Pouring type large-thickness water-stable macadam base and paving method thereof
The invention discloses a pouring type large-thickness water-stable macadam base and a paving method thereof, and belongs to the field of road engineering. The pouring type large-thickness water-stable macadam base is composed of a large-thickness macadam framework structure and a grouting material, the large-thickness macadam framework structure is designed in a two-layer mode, the lower layer is a super-large-particle-size aggregate layer, the upper layer is a medium-particle-size aggregate layer, cement cementing materials are adopted, and the grouting material is poured into the large-thickness macadam framework structure at a time. The mass percent of the recycled powder in the powder of the grouting material is not less than 50%. Compared with the prior art, the pouring type large-thickness water-stable macadam base has the advantages that the dry shrinkage and temperature shrinkage performance of the water-stable macadam base can be improved, transverse cracks of a semi-rigid base are reduced, the service life of a pavement structure is prolonged, the pavement forming and curing time is short, and compared with two-layer respective curing construction, the construction efficiency is improved. And the construction period of road maintenance can be greatly shortened, and high application and popularization value is achieved.
本发明公开了一种灌注式大厚度水稳碎石基层及其铺装方法，属于道路工程领域。所述灌注式大厚度水稳碎石基层由大厚度碎石骨架结构和灌浆材料组成，所述大厚度碎石骨架结构采用两层式设计，下层为超大粒径骨料层，上层为中等粒径骨料层，采用水泥胶结料，所述灌浆材料一次性灌注于大厚度碎石骨架结构中，且灌浆材料的粉料中回收粉的质量百分比含量不低于50％。与现有技术相比，本发明的灌注式大厚度水稳碎石基层能够改善了水稳碎石基层的干缩和温缩性能，减少半刚性基层的横向裂缝，提高路面结构的使用寿命，且路面成型和养生时间短，相较于两层分别养生施工，可以大大缩短道路养护的工期，具有很高的推广应用价值。
