Concrete bridge deck top 8 ㎝ durability of asphalt paving drainage method

摘要

The present invention relates to a kind of construction methods of durable drainage asphalt pavement, to 8 centimetres of deck paving of concrete upper layer. Purposes of the invention is using drainage asphalt pavement to bridge deck paving with 8 centimetres of thickness and solve the problems, such as early damage bridge surface waterproof layer and screed-coat. This purpose be embodied as asphalt contain composite adhesives (MG) modified oil pitch and bitumen substitution waterproof layer lower end from the upper layer of 8 centimetres of Bridge Surface Paving by Cement, and be configured to a thickness of 3 binding force improve drainage asphalt pavement to upper layer. The object of the invention this can be implemented so that the maximum particle diameter of the synthetic binder (MG) of partial size asphalt containing modified oil pitch and above-mentioned bitumen is 13 millimeters, and wherein the ratio of fine aggregate accounts for 60-95%; The mixture produces and pavement temperature range is 200-260 degrees Celsius; And drainage index paves and constructs and constructing between 52 degrees Celsius and 68 degrees Celsius in surface temperature. ;The 2015 of copyright KIPO submissions
