The following extracts were also taken from the Newfields Report of December 9, 2016: <br /> Direct shear tests were run in an 8-inch square shear box under saturated conditions. To <br /> comply with ASTM D3080 test standards that provide guidance on maximum particle size as a <br /> function of the shear box size, only minus 3/-inch material was used for the test. Results of the <br /> laboratory tests are summarized in Table 1.1. <br /> Table 1.1 <br /> Summary of Material Properties <br /> Sample ID % % % USCS Group Friction Angle Cohesion <br /> Gravel Sand Fines Symbol (deg) (psf) <br /> Overburden 58.8 33.9 7.3 GP-GM 41.4 361 <br /> Colluvium 67.6 23.7 8.7 GP-GM 40.1 0 <br /> As a significant portion of the larger, gravel-sized particles are removed from the test <br /> specimens, the reported shear strengths are considered a conservative estimate and in-place <br /> materials at the ECOSA are likely more competent. <br /> 14 <br />
