Zusammenfassung:The invention discloses a rapid evaluation method for asphalt performance in a full-temperature domain, and relates to the field of asphalt performance evaluation. The method aims at solving the problems that an existing asphalt temperature performance evaluation method is low in evaluation efficiency and large in asphalt consumption. The method comprises the following steps: placing an asphalt sample on a parallel plate of a temperature control device of a dynamic shear rheometer; the diameter of the asphalt sample is 8mm, and the thickness of the asphalt sample is 0.5 mm; based on the asphalt sample, obtaining an asphalt high-temperature performance evaluation index value, and evaluating the high-temperature performance of the asphalt by using the high-temperature performance evaluation index value; based on the asphalt sample, obtaining an asphalt low-temperature hardening resistance index value, and evaluating the asphalt low-temperature hardening resistance; based on the asphalt sample, obtaining an asph
