Calculation: 1. Total percentage of moisture in an oven dry basis: Wet Wt – Dry Wt % Moisture Oven Dry Basis = x 100% Dry Wt. Wet Wt = original weight (mass) of aggregate Dry Wt = oven dry weight (mass) of aggregate 2. Calculate the percent surface (free) moisture: % Surface moisture = (% Moisture, Oven Dry Basis) - (% Absorption, from Mix Design
