Lime-stabilized regenerated macadam for rapid drainage roadbed structure
The invention relates to the technical field of materials for the highway industry, in particular to lime-stabilized regenerated macadam for a rapid drainage roadbed structure, which is composed of regenerated broken stone, lime and water. The regenerated macadam comprises the following components in percentage by mass: 30%-35% of broken stone with the particle size of less than 5mm, 20%-25% of broken stone with the particle size of 5mm-10mm, 20%-30% of broken stone with the particle size of 10mm-20mm, 5%-10% of broken stone with the particle size of 20mm-25mm and 5%-10% of broken stone with the particle size of 25mm-31.5 mm. On one hand, the grading of the regenerated broken stone is scientifically determined, so that the mixed regenerated broken stone has more reasonable particle size distribution and pore distribution, the compactness of the lime-stabilized regenerated macadam is improved, and the bearing capacity of the regenerated macadam is further improved; and on the other hand, damage to ecology caused by mining stones can be effectively reduced, cyclic utilization of waste base materials excavated out of old roads is achieved, lime is used for cementing the broken stone, the broken stone is used in a base filler of the roads on a large scale, and the broken stone is regenerated into the base materials after being stabilized. The lime-stabilized regenerated macadam has huge economic, environment-friendly and social benefits.
本发明涉及公路行业用料技术领域，尤其涉及快速排水路基结构用石灰稳定再生碎石，由再生碎石、石灰和水组成；再生碎石包括以下质量百分比的组分：30％‑35％粒径小于5mm的碎石、20％‑25％粒径为5mm‑10mm的碎石、20％‑30％粒径为10mm‑20mm的碎石、5％‑10％粒径为20mm‑25mm的碎石和5％‑10％粒径为25mm‑31.5mm的碎石。本发明一方面科学地确定再生碎石的级配，使得混合后的再生碎石具有更为合理的粒径分布和孔隙分布，从而使得该石灰稳定再生碎石密实度提高，进一步提升再生碎石的承载力；另一方面还能够有效地减少矿山开采石料对生态造成的破坏，实现了对老旧公路挖除出的废旧基层材料的循环利用，并依靠石灰进行胶结碎石被大规模地用于公路的基层填料中，稳定后再生成为基层材料，具有巨大的经济、环保和社会效益。
