SBS改性剂对寒区彩色沥青性能影响分析

彩色沥青是打破路面颜色的一种新型材料,成为引导交通、改变行车环境的一种新的元素。彩色沥青的性能与常规沥青有相似之处——高温环境产生车辙、低温环境容易开裂,相对于南方,黑龙江省彩色沥青的应用起步较晚,大多实体项目直接对其进行应用,没有对彩色沥青的性能进行深入研究,也未研究最适合北方寒区应用的彩色沥青。本工作选取黑龙江省常用的彩色沥青,在掺加SBS改性的基础上研究其性能,并引进SHRP计划中的高低温试验探寻掺加SBS改性剂的彩色沥青在寒区的性能,最终得到SBS改性剂对寒区彩色沥青各项性能的影响。该工作对黑龙江省寒区彩色沥青的研究有着重要的参考价值。

Effect of SBS Modifier on Performance of Coloured Asphalt in Cold Region

Color asphalt is a new type of material to break the color of the road, and it is a new element to guide the traffic and change the driving environment. Its performance with the conventional asphalt performance of colored asphalt are similar:high temperature rutting, low temperature crack easily, relative to the south of Heilongjiang Province, the application of color asphalt started late, most of the project entity directly to its application, there is no performance of the color asphalt in depth research, neither to find the most suitable for the application of color asphalt in North China. The research of this paper selects the color asphalt commonly used in Heilongjiang Province based on the performance of modified with SBS, and explore the added SBS modifier in the performance of color asphalt in the introduction of high and low temperature test in the SHRP plan, finally get the SBS modifier in the analysis of the color asphalt performance is affected by the study on Heilongjiang Province cold color asphalt has important reference value.
