Abstract
Fully utilizing road waste materials in rural road construction and maintenance is of great significance for promoting the transformation of rural road construction towards green,low-carbon,and sustainable direction.By establishing a platform for the collection,storage and utilization of waste and old pavement materials,the unit applies the plant mixed hot recycled asphalt concrete process to the middle and lower layers of long-life pavement,uses geopolymer gel and waste cement aggregates or ordinary soil to make base or subbase,and carries out operations based on the principle of aluminosilicate mineral polymerization reaction.The use of waste asphalt concrete in the middle and lower layers of long-life pavement can significantly extend the design service life,significantly improve the performance,and reduce resource consumption and cost.The application of geopolymer gel in the base course can ensure strength and stability and reduce ore mining.The application of road waste materials in rural road construction and maintenance is feasible,providing new ideas for material utilization in rural road construction.关键词
