Drainage asphalt pavement structure and construction method thereof
The invention provides a drainage asphalt pavement structure and a construction method thereof.The drainage asphalt pavement structure comprises a cushion layer, a seal coat, a permeable base layer and a permeable surface layer which are sequentially laid on the top of a roadbed; the permeable base layer is prepared from the following raw materials in parts by mass: 80 to 100 parts of limestone; 3-5 parts of asphalt; 3-5 parts of mineral powder; 0.2 to 0.5 part of fiber; according to the drainage asphalt pavement structure disclosed by the invention, the permeable base layer formed by uniformly mixing the limestone, the mineral powder, the fibers and the asphalt and then paving the mixture has relatively large porosity, so that the permeability can be remarkably improved, and meanwhile, good mechanical strength is ensured.
本发明提供一种排水沥青路面结构及其施工方法，排水沥青路面结构，包括依次铺设于路基顶部的垫层、封层、透水基层及透水面层；所述透水基层以质量份数计，包括以下原料：石灰岩80～100份；沥青3～5份；矿粉3～5份；纤维0.2～0.5份；本发明中的排水沥青路面结构采用石灰岩、矿粉、纤维与沥青拌合均匀后铺设形成的透水基层具有较大的孔隙率，能够显著提升渗透性能，同时保证良好的力学强度。
