Semi-flexible pavement material based on thermal regeneration asphalt mixture and construction method of pavement material
The present invention provides a semi-flexible pavement material based on a thermal regeneration asphalt mixture and a construction method of the pavement material. The material comprises an asphalt mixture base material and agrouting material; theasphalt mixture base material comprises a thermal regeneration asphalt mixture and a new asphalt mixture, and the thermal regeneration asphalt mixture comprises a recovered asphalt mixture, a regenerant, an active agent and a fusion agent, wherein the active agent is composed of two or more of polyethylene wax, modified isomeric fatty group terminated polyether, oxidized polyethylene wax, a modified branched chain alcohol ether ethoxy compound and castor oil polyethylene glycol ether; and the grouting material comprises cement, silica fume, fineaggregate, a performance enhancer, dispersible styrene-butadiene latex powder and water, and the performance enhancer comprises a water reducing agent, an air entraining agent, a defoaming agent and awater retaining agent. The invention solves the problems that the strength, stability, porosity and other related material properties of the thermal regeneration asphalt mixture are reduced to a certain extent, and the thermal regeneration asphalt mixture is generally used for the lower surface layer or base layer of a road.
本发明提供了一种基于热再生沥青混合料的半柔性路面材料及其施工方法，该材料包括：沥青混合料基料，包括热再生沥青混合料和新沥青混合料，所述热再生沥青混合料包括回收沥青混合料、再生剂、活性剂和融合剂，所述活性剂由聚乙烯蜡、改性异构脂肪基封端聚醚、氧化聚乙烯蜡、改性支链醇醚乙氧基化合物、蓖麻油聚乙二醇醚中两种或两种以上组成；以及灌浆料，包括水泥、硅灰、细集料、性能增强剂、可分散丁苯乳胶粉和水，所述性能增强剂包括减水剂、引气剂、消泡剂和保水剂。本发明解决了热再生沥青混合料在强度、稳定性、空隙率等相关材料性能都有一定程度降低，一般用于道路的下面层或基层的问题。
