Check the quality and uniformity of various materials from the material pile and conveyor at any time, check the mud and fine-grained gravel, and check whether there is a leak in the cold silo. Check whether the mixture is evenly mixed and there is no leakage. There is no speckling material, whether the whetstone ratio is valid, and check the concrete segregation of aggregates and mixtures.

Check the preset values ? of various main parameters of the mixer in the control room and the displayed values ? on the control screen. Check whether the statistics and displayed values ? described on the computer and copy are consistent. Check the material heating temperature of the asphalt mixture and the mixture entry temperature. 
The staff of the asphalt mixing plants should cooperate with the staff of the laboratory to make timely adjustments to the asphalt plant based on the results of the laboratory test results, so that the mixture gradation, temperature, and oil-stone ratio are within the specified operating range. The production temperature of the asphalt mixture should comply with the construction temperature requirements of hot mix concrete. The residual moisture content of the air-dried aggregate should not exceed 1%. The heating temperature should be increased for the first two trays of aggregate every day, and several pots of dry mixing should be performed. The aggregate waste is then added to the asphalt mix.
The mixing time of asphalt mixture should be based on the detailed conditions
