机场绕滑道工程高性能沥青混合料研究与应用

摘要:

依托虹桥机场绕滑道系统安全改造项目,研究不同品种、不同掺量高模量剂对SMA-13和AC-20混合料动稳定度的影响,根据虹桥机场绕滑道现场条件及未来使用需求,比选并确定适用于新建绕滑道道面沥青面层的最优高模量剂与掺量。基于室内试验对沥青道面的混合料性能进行分析,结果表明所选用高性能沥青混合料具有优异的高温稳定性、耐疲劳性能、抗水损害性能,能有效满足绕滑道道面运营使用需求。最后结合工程实际施工效果进行评价。

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.
