Construction method of drainage asphalt concrete pavement
The invention provides a construction method of a drainage asphalt concrete pavement, which comprises the following steps: on the basis of the existing construction method, regulating the consumptionof each material to reduce the porosity, adopting modified asphalt to improve the high-temperature stability, and improving the adhesion between asphalt and an aggregate by improving the mixing amountof an anti-stripping agent. According to the invention, the two main indexes of the existing road communication void ratio and the water permeability coefficient are effectively improved, the performance requirements of the drainage asphalt pavement are ensured to be met, meanwhile, the phenomena of flying and damage do not occur in the drainage asphalt constructed by the method in a long time period, and the durability of the road is remarkably improved.
本发明提供一种排水沥青混凝土路面的施工方法，方法为：在现有施工方法的基础上通过调整各材料的用量以降低孔隙率，采用改性沥青以提高高温稳定性，通过提高抗剥落剂的掺量以提高沥青与集料的粘附性。本发明有效改善了现有道路连通空隙率以及渗水系数两项主要指标，保证满足排水沥青路面的性能要求，同时通过本发明施工的排水沥青里面，在较长时间段内均未出现飞散以及损坏现象，显著提升了道路的耐久性。
