Epoxy asphalt elastic curing ballast bed material and curing method thereof
The invention discloses an epoxy asphalt elastic curing ballast bed material and a curing method thereof, and belongs to the technical field of rail transit materials. The epoxy asphalt ballast bed material comprises the following components in parts by mass: 100 parts of mineral aggregate; 6-8 parts of mineral powder; 8-12 parts of rubber particles; and 9-12 parts of epoxy asphalt. The rubber particles have the characteristic of oil absorption swelling, and the characteristic has certain influence on the skeleton stability and mechanical property of the mixture, so that the test piece prepared by the curing method disclosed by the invention has relatively small volume expansion rate and relatively excellent mechanical property, and the stability and strength of the epoxy asphalt elastic curing ballast bed material can be effectively ensured; therefore, the performance requirements of the epoxy asphalt elastic curing ballast bed in a track structure are met.
本发明公开了一种环氧沥青弹性固化道床材料及其养生方法，属于轨道交通材料技术领域。环氧沥青道床材料包括以下质量份数的组分：矿质集料100份；矿粉6~8份；橡胶颗粒8~12份；环氧沥青9~12份。由于橡胶颗粒具有吸油溶胀的特点，该特性对混合料的骨架稳定性和力学性能具有一定的影响，通过本发明的养生方法制备得到的试件具有较小的体积膨胀率和较优的力学性能，可有效保证环氧沥青弹性固化道床材料的稳定性和强度，以满足环氧沥青弹性固化道床在轨道结构中的性能要求。
