In laboratory test, the temperature of test equipment has an influence on test result of asphalt mix- ture. Through the supervision of related equipment during test, the temperature deviation of devices such as calor- stat and mixing pot as well as solutions are proposed. Through the test, the operating temperature of related equip- ment in the test process of various type of modified asphalt is obtained and operation asphalt mixture such as base asphalt, Sasobit modified asphalt, and SBS details needing attention in the test process, such as mixing and sticking ＆ mashing are obtained as well. The test results show that the actual temperature in calorstat is higher than set tem- perature ; the temperature of aggregate is lower than set temperature in calorstat about 8℃ ; the average temperature in mixing pot is lower than set temperature 12℃ ; the temperature measured by infrared thermometer needs to be adjusted and compared with that by thermometer; the tester needs to be fast and skilled in the test.
