Rolling and curing type water-resistant foamed asphalt concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to rolling and curing type water-resistant foamed asphalt concrete and a preparation method thereof. The foam asphalt is prepared from the following components: foam asphalt, aggregate, cement, lime, fibers, rubber powder, unsaturated polyester, a silane coupling agent, an initiator microcapsule and an accelerant microcapsule. On the premise that the advantages of workability, environment friendliness and application performance of the foamed asphalt concrete are reserved, the rolling and curing of the foamed asphalt concrete are realized by adopting a microcapsule technology. In other words, the foamed asphalt concrete cannot be subjected to chemical curing reaction in the storage, transportation and paving processes; in the forming process, through rolling of road building equipment and mutual extrusion of stone materials, the curing agent microcapsules and the accelerant microcapsules are broken, and the unsaturated polyester in the mixture is subjected to a curing reaction with the curing agent and the accelerant.
本发明属于建筑材料技术领域，具体涉及一种碾压固化型耐水泡沫沥青混凝土及其制备方法。包含如下组分：泡沫沥青、集料、水泥、石灰、纤维、胶粉、不饱和聚酯、硅烷偶联剂、引发剂微胶囊、促进剂微胶囊。碾压固化型耐水泡沫沥青混凝土在保留泡沫沥青混凝土和易性、环保性和应用性能优势的前提下，采用微胶囊技术，实现了泡沫沥青混凝土的碾压固化。即，在储存、运输、摊铺过程中泡沫沥青混凝土不会发生化学固化反应；在成型的过程中，通过筑路设备的碾压，石料之间相互挤压，使固化剂微胶囊和促进剂微胶囊破裂，混合料中的不饱和聚酯与固化剂、促进剂发生固化反应。
