Geotechnical Report of Subsurface Investigation LA3642 SCE LAVETA SUB CS (LA23642A) Job Number: 24125796 April 29, 2024│4 Fill Material Types Soil Type USCS Classification Acceptable Parameters (for Structural Fill) Imported Low- to Moderate- Plasticity Soil 2 CL, ML, SC or SM All locations and elevations Sand / Gravel with greater than 12% fines GW/GP, SW/SP Crushed stone base course may be used for the access roadway or beneath shallow foundations as a replacement material for overexcavated soils. Near-Surface On-site soils 2 SM On-site soils generally appear suitable for use as fill when they contain at least 12% fines (clay and/or silt) and are compacted at an appropriate moisture content. 1. Controlled, compacted fill should consist of approved materials that are free of organic matter and debris. A sample of each material type should be submitted to the geotechnical engineer for evaluation. 2. Low- to moderate-plasticity cohesive soil or granular soil having at least 12% fines Fill Compaction Requirements Item Structural Fill General Fill Maximum Lift Thickness 8 inches or less in loose thickness when heavy, self- propelled compaction equipment is used Same as Structural fill Minimum Compaction Requirements 1, 2 98% of max. below foundations and within 1 foot of finished pavement subgrade 95% of max. above foundations, below floor slabs, and more than 1 foot below finished pavement subgrade 92% of max. Water Content Range 1 Low plasticity cohesive: -2% to +3% of optimum High plasticity cohesive: 0 to +4% of optimum Granular: -3% to +3% of optimum As required to achieve min. compaction requirements 1. Maximum density and optimum water content as determined by the standard Proctor test (ASTM D 698). 2. High plasticity cohesive fill should not be compacted to more than 100% of standard Proctor maximum dry density. 2210 3%4 N Grand Ave Unit# WCC01 - 1011184045/30/2024
