City of Ramsey <br />Project B1705491 <br />August 11, 2017 <br />Page 3 <br />B. Results <br />B.1. Exploration Logs <br />B.1.a. Log of Boring Sheets <br />Log of Boring sheets for our penetration test borings are included in the Appendix. The logs identify and <br />describe the geologic materials that were penetrated, and present the results of penetration resistance <br />tests, laboratory tests performed on penetration test samples retrieved from them and groundwater <br />measurements. <br />Strata boundaries were inferred from changes in the penetration test samples and the auger cuttings. <br />Because sampling was not performed continuously, the strata boundary depths are only approximate. <br />The boundary depths likely vary away from the boring locations, and the boundaries themselves may <br />also occur as gradual rather than abrupt transitions. <br />B.1.b. Geologic Origins <br />Geologic origins assigned to the materials shown on the logs and referenced within this report were <br />based on: (1) a review of the background information and reference documents cited above, (2) visual <br />classification of the various geologic material samples retrieved during the course of our subsurface <br />exploration, (3) penetration resistance testing performed for the project, (4) laboratory test results and <br />(5) available common knowledge of the geologic processes and environments that have impacted the <br />site and surrounding area in the past. <br />B.2. Geologic Profile <br />B.2.a. Pavement Materials <br />The borings first encountered an average bituminous pavement thickness of 4.3 inches as shown in <br />Table 2. The aggregate base averaged 7.5 inches. <br />BRAUN <br />INIE=RItC <br />
