Aggregate Moisture Dry Feed Correction Calculator

Aggregate moisture changes the amount of true stone entering the drum and can distort gradation, binder demand, and burner load. This calculator gives plant operators a quick dry-feed rate from wet tons, runtime, and the dry-solids percentage after moisture is removed.

What this calculator does

  • Convert wet aggregate feed into an effective dry aggregate tons-per-hour rate using measured production time and dry-solids factor.
  • a plant operator or QC technician needs to adjust wet aggregate feed readings after rain, stockpile watering, or changing RAP moisture
  • Returns the effective dry aggregate feed rate after measured aggregate moisture is removed.

Formula used

  • Wet aggregate feed rate = wet aggregate processed ÷ production runtime
  • Corrected dry aggregate feed rate = wet feed rate × dry-solids factor

Inputs explained

  • Aggregate Moisture Correction completed output: undefined
  • Aggregate Moisture Correction runtime: undefined
  • Aggregate Moisture Correction efficiency: undefined

How to use the result

  • Use it when stockpile moisture changes and plant feed, burner demand, or aggregate proportions need a quick correction.
  • It does not replace belt scale calibration, stockpile moisture sampling, RAP binder correction, or full blend-sheet adjustments.

Common questions

  • What is the dry-solids factor? It is the portion of wet aggregate that remains as dry aggregate after water is removed. If measured moisture is 5%, enter 95%.
  • Should I include RAP moisture? Use this calculator for whichever wet feed stream you are correcting. RAP can be checked separately because its moisture and binder credit are usually managed differently from virgin aggregate.
  • Why does moisture correction matter for asphalt mix? Excess moisture lowers true dry aggregate feed, increases dryer energy, and can shift the binder-to-aggregate relationship if not corrected.
  • How should I use the dry tons per hour result? Use it to adjust cold-feed settings, verify plant production rate, and investigate changes in burner fuel use or mix consistency.
