[0033] The manufacturing method of the high-strength waterproof colored pavement structure is:

[0034] Step 1: First, clean the asphalt pavement 1 and use a fan to blow away the dust in the cracks of the asphalt pavement 1, then spread aggregate on the upper surface of the asphalt pavement 1. The spreading amount of the anti-skid layer 2 is 2-4kg / m 2 The anti-skid layer 2 can improve the wear resistance and anti-skid property of the road surface, thereby ensuring the driving safety of the driver;
