In order to improve the long-term performance of pavement structure, from the point of view of increasing the modulus of the structural layer, the influence of the modulus of the medium layer on the long-term performance of pavement structure was analysed through mechanical simulation.Then the structural reinforcement scheme of pavement was draw up, and compared with the original pavement structure scheme. Furthermore, combining with the physical engineering, the feasibility of the scheme was demonstrated. Finally, the results show that, by increasing the modulus of mid-surface layer, the anti-rutting and anti-fatigue performance of pavement structure was improved. And through the post-construction test, the pavement performance of the test road, which was implemented by structural reinforcement technology, was proved to be in good condition. Also, the scheme of improve the long-term performance of pavement structure by increasing the modulus of mid-surface layer was confirmed to be feasible.
