Study on New Treatment Technology of Subgrade Longitudinal Crack in Qinghai-Tibet Highway

Abstract:

Longitudinal crack is one of the main subgrade diseases of qinghai-tibet highway and has large scale.While the existing treatment technology cannot completely solve the problem,especially cannot limit crack propagation,so the driving safety and road life will have huge influenced by the disease.In order to solve this problem,a new solution technology that the flexible beam combined with tenon type geomembrane bag is proposed in this paper.Through field implement,this new method which can effectively reduce and prevent crack diseases is verified.
