Rubber asphalt stress absorbing layer and preparation method thereof
The invention provides a rubber asphalt stress absorbing layer and a preparation method thereof.The asphalt stress absorbing layer comprises 5%-15% of coarse aggregate, 70%-80% of fine aggregate, 2%-10% of toughening filler and 10%-15% of rubber modified asphalt, and the coarse aggregate accounts for 5%-15%, the fine aggregate accounts for 70%-80%, the toughening filler accounts for 2%-10%, and the rubber modified asphalt accounts for 10%-15%. The rubber modified asphalt is composed of heavy traffic asphalt, linear SBS, rubber powder, a solubilizer, a filler, a surface active warm mixing agent, an odor removing agent and a stabilizer. The prepared environment-friendly reaction type rubber asphalt stress absorbing layer has the advantages of being environmentally friendly, good in water damage resistance, high in fatigue performance and the like, is used for additionally paving an asphalt mixture on a cement concrete pavement, can play a role in preventing reflection cracks, and is particularly suitable for a newly-poured cement pavement subjected to original cement pavement disease treatment; the problem of pavement cracking caused by different shrinkage coefficients of an original cement pavement and a newly-poured cement pavement can be solved, and the bonding strength is improved.
本申请提供了一种橡胶沥青应力吸收层及其制备方法,该沥青应力吸收层包括粗骨料、细骨料、增韧填料和橡胶改性沥青,其中粗骨料为5‑15%,细骨料为70‑80%,增韧填料为2‑10%,橡胶改性沥青为10‑15%,并且橡胶改性沥青由重交沥青、线型SBS、橡胶粉、增溶剂、填料、表面活性类温拌剂、净味剂以及稳定剂组成。本申请制备的环保反应型橡胶沥青应力吸收层具有环保、抗水损害性好、疲劳性能高等优点,用于水泥混凝土路面加铺沥青混合料,可以起到阻止反射裂缝的作用,尤其适用于原水泥路面病害处置新浇筑的水泥路面,能够解决原水泥路面和新浇筑水泥路面因收缩系数不同导致的路面开裂,并提升黏结强度。
