Using just asphalt, as in hot mix, the percentage would be . For emulsions you should check with supplier, but the range is typically 55-70% asphalt. weight asphalt (lbs) = gallons asphalt emulsion per ton * 9.4 lbs/gal * %asphalt in emulsion. The total weight of the mix is the weight of the asphalt plus the weight of the stone (aggregate).
