Step 2: Proceed to step 4 if the base soil contains no gravel (material larger than No. 4 sieve). Step 3: Prepare adjusted gradation curves for base soils that have particles larger than the No. 4 (4.75 mm) sieve. • Obtain a correction factor by dividing 100 by the percent passing the No. 4 (4.75 mm) sieve. • Multiply the percentage passing
