摘　　要：沥青路面从建设期到运营期结束的各个阶段都会消耗大量资源和能源,产生各类环境影响问题,而借助生命周期评价方法可以系统分析沥青路面所带来的各类环境负担。因此,以沥青路面生命周期评价方法体系为研究基础,提出基于实验室测试结果和仿真指标的沥青路面运维期环境影响表征,从而系统分析沥青路面生命周期中不同沥青路面材料性能差异所造成的环境影响。同时,对典型沥青路面和某一橡胶沥青路面在运维期和全生命周期的环境影响进行了对比分析。结果表明:仅考虑路面建设期时,典型沥青路面的环境影响小于橡胶沥青路面;而考虑建设期到运维全过程时,橡胶沥青路面的环境影响则小于典型沥青路面。该研究为未来沥青路面结构的“环境+性能”综合评价奠定了理论研究基础。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 impact 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 environmental 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 foundation for the comprehensive evaluation of the"environment+performance"of asphalt pavement structures in future.
