Soil Stabilization (Lime / Cement) Quantity
Lime or cement takeoff for subgrade stabilization from a percent-by-dry-weight mix design: spread (lb/sy) = percent/100 x density x depth/12 x 9; tons = spread x area / 2000. A 6% lime treatment 8 in deep in 110 pcf soil is 39.6 lb/sy, so a 10,000 sy pad needs 198 tons; a 4% cement treatment is 26.4 lb/sy and 132 tons. The geotech's mix design sets the percent - lime for plastic clays, cement for granular subgrades.
Formula and source
spread_lb_per_sy = application_pct/100 x soil_density_pcf x (depth_in/12) x 9; tons = spread_lb_per_sy x area_sy / 2000.
Stabilizer-quantity identity by name (spread from percent x density x depth; tons from spread x area); first-principles takeoff arithmetic.
