Method and device for evaluating carbon emission behavior and attenuation law of asphalt mixture

The invention provides a hot-mix asphalt mixture carbon emission behavior and attenuation law evaluation method and device. The method comprises the following steps: construction and pre-operation of a test environment; preparing and storing an asphalt mixture; preparing a carbon emission test; reading and collecting test data; and drawing a correlation graph of different carbon emission data, test time and environment temperature based on the obtained data, calculating a reference emission difference number envelope area and an evaluation index, and determining a carbon emission behavior and an attenuation rule. The method is suitable for evaluating the carbon emission behavior of different types of hot-mixed or warm-mixed asphalt mixtures in road engineering, can accurately evaluate and estimate the carbon emission and attenuation law of the mixed asphalt mixtures, and can also be used as an effective basis for evaluating the carbon emission; the carbon emission accounting accuracy of road engineering const
