1. Based on following soil parameters, determine the average cement required for a sandy soil: Material retained on No.4 sieve (%) = 20% Material smaller than 0.05 mm (%) = 24% Anticipated Maximum Dry Density (pcf) = 129 pcf Hint: use Table 9.8 from Soil Stabilization for Roads and Airfields --L3
Table 9-8. Average cement requirements for granular and sandy soils. Cement Content, Percent by Weight Maximum Dry Density, Ib/cu ft (Treated Material) Material Retained on No 4 Sieve, Percent Material Smaller Than 0.05 mm, Percent 116-120 121-126 127-131 132-137 138-142 143 or more 5 8 5 778-668 8 0-19 10 9 8 0-14 20-39 7 40-50 11 10 9 0-19 10 15-29 20-39 9 7 40-50 12 10 9 0-19 10 8 7 30-45 20-39 11 40-50 12 11 10 Note: Base course goes to 70 percent retained on the No 4 sieve. 8 6 5 6 5 6 7 5 6 8 auuuuuu 5 6 5 5 6 9 6 7 9 8
