This is a laboratory test report package documenting soil analysis for a project location identified as 18-CL2 at the Melrose Range. The testing was conducted by Lydick Engineers & Surveyors, Inc. on January 9, 2018, with results checked by Robert C Lydick PE & LS.

The report contains four separate test analyses on a caliche base sample (SNP material): liquid and plastic limits testing, grain size distribution testing, and particle size distribution analysis. Key findings include a liquid limit of 43.0%, plastic limit of 17.6%, and a fines content of 17.6% passing the #200 sieve. Grain size distribution data shows 25.6% gravel (fine), 43.3% sand (coarse, medium, and fine combined), 17.6% fines (silt and clay), with a fineness modulus of 3.65. The particle size distribution report classifies the material as CALICHE BASE SNP per AASHTO (M 145) standards, with D90 coefficient of 21.4761 mm. All testing data is presented in tabular format with accompanying charts and graphs showing the distribution curves and moisture content relationships. The material classification and test results are consistent across all analyses, confirming the sample characteristics for the Melrose Range project site.
