[Abstract]:Highway is the infrastructure of economic and social development. In recent years, with the increasing mileage of traffic, there has been a upsurge in the construction of low-carbon highway in many areas, but how to build low-carbon highway, There are still many problems to be solved urgently how to evaluate the main impact indexes and evaluation methods of the whole life cycle highway carbon. In this paper, according to the road carbon evaluation method, through the analysis of the domestic and foreign research status and consulting a large number of documents, a whole life cycle road carbon evaluation index system is established. For the indexes that can be calculated quantitatively in the index system, by analyzing the influence of every stage of the whole life cycle highway, that is, the period of planning and design, the period of construction, the period of operation, the period of maintenance and maintenance, on the carbon emission of highway, The carbon metering model of the whole life cycle highway is established, and the carbon emission of the whole life cycle road is calculated quantitatively by using the model. For qualitative indicators, the method of expert evaluation is used to quantify the indicators. For the determination of index weight in the whole life cycle road carbon evaluation system, the integrated weighting method based on "function driven" principle and objective weight value method based on "difference drive" principle is adopted. The method of weighting value embodies the information of objective data and subjective information and makes the result of weight determination more reasonable. Because there are a lot of incompatible problems in the whole life cycle highway carbon evaluation project, and the index value is relatively few, so according to the grey matter element model, the information entropy is adopted in this paper. A grey matter-element evaluation model based on information entropy is established by combining grey theory with matter-element theory. According to this model, a life-cycle road carbon evaluation model is established. Because of the complexity of the carbon evaluation model of the whole life cycle highway, the analysis of the evaluation index based on the information entropy is more complicated. So the whole life cycle highway carbon evaluation system is developed by using object-oriented visual programming language Visual Basic.Net. The evaluation system is applied to the Huanghua City Roundabout Project in G307 Bohai Sea New area. Aiming at the difference between asphalt concrete pavement and cement concrete pavement, the carbon evaluation system of the whole life cycle highway is studied. Through the application of the evaluation system, the evaluation model and the evaluation system have great practical value.
