Abstract:
In order to solve the problems in the process of Chinas green road construction, such as inconsistent construction concepts and incomplete evaluation systems. The development of the green road concept in China systematically was reviewed. The basic idea of greenroad construction, integrates the greenroad concept was clarified, and the construction of green roads with the theme of green, landscape, ecology, energy savings, and low carbon for more than 80 green roads in China were investigated, as well as green roads abroad. A summary and analysis of the characteristics of green road in China were presented. Then, suggestions for green road construction in special areas were put forward. Based on the crucial technical indicators of green road construction, the technical requirements for evaluating a green road under at present stage were put forward. The evaluation indices system of green roads was set up from 7 aspects, such as green concept, ecological protection, resource conservation, energysaving and lowcarbon, safety and intelligence, service improvement, and quality construction. This evaluation indices system included 7 types of primary assessments 22 secondary indicators and 58 assessments. In this research, the green road nonevaluation indicators under different regional natural environments and construction conditions were defined, and the corresponding weights of the evaluation indicators and the green road evaluation score calculation method were determined. Meanwhile, the evaluation indices system was applied to evaluate a green road in China. The results show that the green road evaluation indices system can completely cover the indicators involved in the highway to be evaluated and has a strong scientific basis and applicability. The total score of the green road is 64.06 points, the green road falls short in resource conservation and service improvement. The green road evaluation indices system provides guidance for construction of Chinas green road, and can provide reference for the sustainable development of Chinas green highways. 6 tabs, 26 refs.
