I <br />J <br />l <br />APPENDD( C <br />LABORATORY TESTING <br />Laboratow Testinq Proqram <br />Laboratory tests were performed on representative soil samples to determine their relative <br />engineering propenies. Tests were performed in accordance with test methods ofthe <br />American Society for Testing Materials or other accepted standards. The following <br />presents a brief description ofthe various test methods used. <br />Particle Size Analysis <br />Particle Size Analysis was performed on selected representative samples in accordance <br />with ASTM D-1440. <br />Modified Proctor <br />Laboratory compaction tests were performed according to ASTM D-I557, Method A. A <br />mechanically operated hammer was used during the compaction process. Modified <br />Proctor Analysis curve is presented in Appendix C. <br />1n Situ Moisture <br />The in-place moisture content ofselected samples was determined using relatively <br />undisturbed soil samples. The moisture content is shown on the attached Boring Logs <br />R-Value <br />The resistance "R"-Value was determined by the Califomia Department of <br />Transportation Test Method No. 301 for representative subbase soils. Samples were <br />prepared and exudation pressure and "R"-value determined. The graphically determined <br />"R'-value at exudation pressure of300 psi is the value used for pavement section <br />calculation. <br />Direct Shear Tests <br />Direct shear tests were perlormed on recompacted samples in general accordance with <br />ASTM D-3080-72 to evaluate the shear strenglh characteristics of selected materials. <br />The samples were inundated during shearing to represent adverse field conditions. <br />ulfate Corro <br />These tests were performed on soil samples in order to determine the amount of exposure <br />of sulfates, pH and corrosive materials. High amounts ofeach can have a deleterious <br />effect on the overall performance ofthe concrete or steel used in the foundation ofa <br />building. <br />I <br />l <br />l <br />Classification <br />Soils were classified visually according to the Unified Soil Classification System. Visual <br />classifications were supplemented by laboratory testing ofthe selected samples in <br />accordance with ASTM D-2487 . The soil classifications are shown on the Exploration <br />Boring Logs in Appendix B.
