柴油泄漏对沥青路面使用性能的影响研究

为研究柴油泄漏对沥青路面使用性能的影响,依托汕梅高速柴油泄漏应急处治项目,室内试验利用红外光谱仪研究开展了油蚀机理研究。现场检测研究开展了柴油泄漏对沥青路面表观状况、摆值(BPN)、渗水状况的影响分析,钻取芯样并开展了沥青混合料的密度、高温性能及水稳定性的对比分析及对回收沥青性能的影响研究。结果表明:柴油油蚀机理在于吸收峰处官能团数量的变化;沥青路面在受柴油污染后会出现不同程度的颜色变黑、路表变滑现象;柴油泄漏造成沥青混合料密度下降;且沥青含量、沥青三大指标下降,并导致沥青混合料水稳定性和高温性能均产生较大幅度下降。

Research of Diesel oil spill's impact on road performance of asphalt pavement

To study the impact of the diesel oil leaks on the road performance of asphalt pavement, based on the diesel oil leaksl emergency treatment project of ShanMei Highway, the mechanism of oil corrosion was studied through Infrared spectrometer ,and the impact of the diesel oil leaks on road performance was analyzed including apparent condition, BPN and water seepage condition.By comparison and analysis on the density, high-temperature performance,water stability, and recycled asphalt of core samples. The results show that the oil corrosion mechanism is mainly the change in the number of functional groups at the absorption peak.; asphalt pavement color turns to be black and anti-skid coefficient reduced ,asphalt mixture density,asphalt content and the three index of asphalt decreased after polluted; asphalt mixture water stability and high temperature performance decreased greatly.
