橡胶颗粒沥青混合料破冰性能研究
|
摘要
冬季降雪使许多公路与城市道路出现积雪结冰的问题非常严重,路面结冰不仅影响行车安全,同时也降低了道路的通行能力和运输效率,给我国道路安全和经济发展带来了严重的影响。目前,常用的除冰雪方法是在路面上撒布融雪剂,但融雪剂具有腐蚀性,易污染环境。其他方法中,人工清除法效率低,费用高；机械除雪只适用于便于管理的较小范围的除雪；热力融冰雪方法造价较高且技术并不成熟。
为此从混合料自身角度出发,寻找一种既有效又环保的破冰的方法成为了一个大的研究方向。橡胶颗粒沥青混合料作为一种新型的道路路面混合材料恰好具有这种性能,同时能够解决废旧轮胎的处理问题、缓解我国的环境压力、节约资源。
论文对橡胶颗粒沥青混合料的级配组成设计方法进行了研究,提出采用体积设计法进行混合料级配组成设计并验证了其可行性；对橡胶颗粒适宜性进行了研究,混合料的体积特性及路用性能试验结果表明,橡胶颗粒宜优先选用30目,且推荐掺量为3%；针对橡胶颗粒易脱粒的问题,掺加多种添加剂进行抗剥落性研究,结果表明石灰效果最好,且最优添加剂量为1.2%；对路用性能进行了研究,研究结果表明,橡胶颗粒沥青混合料在满足水稳定性和力学性能的基础上,具有更好的高温稳定性和低温抗裂性；采用破冰仪进行了路面破冰性能试验,结果表明橡胶颗粒的存在使沥青混合料路面具有了破冰的效果,且与橡胶颗粒粒径、掺量、环境温度、冰层厚度有关。
Winter snowfall makes road pavement appeared snow icy phenomenon seriously, which not only affects the traffic safety, but also affects the traffic capacity of the road transport efficiency, brought serious influence and road safety and economic development of our country. At present, the commonly used method of breaking the ice on the road is to spread deicing salt, deicing salt is not only corrosive but also can cause environmental pollution. Other methods, the manual removal method has low efficiency and high cost; high cost of heating method for melting ice and snow, and technology is not mature.
Therefore, from the point of this mixture itself, to find a scientific and effective, energy-saving environmentally friendly method of de-icing into a large research direction. Rubber asphalt mixture particle as a new road pavement mixed materials have this performance; just And can also solve the junked tire issues, ease China environmental pressure, conservation of resources.
In this paper, the gradation composition design method of asphalt rubber particles was studied, the design method proposed by volume of the mixture gradation design and validate its feasibility; suitability of the rubber particles were studied, determine the optimum size of rubber particles was 30 mesh when the additive amount is 3%; to direct at the problem of the rubber particles easily threshing, the study of anti-strip performance joining several additives was conducted, the results showed that the lime has the best effect, the optimal amount of additive is 1.2%; the results show that asphalt rubber particles can not only meet the basic performance of water stability and mechanical properties, but also has better high temperature stability and low temperature crack resistance; the performance of de-icing was tested, the results of tins experiment showed that the presence of rubber particles makes the asphalt pavement gets the ability of de-icing, and it is effected by rubber particle size, additive amount, ambient temperature, the thickness of ice.
