摘要沥青作为十分优秀的道桥及公路建设材料,应用十分广泛,虽然对其改性可以增强许多性能,但沥青施工对温度的超高要求,运输的高条件以及施工时排放出的有毒有害气体依然无法避免,但是冷铺环氧沥青不仅极大程度地提升了沥青的力学性能,更解决了施工的运输问题,降低了施工温度,并且减少了有毒有害气体的排放,所以冷铺环氧沥青具有着无与伦比的发展前景。47041
本课题根据环氧树脂、环氧树脂固化剂、沥青稀释剂的具体参数以及固含量设计了配方,并经过多组试验,确定了固化剂与环氧树脂的最佳的配比。并且根据实验得出了不同含量环氧树脂的添加导致最后的固化程度。查阅文献,根据沥青的测试指标,制作了符合实验室使用的力学性能测试所需的测试磨具,例如拉伸的哑铃型磨具,抗压性能的圆柱型磨具,粘结性能的打孔样片。然后对制备的样品进行了力学性能的测试,分多组实验,测试不同含量的环氧树脂对样品的影响。

Abstract
Asphalt as a very outstanding bridge and road construction materials, is widely used。Although the modification can improve the performance , but the high Construction temperature, high transport conditions and the construction of emissions of toxic and harmful gases still can not be avoided.But the cold Shop epoxy asphalt not only greatly enhance the mechanical properties of the asphalt, even more to solve the transportation problem of construction, reduce the construction temperature, and reduce the toxic and harmful gas emissions. Based on the above advantages, the epoxy asphalt has a unique development prospect.
In this expreiment, according to the specific parameters of epoxy resin, epoxy resin curing agent, asphalt diluent and solid content design formula, and after several groups of experiments, the best ratio of curing agent and epoxy resin was determined. And according to the experiment, the different content of epoxy resin was added to lead to the final degree of cure. Literature. According to the test indexes of asphalt, making the conforms to the laboratory testing the mechanical properties required test tools, such as tensile dumbbell type abrasive tool, compressive properties of cylindrical grinder, bonding properties of drilling samples. Then the mechanical properties of the prepared samples were tested, and the effect of different content
of epoxy resin on the sample was tested
KeyWords:Cold-mix asphalt; Modified asphalt;curing agents in epoxy; solidification
