Description

At present, a Marshall standard compaction method is adopted in China to prepare an asphalt mixture test piece, so that a physical and mechanical property test of the asphalt mixture is carried out. The specification of the test procedure of asphalt and asphalt mixtures for highways (JTG E20-2011) prescribes that asphalt mixtures of different compounding types need to be subjected to Marshall compaction test at a specific temperature, and the compaction temperatures of asphalt mixtures of the same type are different, so that the physical and mechanical properties of test pieces are obviously affected, and particularly the void ratio and compactness of the asphalt mixtures are difficult to control.
The existing method for measuring the molding temperature of the Marshall test piece of the asphalt mixture is to put the mixed mixture into an oven for preserving heat for a certain time, put the mixture into a test mold which is preserved in advance, insert the mixture into a thermometer to the vicinity of the center of the mixture after the mixture is inserted and tamped for a specified number of times, and carry out Marshall compaction test after the mixture meets the compaction temperature.
However, during actual operation, compaction temperatures are not readily controlled, the main reasons including: (1) The heating mode of the oven is heating by the electric heating wires, the temperature distribution in the oven is uneven, and the digital display temperature and the actual temperature are difficult to control. (2) Meanwhile, under the influence of factors such as too slow charging speed, too long temperature measuring time or too low room temperature, the material temperature is scattered too fast, the central temperature of the asphalt mixture in the Marshall test die reaches the compaction temperature, but the upper layer, the bottom layer and the part close to the test die of the asphalt mixture are already lower than the compaction temperature, and the temperature of the upper surface of the asphalt mixture is measured to be possibly even lower than the central temperature by more than 20 ℃. (3) On the other hand, asphalt mixture has certain viscosity, and the asphalt mixture adheres to a container to cause quality loss, and the temperature and quality of the mixture are strictly controlled in the test, so that the temperature loss and the quality inaccuracy of the mixture can be caused by different degrees of simple charging containers such as iron sheets, paperboards and funnels commonly used in the laboratory at present, and the test result is influenced.
