Abstract

The invention relates to a high grade road surface double layer micro-process and the construction method. The construction water proof layer is laid on the road surface, and a skid resistance wearing coat is laid on the construction water proof layer. The amounts by weight or volume of water proof layer is that: aggregate is 100; polymer modification positive ion emulsified asphalt is 8 to 16; water is 6 to 11; Portland cement or slaked lime is 1 to 4; and additive is 0.1 to 0.5. The amounts by weight of skid resistance wearing coat is that: aggregate is 100; polymer modification positive ion emulsified asphalt is 6 to 11; water is 7 to 13; Portland cement or slaked lime is 1 to 3; and additive is 0.1 to 0.5. The construction process is the following steps: cleaning the road surface, laying out, laying water proof layer, laying skid resistance wearing coat, early days conserving and quality checking out. The invention is reasonable designed, good performance of water proof, and fast moulding.

Description

technical field

[0001] The invention belongs to the technical field of coagulating pavement paved on site for roads or airports, in particular to a pavement paved on site with several layers of different materials. Background technique

[0002] Slurry seal layer is a pavement with a certain thickness formed by mixing emulsified asphalt, graded mineral materials, fillers, water and additives in a certain proportion into a paste-like flow mixture under normal temperature conditions, and paving it on the road surface in time. The thin layer plays the role of waterproof, anti-slip, wear-resistant and restores the function of the road surface. It is mainly used for the maintenance of the asphalt pavement of ordinary roads. Currently, it is less used in the maintenance of the asphalt pavement of the expressway. This kind of sealing layer can improve the water resistance and anti-skid performance of the road surface. According to the maximum particle size of the aggregate in the sl...
