The utility model relates to a material weighing and pouring temperature-sensing barrel for a Marshall testing die. The material weighing and pouring temperature-sensing barrel comprises a barrel, wherein a material pouring hole is formed in the bottom wall of the barrel, a thermostat probe is arranged on the inner surface of the barrel, and a temperature display device connected with the thermostat probe is arranged on the outer surface of the barrel; the diameter of the material pouring hole is less than the inner diameter of the Marshall testing die, and a material pouring hole cover plate with the size greater than the material pouring hole covers the material pouring hole. Mixed materials are arranged in the barrel to be weighed, the temperature of the mixed materials can be effectively measured in real time through the arranged digital thermometer probe and the temperature display device, and experimental accidental errors caused by overlow temperature of the mixed material can be reduced; by setting the diameter of the material pouring hole to be less than the inner diameter of the Marshall testing die, material pouring can be fast completed by the material pouring hole and a Marshall testing die opening, the material weighing and pouring temperature-sensing barrel is simple in structure, and reasonable in design, integrates material weighing, pouring and temperature measurement as a whole, the operation steps can be effectively simplified, the time can be saved, and the efficiency can be accelerated.
