1. - Recommended test sample size is approximately 40 times the top-size weight ≈ 16,000 pounds.
2. - 100% of the sample will be finer by weight than the heaviest individual stone weight plus one pound. Heaviest weight plus one will be plotted on the 100% Finer by Weight line of ENG Form 4055 - RIPRAP GRADATION CURVES. The totaled weights of all columns A - G should equal the initial test sample weight “X”.
3. - The Cumulative Percent Finer By Weight number for each column is plotted on ENG Form 4055 - RIPRAP GRADATION CURVES chart, on the weight increment line of the next column's weight range low number, i.e. column B cumulative percent would be plotted on the 30 pound line of the 4055 chart.
