Drainage asphalt mixture and preparation method and application thereof
The invention provides a drainage asphalt mixture and a preparation method and application thereof. The drainage asphalt mixture is prepared from the following components: polymer modified asphalt, graded aggregate and composite fibers, wherein the composite fibers comprise glass fibers and granular lignin fibers, and the mass ratio of the glass fibers to the granular lignin fibers is 1: (0.3-3). According to the drainage asphalt mixture, the polymer modified asphalt is used for replacing high-viscosity modified asphalt, so that the material cost is saved to a great extent, and the drainage asphalt mixture has relatively good economic benefits. Moreover, the drainage asphalt mixture is relatively excellent in high-temperature stability, low-temperature stability, water-resistant stability and the like, so that the drainage asphalt mixture can be used as a surface layer to be laid on an impermeable structural layer, and a formed asphalt pavement has the advantages of good drainage performance, good skid resistance, capability of reducing driving noise and the like.
本发明提供一种排水沥青混合料及其制备方法和应用。所述排水沥青混合料包括以下组分：聚合物改性沥青、级配型集料以及复合纤维；其中，所述复合纤维包括玻璃纤维和粒状木质素纤维，所述玻璃纤维和粒状木质素纤维的质量比为1:0.3～3。本发明的排水沥青混合料中使用聚合物改性沥青代替高粘改性沥青，在很大程度上节省了材料成本，具有较好的经济效益。并且，本发明的排水沥青混合料的高温稳定性、低温稳定性以及耐水稳定性等均较为优异，从而可以作为面层铺设在不透水结构层上，所形成的沥青路面具有良好的排水性能、抗滑性能和降低行车噪音等优点。
