The invention discloses a device for detecting the seepage degree of wax oil in asphalt and a detection method, and relates to the field of asphalt material detection. Comprising a pneumatic pump and a constant-temperature heater, the bottom end of the pressure box is connected with a plurality of sample testing assemblies; and the plurality of sample testing assemblies are respectively connected with the constant-temperature heater. The pressure box is connected with the plurality of sample testing assemblies, the pneumatic pump pressurizes all the sample testing assemblies at the same time, and then the constant-temperature heater heats the sample testing assemblies at a constant temperature, so that the pressure and the environment temperature of asphalt in the actual use process are simulated, and the oil seepage degree of the asphalt is detected. The research on the oil seepage characteristic of the asphalt material under the long-term use condition is perfected; the number of the infected standard doubl
