Preparation process of rubber powder pavement material
The invention discloses a preparation process of a rubber powder pavement material, which comprises the steps of classifying, cleaning and drying waste tires, cutting the waste tires into waste tire blocks, coarsely crushing the waste tire blocks into waste tire particles, removing iron impurities in the waste tire particles to obtain rubber particles, finely crushing and screening to obtain rubber powder, preheating matrix asphalt, adding rubber powder and an SBS thermoplastic elastomer, shearing and stirring, adding polyphosphoric acid, stirring to obtain rubber asphalt, and uniformly mixing cement, fly ash, steel slag, rubber asphalt, quartz sand, modified fibers, gravel, a naphthalene-based superplasticizer and diatomite to obtain the rubber powder pavement material. According to the preparation process, the rubber powder is prepared from the waste tires, the rubber asphalt prepared from the rubber powder is applied to the pavement, so that the weather resistance and the aging resistance of the pavement material are improved, and the tensile strength and the crack resistance of the rubber powder pavement material are improved by adding the modified fibers into the rubber powder pavement material.
本发明公开了一种橡胶粉路面材料的制备工艺，通过将废旧轮胎分类、清洗、干燥后切成废旧轮胎块，然后将废旧轮胎块粗碎成废旧轮胎颗粒，去除废旧轮胎颗粒中的铁杂质，得到橡胶颗粒，将进行细碎，并筛分，得到橡胶粉，将基质沥青预热，加入橡胶粉和SBS热塑性弹性体，剪切搅拌后，加入多聚磷酸搅拌，得到橡胶沥青，将水泥、粉煤灰、钢渣、橡胶沥青、石英砂、改性纤维、碎石、萘系高效减水剂、硅藻土混合均匀，得到该橡胶粉路面材料；该制备工艺是利用废旧轮胎制备橡胶粉，利用橡胶粉制备的橡胶沥青，应用于路面之中，使得该路面材料的耐候性、抗老化性得以提升，将改性纤维加入至橡胶粉路面材料中，提高了橡胶粉路面材料的抗拉强度和抗裂性。
