COMPOSITIONS AND PAVEMENT CONSTRUCTION METHODS FOR SEMI-RIGID PAVEMENTS USING RECLAIMED ASPHALT CONCRETES

摘要

Semi-rigid packaging composition utilizing the waste ascon of the present invention is a pulverized waste ascon, which provides flexibility, cement and sand to provide rigidity, index agent to prevent the rapid evaporation of water, volume expander to compensate for shrinkage of cement, packaging And a solid admixture composed of an ionic curing accelerator for shortening the curing time and a fluid admixture which coats the solid and imparts fluidity, adhesion and elasticity. As the packaging method , the composition ratio of the composition is determined, and the solid composition is first put into the mixing equipment in the field, dried at room temperature, and then the amount of the fluidized admixture is added and remixed to prepare a coating mixture. The coating surface is first sprayed onto the construction surface, and then the coating mixture is laid with a finisher before the coating liquid dries, and the pile is compacted to a desired density by a combination of compaction rollers. Lightly spray the spray on the compacted surface to cover the cover and cured for 2 to 48 hours, and then walk the cover is characterized in that open traffic.
