Eastern Washington University’s is currently undergoing construction with the addition of the Interdisciplinary Science Center. A soil sample was collected from the construction site and over the course of Fall Quarter 2018 we performed a series of tests on this soil allowing us to classify the soil based on the Unified Soil Classification System. These tests include: a specific gravity determination test according to the American Society for Testing and Materials (ASTM) standard D854, a sieve and hydrometer analysis according to the ASTM standard D422, and an Atterberg limits test according to the ASTM standard D-4318. We also performed a compaction test according to the ASTM standard D698 in which we determined the soils optimum water content, the maximum dry unit weight, and the allowable range for water content for compaction. We found that the optimum water content for compaction is 16.5%.
