Semi-flexible composite pavement
The invention discloses a semi-flexible composite pavement. The semi-flexible composite pavement comprises an asphalt mixture, and the asphalt mixture comprises, by mass, 10-20 parts of SBS modified asphalt, 30-60 parts of basalt coarse aggregate, 20-40 parts of a macromolecular surfactant, 5-10 parts of synthetic grease, 3-5 parts of starch glue, 10-15 parts of a humectant, 3-6 parts of limestonemineral powder, 0.2-0.3 part of triisopropanolamine, 2-4 parts of monofilament polypropylene fibers, 3 parts of lipase, 5 parts of sodium tripolyphosphate, 3 parts of butyl acrylate, 4 parts of alkylglycoside and 1-3 parts of water. The semi-flexible composite pavement disclosed by the invention adopts the asphalt mixture with high stability, high strength and high and low temperature resistance, so that the obtained semi-flexible composite pavement also has high stability and high strength.
本发明公开了一种半柔性复合路面，包括沥青混合料；所述沥青混合料按质量份数由如下组分组成：SBS改性沥青10～20份、玄武岩粗集料30～60份、20～40份高分子表面活性剂、5～10份合成油脂、3～5份淀粉胶、10～15份保湿剂、石灰岩矿粉3～6份，三异丙醇胺0.2～0.3份、单丝聚丙烯纤维2～4份、3份脂肪酶、5份三聚磷酸钠、3份丙烯酸丁酯、4份烷基糖苷以及水1～3份。本发明半柔性复合路面采用具有高稳定性、高强度和耐高低温性能的沥青混合料，从而使得到的半柔性复合路面也具有高稳定性和高强度。
