In view of the construction problems in the application process of GMA cast asphalt concrete, based on the summary of the construction technology of GMA cast asphalt pavement layer, the standard construction technology research was carried out, and the standard process of construction preparation, GMA mixing, transportation support and pavement construction was systematically proposed. The standard construction technology of sand blasting, shot blasting, rust removal, waterproof bonding system, mixing, transportation, paving and the problems that need attention in each link were clearly defined. The standard construction technology with reference significance for GMA cast asphalt concrete construction is provided, the construction quality of GMA cast asphalt concrete is improved, and the application difficulty of GMA cast asphalt concrete is further reduced.
