Available in PDF, EPUB and Kindle. Book excerpt: This report addresses four proposed revisions to the AASHTO guidelines concerning design and construction of geosynthetic-reinforced soil (GSR) walls (AASHTO, 1996). The proposed revisions are regarding: lateral earth pressure on wall facing, long-term deformation, truncated reinforcement at wall base and the CTI tails, and embedment and leveling pad.

Book Synopsis Geosynthetic Reinforced Soil (GRS) Walls by : Jonathan T. H. Wu
Download or read book Geosynthetic Reinforced Soil (GRS) Walls written by Jonathan T. H. Wu and published by John Wiley & Sons. This book was released on 2019-05-03 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book to provide a detailed overview of Geosynthetic Reinforced Soil Walls Geosynthetic Reinforced Soil (GRS) Walls deploy horizontal layers of closely spaced tensile inclusion in the fill material to achieve stability of a soil mass. GRS walls are more adaptable to different environmental conditions, more economical, and offer high performance in a wide range of transportation infrastructure applications. This book addresses both GRS and GMSE, with a much stronger emphasis on the former. For completeness, it begins with a review of shear strength of soils and classical earth pressure theories. It then goes on to examine the use of geosynthetics as reinforcement, and followed by the load-deformation behavior of GRS mass as a soil-geosynthetic composite, reinforcing mechanisms of GRS, and GRS walls with different types of facing. Finally, the book finishes by covering design concepts with design examples for different loading and geometric conditions, and the construction of GRS walls, including typical construction procedures and general construction guidelines. The number of GRS walls and abutments built to date is relatively low due to lack of understanding of GRS. While failure rate of GMSE has been estimated to be around 5%, failure of GRS has been found to be practically nil, with studies suggesting many advantages, including a smaller susceptibility to long-term creep and stronger resistance to seismic loads when well-compacted granular fill is employed. Geosynthetic Reinforced Soil (GRS) Walls will serve as an excellent guide or reference for wall projects such as transportation infrastructure—including roadways, bridges, retaining walls, and earth slopes—that are in dire need of repair and replacement in the U.S. and abroad. Covers both GRS and GMSE (MSE with geosynthetics as reinforcement); with much greater emphasis on GRS walls Showcases reinforcing mechanisms, engineering behavior, and design concepts of GRS and includes many step-by-step design examples Features information on typical construction procedures and general construction guidelines Includes hundreds of line drawings and photos Geosynthetic Reinforced Soil (GRS) Walls is an important book for practicing geotechnical engineers and structural engineers, as well as for advanced students of civil, structural, and geotechnical engineering.

Book Synopsis Construction and Monitoring of Post-tensioned Masonry Sound Walls by : David B. Woodham
Download or read book Construction and Monitoring of Post-tensioned Masonry Sound Walls written by David B. Woodham and published by . This book was released on 2002 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to document the installation of a post-tensioned concrete masonry sound wall constructed as part of a widening and sound wall project along US 36 near Denver, Colorado. In addition, the wall was instrumented at the time of construction to monitor the loss in prestress in the steel tendons over time due to concrete masonry creep and shrinkage and steel relaxation. Tendon tension was monitored for one year to obtain values for the accumulated losses. Accurate losses in post-tensioned concrete masonry are important for economical design. Currently, there are limited data to support an accurate prediction of prestress loss in concrete masonry.

Book Synopsis Sampling Location Impact on Measured Asphalt Content of Hot Mix Asphalt by : Mohammad Abu-Hassan
Download or read book Sampling Location Impact on Measured Asphalt Content of Hot Mix Asphalt written by Mohammad Abu-Hassan and published by . This book was released on 2002 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 2000, the Colorado Department of Transportation (CDOT) requested a forensic study of a project located on I-24 north of Denver. The request was made because, within a year of the 1997 overlay, longitudinal cracking appeared in the surface. Transverse cracks were attributed to reflective cracking. However, the longitudinal cracks appeared to be surface initiated. In October 2000, a forensic team reviewed the project and established a sampling and testing plan to take cores from the roadway. Based on data analysis of the cores, the higher than expected in-place air voids, the low effective asphalt, and segregation within the mat, all contributed to the early cracking.
