Elastic curing ballast bed material and indoor test piece forming and manufacturing method thereof
The invention discloses an elastic curing ballast bed material and an indoor test piece forming and manufacturing method thereof, which belong to the technical field of rail transit materials. The elastic curing ballast bed material comprises the following components in parts by mass: 100 parts of limestone, 6-8 parts of mineral powder, 8-12 parts of rubber particles, and 9-12 parts of epoxy asphalt. According to the elastic curing ballast bed material, the epoxy asphalt is adopted as a main curing material to cure the limestone, the ballast bed material high in strength and excellent in performance can be obtained, the elasticity of the ballast bed material is improved by adding the specific component rubber particles, and the raw materials are environmentally friendly and economical; the construction cost of the elastic curing ballast bed can be well reduced, the fatigue repeated loading test verifies that the performance of the test piece obtained through the molding method can meet the performance requirement of the polyurethane curing ballast bed block, the ballast bed structure with the performance not weaker than the performance of the polyurethane curing ballast bed can be obtained at the low cost, the construction process is simple, and the method is suitable for popularization and application in the rail transit field.
本发明公开了一种弹性固化道床材料及其室内试件成型制作方法，属于轨道交通材料技术领域。弹性固化道床材料包括以下质量份数的组分：石灰岩100份；矿粉6~8份；橡胶颗粒8~12份；环氧沥青9~12份。本发明的弹性固化道床材料，采用环氧沥青作为主要固化材料，对石灰岩进行固化，能得到强度高且性能优越的道床材料，且通过特定组分橡胶颗粒的添加，提升了道床材料的弹性，本发明原材料的选材环保经济，能很好地降低弹性固化道床的造价，通过本发明的成型方法得到的试件经疲劳重复加载试验验证，性能均能满足聚氨酯固化道床块性能要求，能更低成本的得到性能不弱于聚氨酯固化道床的道床结构，且施工工艺简单，适于在轨道交通领域推广应用。
