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.
