Urban asphalt pavement anti-skid low-noise structure
The invention discloses an urban asphalt pavement anti-skid and low-noise structure which comprises a noise-reducing and anti-skid surface layer arranged on a pavement base layer; the sound absorption layers are arranged on the two sides of the pavement base layer in a manner of being perpendicular to the noise-reducing and anti-sliding surface layer; wherein the noise-reducing anti-sliding surface layer is formed by paving raw materials including coarse aggregate, fine aggregate, mixed fibers and a binding material, and the mass ratio of the coarse aggregate to the fine aggregate to the mixed fibers to the binding material is 35: 51: 8.5: 5.5; wherein the mixed fibers are saw-tooth-shaped steel fibers with the diameter of 0.2 mm and the length of 1.8 mm and polyethylene fibers with the length of 1.6 mm, and the mixing mass ratio of the saw-tooth-shaped steel fibers to the polyethylene fibers is 1: 4. By optimizing the component proportion of the surface layer and adding the mixed fibers, the porosity is increased and the anti-sliding and noise-reducing effects are improved under the condition of ensuring the strength of the pavement.
本发明公开了城市沥青路面抗滑低噪结构，包括：降噪抗滑面层，其被配置于路面基层之上；吸声层，其垂直所述降噪抗滑面层设于路面基层的两侧；其中，降噪抗滑面层由粗集料、细集料、混合纤维、粘结材料为原料铺筑而成：粗集料、细集料、混合纤维、粘结材料的质量比为35:51:8.5:5.5；其中，混合纤维为直径为0.2mm、长度为1.8mm的锯齿形钢纤维和长度为1.6mm聚乙烯纤维，锯齿形钢纤维和聚乙烯纤维的混合质量比为1:4。本发明通过优化面层组分配比，增加混合纤维，在保证路面强度的情况下，增加空隙率，提升抗滑、降噪的效果。
