Environmental Impact Evaluation of Asphalt Pavement Considering Service Performance Differences
From the construction period to the end of the operation period,asphalt pavement consumes a large amount of resources and energy,resulting in various environmental impact problems.The various environmental burdens caused by asphalt pavement can be systematically analyzed by life cycle assessment methods.Therefore,based on the life cycle evaluation method system of asphalt pavement,a characterization of the environmental im-pact of asphalt pavement during operation and maintenance period based on laboratory test results and simulation indicators is proposed to systematically analyze the environmental impact caused by the performance differences of different asphalt pavement materials.At the same time,a comparative analysis was conducted on the environmental impact of typical asphalt pavement and a certain rubber asphalt pavement during the operation and maintenance pe-riod and the entire life cycle.The results show that the environmental impact of typical asphalt pavement is smaller than that of rubber asphalt pavement when only the road construction period was considered;However,the environ-mental impact of rubber asphalt pavement is smaller than that of typical asphalt pavement when the entire process from construction to operation and maintenance was considered.This study provides a theoretical research founda-tion for the comprehensive evaluation of the"environment+performance"of asphalt pavement structures in future.
