1. OUTPUT ABILITY
Mix 600 kg asphalt each batch
If average moisture content of sand is 5%, and mixing period is 40s, output is 48T/H
If average moisture content of sand is 5%, and mixing period is 60s, output is 36T/H.
Conditions concerned with output ability are as follows
1) Moisture content of sand only refers the surface moisture content of material, and moisture content inside will low the output ability of drying drum.
2) Ambient humidity is 20℃.
3) Density of the material is 1600 kg/m³.
4) Output includes the weight filler and bitumen.
5) The proportion of aggregate must be correctly, and the specifications must fit to standard.
6) The density of filler is 1120 kg/ m³.
