Description

technical field [0001] The invention relates to an MA asphalt mixture stirring device, in particular to a temperature-controlled MA asphalt mixture stirring device. Background technique [0002] At present, the existing mixing device in the asphalt mixture laboratory has many shortcomings, such as: the capacity of the mixing pot is small, the top is open, and it is difficult to ensure the high temperature environment of 200 ° C ~ 240 ° C for long time mixing; the amount of mixing at one time is small , It is difficult to maintain a good contrast with the asphalt concrete mixed many times; the open mixing pot, the asphalt concrete and air exchange, the aging effect is accelerated. The experimental research of MA asphalt mixture cannot be completed with this equipment. At the same time, due to the large output of the asphalt mixing plant and the relatively small test amount, it is not economical to use the asphalt mixing plant to produce MA asphalt mixture for testing. Con...

AI Technical Summary

Problems solved by technology

[0002] At present, there are many shortcomings in the existing mixing device in the asphalt mixture laboratory, such as: the mixing pot has a small capacity and the opening is open, so it is difficult to mix for a long time Guarantee the high temperature environment of 200℃~240℃; the amount of mixing at one time is small, and it is difficult to maintain a good contrast for the asphalt concrete mixed many times; the open mixing pot, the asphalt concrete and air exchange, the aging effect is accelerated

Experimental research on MA asphalt mixture cannot be completed with this equipment

At the same time, due to the large output of the asphalt mixing plant and the relatively small amount of the test, it is not economical to use the asphalt mixing plant to produce the MA asphalt mixture for the test.
