A normal load of 2,000 psf was used for the <br /> middle point of each test to simulate the midpoint of an approximate forty foot high <br /> embankment. The angle of internal friction determined for each of the materials tested is <br /> described below: <br /> Location Description Friction Angle <br /> Combined borings 5 and 9 SAND,with occasional gravel 35.60 <br /> E <br /> Combined borings 7 and 10 SAND, with gravel 33.2° <br /> Combined borings 4, 5 and 12 SAND, gravelly 45.10 <br /> If you have any questions on the data presented,please contact us at your convenience. <br /> Sincerely, Reviewed by: <br /> WesTest WesTest <br /> Zachary Wheeler, EIT Eric R West, P.E. <br /> AMR <br /> MSHTOR18 <br />
