Mao <br /> soil test borings were drilled to depths of approximately 18 feet below the <br /> shoulder of the road, approximately 3 feet from the pavement, with a CAE 55 <br /> truck mounted drill rig. The borings were drilled on <br /> g the north side of the <br /> highway, approximately 5 feet fran our original test <br /> evaluate roc-like Loring B-1B4, to <br /> conditions repotted during installation of the bore and <br /> jack. We understand the bore and jack operation proceeded from the south end <br /> of the crossing, and rock-like materials were <br /> two-thirds to three- encountered approximately of the way across the pavement. <br /> Records of recent borings, B-2 and B-2, are attached to this <br /> report to verify that partially weathered rock materials do <br /> pardon of the bore and jack crossing at depths on the underlay a <br /> beneath the order of 11 to 12 feet <br /> slx alder of the road. Neither of our previols borings, B-184 or <br /> B-135, indicated the presence of partially weathered rock, <br /> materials defined as <br /> exhibiting standard penetration resistance values in excess of 100 <br /> blows per foot, at the test boring locations. However, subsurface conditions <br /> can vary within relatively short lateral distances due to lithologi.cal <br /> S&ME,Inc. <br /> 3109 Spring Forest Rd., P.O.box 58069 <br /> Raleigh, NC 27658-8069(919)872-2660 <br />
