Persistent strength toughening type semi-rigid base pavement material and preparation method thereof
The invention discloses a persistent strength toughening type semi-rigid base pavement material and a preparation method thereof. The preparation method comprises the following steps: S1, weighing various grades of materials and rubber particles, S2, soaking the rubber particles with a NaOH solution, S3, drying various grades of aggregates in a drying oven to constant weight, S4, measuring cementand water, and S5, mixing the various grades of aggregates, cement, rubber particles and water in a vibrating manner to obtain a base layer pavement material. The preparation process is simple, all components in the prepared base pavement material are distributed uniformly, the bonding strength of the materials and mortar is high, the deformability of the base pavement material is improved, and the durability and fatigue-resistant performance of a pavement are improved.
本发明公开了一种持强增韧型半刚性基层路面材料及其制备方法，所述制备方法包括以下步骤：步骤S1，称取各档物料和橡胶颗粒，步骤S2，使用NaOH溶液浸泡橡胶颗粒，步骤S3，将各档集料置于烘箱中烘干至恒重，步骤S4，量取水泥和水，步骤S5，将各档集料、水泥、橡胶颗粒和水振动拌合获得基层路面材料；本发明制备过程简单，制备的基层路面材料中各组分分布较为均匀，物料与砂浆的结合强度较高，基层路面材料的变形能力提高，路面的耐久性和疲劳性能提高。
