Research on Evaluation Index System of Green Highway in Reconstruction and Expansion Projects

This study summarizes and condenses the core requirements of green road construction in the reconstruction and expansion project, systematically analyzes the three typical representative green road evaluation index systems of GreenRoads, INVEST and Green-LITES. A green highway evaluation index system including 7 first-level indicators, 20 second-level indicators, and 52 third-level indicators has been constructed, The analytic hierarchy process was used to establish a step-level model, the relative importance of each index is determined according to the judgment of experts, and the weight coefficient of each level of index is obtained. In terms of policy requirements, related technology applications, green highway development trends, and the actual construction of the Beijing-Shanghai Expressway reconstruction and expansion project, the three-level indicator scoring method was determined. The green highway evaluation index system and evaluation model were used to evaluate the reconstruction and expansion project of the Beijing-Shanghai Expressway from Laiwu to Linyi (Lu-Sujie). It was determined that the comprehensive score of the project was 81.2, which reaching an excellent level.
