This book was released on 2006 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the interest of providing tools for the cost-effective maintenance of an aging inventory of bridges, a method for comparing feasible repair/replacement sequences for low-slump concrete overlays for bridge decks is developed. The method relies on a technique for computing deterioration curves using inspection data from the National Bridge Inventory. Over twenty years of inspection data for bridge decks in Minnesota, which were overlaid with low-slump concrete overlays placed between 1974 and 1981, was used. The deterioration curves were assumed dependent on several material and geometric variables identified by means of a literature review, and the statistical significance of these parameters on deterioration rates was examined. These variables include span length, average daily traffic, and superstructure material type, and piecewise linear deterioration curves were constructed for various subgroups with similar deterioration characteristics. Present value cost analysis was used to price the available options by identifying the sequence of repairs that has the least cost while maintaining a specified performance measure. The present value analysis considers the costs and timing of repair/replacement sequences, inflation, and the discount rate.

Book Synopsis Concrete Solutions by : Michael Grantham
Download or read book Concrete Solutions written by Michael Grantham and published by CRC Press. This book was released on 2016-09-19 with total page 1364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete Solutions contains the contributions from some 30 countries to Concrete Solutions, the 6th International Conference on Concrete Repair (Thessaloniki, Greece, 20-23 June 2016). Strengthening and retrofitting are major themes in this volume, with NDT and electrochemical repair following closely, discussing the latest advances and technologies in concrete repair. The book brings together some interesting and challenging theoretical approaches and questions if we really understand and approach such topics as corrosion monitoring correctly. Concrete Solutions is an essential reference work for those working in the concrete repair field, from engineers to architects and from students to clients. The Concrete Solutions Series of international conferences on concrete repair began in 2003 with a conference held in St. Malo, France in association with INSA Rennes. Subsequent conferences have seen the Series partnering with the University of Padua (Italy) in 2009, with TU Dresden (Germany) in 2011 and with Queen’s University Belfast (Northern Ireland) in 2014. In 2016 Thessaloniki (Greece) hosted the conference, partnering with both Aristotle University of Thessaloniki (AUTH) and Democritus University of Thrace (DUTH). The next conference in the series will be held in 2019 in Istanbul.

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.
Book Synopsis Performance of Concrete Bridge Deck Overlays by : Chris Anderson
Download or read book Performance of Concrete Bridge Deck Overlays written by Chris Anderson and published by . This book was released on 1990 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chloride-ions penetrating into bridge decks and corroding the steel have been a major problem. As the steel corrodes it exerts stresses on the surrounding concrete. When the stresses exceed the strength of the concrete, cracks or delaminations occur. This, of course, causes deterioration and spalling of bridge deck surfaces. Both the Latex and Iowa Method were used to repair bridge decks for this project. The concrete was removed down to the steel and replaced with approximately 1 1/2 inches of low slump or latex modified concrete. The removal of unsound concrete below the top layer of steel was sometimes necessary. The objective of this project was to determine if the bridge overlays would provide a cost effective method of rehabilitation. To do this, unsound and delaminated concrete was removed and replaced by an overlay of low slump or latex modified concrete.

Book Synopsis Performance and Service Life of Low-slump-concrete Bridge Deck Overlays in New York by : William P. Chamberlin
Download or read book Performance and Service Life of Low-slump-concrete Bridge Deck Overlays in New York written by William P. Chamberlin and published by . This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty randomly selected concrete bridge decks in New York State, overlaid with low-slump concrete, were studied in 1985 after an average of 5 years of service. The investigation included recording surface defects, measuring delamination and half-cell potentials, and sampling and testing for deck chloride profile. Conclusions are drawn with regard to the nature and significance of the observed damage, and estimates are made of service life expectancy. Policy implications for the New York State Department of Transportation are discussed.

This book was released on 1986 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete bridge deck deterioration, especially premature deterioration, is a major problem for the state transportation agencies throughout the United States. Moreover, this deck deterioration, which manifests itself in the form of cracking, scaling and spalling, accounts for a large portion of the number of the nation's structurally deficient bridges. In particular, the New England states have expressed concern over the dilemma of repair versus replacement strategies for those decks on the grey zone (deck condition code 4-6). Thus, the purpose of this thesis is to provide a preliminary investigation into the systematic approach to the repair versus replacement decision-making process for deteriorated concrete decks. For a large number of states, the existing decision-making process is characterized by a piecemeal synthesis oriented towards emphasizing the advantages of one repair or replacement alternative and underestimating its disadvantages. An actual cost-effective comparison of all possible alternatives is not routinely undertaken.

Book Synopsis Bridge Deck Asphalt Concrete Pavement Armoring by : Matthew Haynes
Download or read book Bridge Deck Asphalt Concrete Pavement Armoring written by Matthew Haynes and published by . This book was released on 2020 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deterioration of the concrete bridge deck is one of the most significant problems affecting the service life of bridges in the United States. Moisture penetration into the asphalt overlay and standing water on the concrete bridge deck result in expansion and contraction at the interface on the bridge deck during freeze-thaw cycles. This causes debonding at the interface and results in an increased rate of deterioration for the asphalt concrete overlay. Additionally, the deicing salts permeate into the deck and cause corrosion of the steel reinforcement, weakening the structural integrity of the bridge. Waterproofing membranes with an asphalt overlay were developed as a strategy to protect concrete bridge decks. The main goals of this study were to provide the industry and Oregon Department of Transportation (ODOT) with better insight on the failure mechanisms of asphalt overlays on concrete bridge decks and establish field and laboratory experiments to evaluate the performance of these overlays. The most effective deck waterproofing systems and overlay strategies (in terms of both cost and performance) were determined for concrete bridge decks in Oregon. By determining the most effective waterproofing methods and strategies, this research will serve to decrease repair and replacement costs, and increase the service life of asphalt overlays on concrete bridge decks in Oregon.
