Title
Repair of concrete damaged by reinforcement corrosion, 1984
Publisher
Concrete Society
Camberley, UK
Abstract
The principle factors which cause deterioration of reinforcement are described. Detailed guidance on diagnosis of the cause of corrosion and on inspection and testing is given. The general principles of concrete repair, the stages in the repair process, operation factors and choice of methods are discussed. Guidance is given on the main systems currently used: recasting, sprayed concrete and mortar, hand-applied plain and polymer-modified cementitious mortars; repair of cracks; coatings. Aspects of the conditions of contract, specification and measurement are discussed.

Review
"...this is an important new book that will become a standard for introductory seismology courses taught by many universities. I am already using it this semester and am getting positive feedback from my students. I also would recommend it to a range of geophysicists who wanted to educate themselves further on the fundamentals of seismology."
--Gary L. Pavlis, Department of Geological Sciences, Indiana University
Product Description
Intended as an introduction to the field, Modern Global Seismology is a complete, self-contained primer on seismology. It features extensive coverage of all related aspects, from observational data through prediction, emphasizing the fundamental theories and physics governing seismic waves--both natural and anthropogenic. Based on thoroughly class-tested material, the text provides a unique perspective on the earths large-scale internal structure and dynamic processes, particularly earthquake sources, and on the application of theory to the dynamic processes of the earths upper skin.
Authored by two experts in the field of geophysics. this insightful text is designed for the first-year graduate course in seismology. Exploration seismologists will also find it an invaluable resource on topics such as elastic-wave propagation, seismicinstrumentation, and seismogram analysis useful in interpreting their high-resolution images of structure for oil and mineral resource exploration.
Key Features
* More than 400 illustrations, many from recent research articles, help readers visualize mathematical relationships

INTRODUCTION
In the winter of 1988, NYSDOT resident maintenance engineers were asked to send the Geotechnical Engineering Bureau lists of rock slope locations in their areas of responsibility that might conceivably be considered potential rockfall problem sites, screening them by the following criteria (listed it, order of importance.) :
1 . Areas with rockfall histories,
2. Posted rockfall zones,
3 . Obviously unstable rock masses,
4. Overhanging rocks,
5. Highly fractured and jointed oversteepened slopes (those higher than the setback from
the shoulder edge),
6. Areas of ice buildup on slopes,
7. Fallen rock in ditches,
8. New cracks or gaps in the rock,
9. Areas with soil deltas at the toes of rock slopes, and
10. Rock- slabs on slopes inclined toward the roadway.
A total of 1741 sites were identified and then evaluated by geologists from the Geotechnical Engineering Bureau, using an initial rating system based on a procedure originally developed for the Federal Highway Administration (FHAN'A) by Duncan C. Wyllie of the. geotechnical consulting firm of Golder Associates. This procedure was considered state-of-the art at the time, and was included in FHWA's Rock Slopes manual . Although the Department used this system in developing a rock slope ranking, no implementation policy was established. Also, identification of potential rockfall sites is an open-ended process, because sites may be added at any time. NZ'SDOT has now devised a revised system believed to have these three distinct advantages:
It isolates three components of a possible rockfall-vehicle accident as independent factors,
It more objectively addresses the cluestion of how much risk is associated with a falling rock flitting a vehicle, as well as the risk of a vehicle hitting a fallen rock, and
It considers not only risk posed by an existing rock slope, but level of risk remaining after reinediation .
The proposed rating procedure for rock slopes was presented to the Assistant Commissioner and Chief Engineer, approved, and a working draft issued in May 1993.

MECHANICALLY STABILIZED EARTH SYSTEM INSPECTION MANUAL
Publisher: NEW YORK STATE DEPARTMENT OF TRANSPORTATION
Pages: 95
Date: April 2007
PREFACE
The purpose of this manual is to provide New Yorh State Department of Transportation Construction Inspectors with a quick and easy-to-use set of inspection guidelines for the installation of Mechanically Stabilized Earth Systems (MSES) that utilize inextensible metallic reinforcements i. e., reinforcing strips, bar mats or wire mesh. The enclosed check lists are intended to serve as reminders to inspectors of unportant aspects for the successfid construction of MSES.
Prior to using this manual, inspectors should become familiar with the general concepts of MSES. Thus information can be found in Chapters 1, 2 & 3 of the Federal Highway Administration Publication No. FHVVA-N-HI-00-043, titled "Mechanically Stabilized Earth Walls and Reinforced Soil Slopes Design and Construction Guidelines", wl-tich is included as Appendix 1 of tills manual. In addition, it is imperative that Engineers-In-Charge obtain from the Contractor and review copies of the MSES designers/suppliers Construction Manual. The MSES Designerf`Supplier's Construction Manual contains detailed fi ornlation for the construction of a particular MSES and provides the necessary guidance during the construction inspection process .

PDF 506 pages 10.49 MB
Hydroinformatics is an emerging subject that is expected to gather speed, momentum and critical mass throughout the forthcoming decades of the 21st century. This book provides a broad account of numerous advances in that field - a rapidly developing discipline covering the application of information and communication technologies, modelling and computational intelligence in aquatic environments. A systematic survey, classified according to the methods used (neural networks, fuzzy logic and evolutionary optimization, in particular) is offered, together with illustrated practical applications for solving various water-related issues. ...
