Asphalt pavement full life cycle environmental influence evaluation method

Abstract

The invention discloses an asphalt pavement full life cycle environmental impact evaluation method, which comprises the following steps of: determining a consumption and emission list of an asphalt pavement in a full life cycle under a function unit on the basis of energy background data based on a process list analysis method; determining the environmental influence type in the full life cycle of the asphalt pavement, and quantitatively describing the consumption and emission list data as a corresponding environmental influence potential value through a characterization factor; the equivalent GDP environmental influence potential value in China in 2018 is adopted as a standardized reference value, and the environmental influence potential value is subjected to standardized processing; and based on a policy target distance method, determining weight factor values of all environmental influence types in the life cycle of the asphalt pavement, and finally performing weighted summation to obtain an environmental influence comprehensive value of the asphalt pavement in the whole life cycle. The environmental influence type weight factors are determined based on the target distance method, combination of the weight factors and policies is enhanced, subjectivity of an evaluation system is enhanced, and evaluation and decision making of the scheme are facilitated.

Description

technical field [0001] The invention belongs to the field of asphalt pavement and life cycle assessment, and relates to a method for assessing the environmental impact of the entire life cycle of asphalt pavement. Background technique [0002] my country's highway construction industry is developing rapidly, and the total mileage of highways currently ranks first in the world. Among them, asphalt pavement has been widely used due to its short construction period, good driving conditions, and renewable utilization, which effectively promotes the formation of my country's highway traffic network. , promoted the rapid development of social economy. However, the project volume of asphalt pavement is huge, and the pollution emission problem caused by large-scale paving cannot be ignored. With the implementation of the traffic power policy, the asphalt pavement, which constitutes the main body of the national expressway network, will undoubtedly become the key object of energy con...
