标的情况,在调研国内外资料基础上,对比分析各种不同评价方法,特别是无损检测方法,评定各种方法的适用性及优缺点,揭示了路面施工离析评价和控制方法的发展趋势。研究表明:使用激光断面仪和核子密度仪来评价混合料离析是较为快速有效的,而且对路面没有损坏;使用红外线温度记录仪可以有效控制现场施工温度离析,提高施工质量。On the conditions that our country lack corresponding evaluation method , extensive literature on segregation evaluation methods especially Non-destructive methods are presented in the paper.The advantage, disadvantage and suitability are analyzed. It is worthwhile using the non-destructive methods in the evaluation of segregation. The results show that it is feasible to evaluate segregation with nuclear density and laser surface measurement texture measurement, and control the temperature segregation in construction with infrared thermograph.
