ISBN:
Category : Geosynthetics
Languages : en
Pages : 166

Book Description
Soil-geosynthetic composites such as those used in mechanically stabilized earth (MSE) retaining walls are experiencing widespread use, particularly in transportation applications. The potential economic benefit of using "lower-quality" on-site material in MSE retaining wall applications is substantial. An experimental research program investigating soil-geosynthetic interaction was performed at the University of North Carolina at Charlotte. To study this composite behavior, the research program employed a large pullout box equipped with state-of-the-art electronic instrumentation and data acquisition. The interaction of two "lower quality" piedmont residual soils (A-2-4 and A-4) with four representative, geosynthetic reinforcement materials (rigid geogrid, flexible geogrid, high strength geotextile, and medium strength geotextile) was examined through a series of anchorage strength tests. Through these tests, insight into the load versus deformation behavior of the reinforcing materials embedded in piedmont residuum was obtained. This report describes the test methodology and presents test results.

The contributions discuss new concepts and innovative solutions, and are concentrated but not limited on the following topics: · Unbound aggregate materials and soil properties · Bound materials characteritics, mechanical properties and testing · Effect of traffic loading · In-situ measurements techniques and monitoring · Structural evaluation · Pavement serviceability condition · Rehabilitation and maintenance issues · Geophysical assessment · Stabilization and reinforcement · Performance modeling · Environmental challenges · Life cycle assessment and sustainability Bearing Capacity of Roads, Railways and Airfields is essential reading for academics and professionals involved or interested in transport infrastructure systems, in particular roads, railways and airfields.

Establishment of Subgrade Undercut Criteria and Performance of Alternative Stabilization Measures

Establishment of Subgrade Undercut Criteria and Performance of Alternative Stabilization Measures PDF Author: Roy H. Borden

Category : Pavements
Languages : en
Pages : 328

Book Description
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.

Handbook of Geotechnical Investigation and Design Tables

Handbook of Geotechnical Investigation and Design Tables PDF Author: Burt G. Look
Publisher: CRC Press
ISBN: 020394660X
Category : Science
Languages : en
Pages : 356

Book Description
This practical handbook of properties for soils and rock contains, in a concise tabular format, the key issues relevant to geotechnical investigations, assessments and designs in common practice. In addition, there are brief notes on the application of the tables. These data tables are compiled for experienced geotechnical professionals who require a reference document to access key information. There is an extensive database of correlations for different applications. The book should provide a useful bridge between soil and rock mechanics theory and its application to practical engineering solutions. The initial chapters deal with the planning of the geotechnical investigation, the classification of the soil and rock properties and some of the more used testing is then covered. Later chapters show the reliability and correlations that are used to convert that data in the interpretative and assessment phase of the project. The final chapters apply some of these concepts to geotechnical design. This book is intended primarily for practicing geotechnical engineers working in investigation, assessment and design, but should provide a useful supplement for postgraduate courses.

Soil Improvement and Ground Modification Methods

Soil Improvement and Ground Modification Methods PDF Author: Peter G. Nicholson
Publisher: Butterworth-Heinemann
ISBN: 0124078990
Category : Technology & Engineering
Languages : en
Pages : 474

Book Description
Written by an author with more than 25 years of field and academic experience, Soil Improvement and Ground Modification Methods explains ground improvement technologies for converting marginal soil into soil that will support all types of structures. Soil improvement is the alteration of any property of a soil to improve its engineering performance. Some sort of soil improvement must happen on every construction site. This combined with rapid urbanization and the industrial growth presents a huge dilemma to providing a solid structure at a competitive price. The perfect guide for new or practicing engineers, this reference covers projects involving soil stabilization and soil admixtures, including utilization of industrial waste and by-products, commercially available soil admixtures, conventional soil improvement techniques, and state-of-the-art testing methods. - Conventional soil improvement techniques and state-of-the-art testing methods - Methods for mitigating or removing the risk of liquefaction in the event of major vibrations - Structural elements for stabilization of new or existing construction industrial waste/by-products, commercially available soil - Innovative techniques for drainage, filtration, dewatering, stabilization of waste, and contaminant control and removal
