Abstract:SRelying on the safety renovation project of the bypass slide system of Hongqiao Airport, the effect of different varieties and different high modulus agents on the dynamic stability of SMA-13 and AC-20 mixtures was studied. According to the on-site conditions of the bypass slide of Hongqiao Airport and the future Use requirements, compare, select, and determine the optimal high modulus agent and dosage for the newly-built detour pavement asphalt pavement. The performance of the asphalt pavement mixture is analyzed based on indoor tests. The results show that the selected high-performance asphalt mixture has excellent high temperature stability, fatigue resistance, and water damage resistance, and can effectively meet the operational requirements of the bypass slide pavement. Finally, it is evaluated based on the actual construction effect of the project.
