Skeleton compact type rubber asphalt ultrathin wearing layer and preparation method thereof
The invention discloses a skeleton compact type rubber asphalt ultrathin wearing layer, comprising aggregate, rubber modified asphalt, an anti-stripping agent, a warm mixing agent and lignin fibers, wherein a paving thickness is 10-20 mm; the gradation type of the aggregate is a skeleton compact type, and the maximum nominal particle size of the aggregate is 9.5 mm; the rubber modified asphalt isprepared by adding 70-mesh waste rubber tire powder accounting for 17.5%-18.8% of the total mass of the rubber modified asphalt into A-grade 70 # road petroleum asphalt, and conducting heating, stirring and swelling; and the warm mixing agent is added to lower mixing and construction temperature. The rubber modified asphalt ultrathin wearing layer has favorable pavement performance, is energy-saving and environment-friendly, and has the advantages of high skid resistance and durability.
一种骨架密实型橡胶沥青超薄磨耗层，其组成包括集料、橡胶改性沥青、抗剥落剂、温拌剂以及木质素纤维，铺装厚度10～20mm。集料的级配类型为骨架密实型，最大公称粒径9.5mm。橡胶改性沥青通过向A级70#道路石油沥青中添加占橡胶改性沥青总质量17.5％‑18.8％的70目废旧橡胶轮胎粉，经加热搅拌溶胀后制得。通过添加温拌剂降低拌和与施工温度，橡胶改性沥青超薄磨耗层的具有良好的路用性能，同时也节能环保。该超薄磨耗层具有高抗滑性能及耐久性的优点。
