Abstract: In order to promote low-carbon construction of highway engineering, we have conducted a strategic analysis on the development direction of economically durable asphalt pavement.This article conducts relevant analysis around the rational design of asphalt layered pavement system.Through the analysis of the impact of pavement forces, the functional requirement of each structural layer is analyzed, and more reasonable mixture types and structural layer thickness are matched to achieve the purpose of increasing pavement durability and reducing maintenance costs.It is a way to approach "carbon emissions to peak" at the design stage.The research results indicate that when designing the middle surface layer of asphalt concrete pavement, high modulus asphalt mixture can be selected while increasing the thickness appropriately (not exceeding 8 cm).When designing the lower layer of asphalt concrete pavement, asphalt mixture with lower modulus and smaller nominal maximum particle size can be selected while increasing the thickness.
