Calculate the feed rate in tons per hour (tph) for a drummix asphalt plant under the following conditions:

Asphalt content = 5%

Aggregate composition:

Coarse A = 45%

Coarse B = 30%

Sand = 20%

Mineral filler = 5%

Field moisture content of gravel and sand = 6%
Drum capacity at required moisture removal = 138 tph (125 t/h)
