摘要
为了解决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,在大量调查 国内外资料基础上,对比分析了各种不同评价方法,特别是无损检测方法。分析了各种方法的 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 our country lack corresponding evaluation method, the finds extensive literature review on segregation evaluation methods especially Non-destructive methods are presented in the paper. The advantage, disadvantage and suitability were analyzed. It is worthwhile using the non-destructive methods in the evaluation of segregation. The results show that it is feasible to evaluate segregation by means of nuclear density and laser surface texture measurement, and control the temperature differentials in construction by infrared thermograph.
