Recycled asphalt concrete prefabricated part and preparation method thereof
The invention belongs to the field of recycled concrete materials, and particularly relates to a recycled asphalt concrete prefabricated part and a preparation method thereof. The recycled asphalt concrete prefabricated part comprises the following components in parts by weight: 100 parts of a waste asphalt mixture, 2-4 parts of fresh asphalt, 8-12 parts of a mineral admixture and 5-10 parts of an asphalt modifier, wherein the asphalt modifier contains SBS modified asphalt, SBS and polymer fibers in a weight ratio of (3-5): (1.5-3.5): (0.5-1.5). The invention finds that by optimizing the formula, the compatibility of the waste asphalt mixture and the fresh asphalt can be obviously improved, and meanwhile, the adverse effect of cracks in the recycled aggregate on the material performance can be greatly avoided, so that the recycled asphalt concrete prefabricated component has good mechanical property and water resistance. And the preparation method is simple and efficient, and is beneficial to popularization and application in actual production.
本发明属于再生混凝土材料领域，具体涉及一种再生沥青混凝土预制构件及其制备方法。本发明中的再生沥青混凝土预制构件包括如下重量份组分：废弃沥青混合料100份、新鲜沥青2～4份、矿物掺合料8～12份、以及沥青改性剂5～10份；其中，沥青改性剂中含有重量比为3～5：1.5～3.5：0.5～1.5的SBS改性沥青、SBS和聚合物纤维。本发明发现，通过优化配方，能够使废弃沥青混合料与新鲜沥青的相容性得到显著改善，同时能较大程度避免再生骨料内部的裂纹对材料性能的不利影响，从而使得再生沥青混凝土预制构件具有良好的力学性能及抗水性能。且本发明的制备方法简单高效，有利于在实际生产中进行推广应用。
