  • Patent number: 12216108
    Abstract: An evaluation method for ecological performance of an asphalt-related material is provided. Firstly, working condition parameters are determined for evaluating the ecological performance of the asphalt-related material; secondly, based on the working condition parameters, a simulation test is performed on emission of asphalt-related pollutants during a preparation stage of the asphalt-related material; finally, based on a result of the simulation test, a quantitative evaluation of the ecological performance of the asphalt-related material is performed under different environmental impacts. The evaluation method is a laboratory scale simulation method based on measured pollutant emissions and various environmental impact factors, ultimately achieving laboratory scale ecological performance evaluation of the asphalt-related material, which has important reference value for green material selection of asphalt pavement.
