(1)Environment temperature: 20°C,standard atmospheric pressure; Local altitude should be less than 2000m;
(2)The average humidity of Cold aggregate <5%
(3)The temperature of the hot asphalt mixture <160°C
(4)The mixture is middle size, cycle time 45S, the density of stone material in the mixture≥1600kg/m3
(5)The content of fine aggregate in mixture <35%;

(6) The filler proportion in the raw aggregate material should not higher than 3%.
(7)The cold aggregate must be clean, and it shouldn't include more soil and sundries. The cold aggregate supply should be continuous.
(8)The cold aggregate shouldn't include large quantity of oversize grain; otherwise it will cause jam and reduce the aggregate supply
capability.
(9)The water content in filler material should < 0.5%, and the filler shouldn't have conglomeration, agglomeration, otherwise it will
cause material supply break and time delay accordingly influence the capacity.
(10)The asphalt should be with well wrapping capability, during standard mixing circle, the aggregate should be completely
