Download or read book Establishment of Subgrade Undercut Criteria and Performance of Alternative Stabilization Measures written by Roy H. Borden and published by . This book was released on 2010 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this research includes the development of criteria to define the need for undercutting, the depth of the undercut, and the quality of the backfill material such that the cost and performance are optimized. In addition, chemical stabilization ahd geosynthetics reinforcement, in combination with several thicknesses of the ABC were studied to provide comparative criteria for the enhancement of various poor subgrade soils encountered in N.C. with, or in lieu of, undercut and replacement with select fill. The criteria are presented along with the associated relative costs of each alternative.
Download or read book Proof Rolling of Foundation Soil and Prepared Subgrade During Construction written by Phillip Dunston and published by . This book was released on 2018-02 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 16. AbstractProof rolling provides a method to examine the entire subgrade surface as a compliment to standard random acceptance testing. Proof rolling requires established criteria that account for the interplay of equipment parameters and soil characteristics, technique, and other specifics of the project to allow for proper interpretation. The researchers concluded that proof rolling is not appropriate for determining soil elastic properties, while it can reveal in situ strength properties. No information from state highway agencies (SHA) publications or interviews reports using proof rolling other than for the evaluation of the subgrade. Only eight SHA¿s have notable specifications or other supporting documents containing significant guidance or criteria. The requirements provided for use of either of two equipment types¿tandem-axle rear dump trucks and chariot-style rollers¿and a range of evaluation criteria based on soil type and whether the project is new construction or re-construction. Recommendations provided fall within parameters practiced by states that have the most well-developed specifications and practices for proof rolling. The recommendations include: evaluation is of the subgrade only and the equipment shall be either a tandem-axle rear dump truck or a tri-axle rear dump truck (with raised third axle) loaded to a minimum gross weight of 20 tons. The chariot-style roller loaded to a minimum gross weight of 40 tons could be alternatively specified. The test shall be a single pass in each traffic lane with the passing criteria of a 1¿ deflection for new construction and 1⁄2¿ deflection for re-constructed or stabilized subgrade, as well as the absence of pumping and cracking.

Download or read book Cost effective and Sustainable Road Slope Stabilization and Erosion Control written by Laura Fay and published by Transportation Research Board. This book was released on 2012 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the United States it is estimated that 75 percent of all roads are low volume roads maintained by some 35,000 local agencies. Low volume roads often omit surface slope protection, and this can lead to slope failure, erosion, and maintenance, safety, and ecological issues. This report presents information on cost effective and sustainable road slope stabilization techniques, with a focus on shallow or near surface slope stabilization and related erosion control methods used on low volume roads. To fully address this topic, planning and site investigation are discussed, as well as erosion control techniques, soil bioengineering and biotechnical techniques, mechanical stabilization, and earthwork techniques. Information presented in this report was obtained through an extensive literature review, and from survey and interview responses. From the survey responses, 30 individuals were interviewed based on the information they made available in the survey. A total of 25 interviews were conducted over the phone, and in two cases written responses were received"--Preface.

Book excerpt: Rock Slope Engineering covers the investigation, design, excavation and remediation of man-made rock cuts and natural slopes, primarily for civil engineering applications. It presents design information on structural geology, shear strength of rock and ground water, including weathered rock. Slope design methods are discussed for planar, wedge, circular and toppling failures, including seismic design and numerical analysis. Information is also provided on blasting, slope stabilization, movement monitoring and civil engineering applications. This fifth edition has been extensively up-dated, with new chapters on weathered rock, including shear strength in relation to weathering grades, and seismic design of rock slopes for pseudo-static stability and Newmark displacement. It now includes the use of remote sensing techniques such as LiDAR to monitor slope movement and collect structural geology data. The chapter on numerical analysis has been revised with emphasis on civil applications. The book is written for practitioners working in the fields of transportation, energy and industrial development, and undergraduate and graduate level courses in geological engineering.
