Research on Construction Method of Mountain Highway Reconstruction and Expansion Project Based on Subgrade Pavement Widening Processing Technology
Due to the complex construction environment of mountain highway reconstruction and expansion project,the construction progress is affected,the traffic and the project interfere with each other.Based on the finite element analysis of highway pavement reconstruction and expansion based on subgrade pavement widening processing technology,considering the distribution of pavement tensile stress,this paper proposes a construction method for mountain highway reconstruction and expansion project based on subgrade pavement widening processing technology.New pavement surface material is selected and the subgrade on both sides is widened to complete the construction process of highway reconstruction and expansion.The experimental results show that,when the improved construction method is used,the pavement deformation deviation at each measurement point is lower than the maximum allowable deviation of construction,indicating that the construction effect of this method is relatively good.
