Book Description
A systematic methodology is presented for highway agencies to use at the project level to determine the most cost-effective treatment, and its timing, for specific concrete bridge components that are deteriorating or are subject to deterioration. The methodology is set forth in the form of both a handbook and a computer program. The methodology in its present form applies only when the predominant concrete deterioration is associated with chloride-induced corrosion of the reinforcing steel. The methodology is designed to be flexible and can be tailored to suit the needs of individual highway agencies.

Book Description
The service life of Virginia's concrete bridge decks is generally controlled by chloride-induced corrosion of the reinforcing steel as a result of the application of winter maintenance deicing salts. A chloride corrosion model accounting for the variable input parameters using Monte Carlo resampling was developed. The model was validated using condition surveys from 10 Virginia bridge decks built with bare steel. The influence of changes in the construction specifications of w/c = 0.47 and 0.45 and w/cm = 0.45 and a cover depth increase from 2 to 2.75 inches was determined. Decks built under the specification of w/cm = 0.45 (using slag or fly ash) and a 2.75 inch cover depth have a maintenance free service life of greater than 100 years, regardless of the type of reinforcing steel. Galvanized, MMFX-2, and stainless steel, in order of increasing reliability of a service life of greater than 100 years, will provide a redundant corrosion protection system. Life cycle cost analyses were conducted for polymer concrete and portland cement based overlays as maintenance activities. The most economical alternative is dependent on individual structure conditions. The study developed a model and computer software that can be used to determine the time to first repair and rehabilitation of individual bridge decks taking into account the time for corrosion initiation, time from initiation to cracking, and time for corrosion damage to propagate to a state requiring repair.

Book Description
This volume contains the papers presented at IALCCE2018, the Sixth International Symposium on Life-Cycle Civil Engineering (IALCCE2018), held in Ghent, Belgium, October 28-31, 2018. It consists of a book of extended abstracts and a USB device with full papers including the Fazlur R. Khan lecture, 8 keynote lectures, and 390 technical papers from all over the world. Contributions relate to design, inspection, assessment, maintenance or optimization in the framework of life-cycle analysis of civil engineering structures and infrastructure systems. Life-cycle aspects that are developed and discussed range from structural safety and durability to sustainability, serviceability, robustness and resilience. Applications relate to buildings, bridges and viaducts, highways and runways, tunnels and underground structures, off-shore and marine structures, dams and hydraulic structures, prefabricated design, infrastructure systems, etc. During the IALCCE2018 conference a particular focus is put on the cross-fertilization between different sub-areas of expertise and the development of an overall vision for life-cycle analysis in civil engineering. The aim of the editors is to provide a valuable source of cutting edge information for anyone interested in life-cycle analysis and assessment in civil engineering, including researchers, practising engineers, consultants, contractors, decision makers and representatives from local authorities.

Book Description
This manual is a practical guide for state highway agency personnel who are faced with the day-to-day task of cost-effectively protecting repairing, and rehabilitating concrete bridges exposed to chloride laden environments. The manual addresses the chloride induced corrosion of reinforcing steel. Methods are presented to estimate the service life and remaining service life of concrete bridge components. Economic models are presented to enable selection of the most cost effective methods. These methods include standard physical, chemical, and experimental protection, repair, and rehabilitation. Also, rapid bridge deck protection, repair, and rehabilitation methods are presented. Two mechanized concrete removal methods, milling and hydrodemolition, are compared to the traditional method, pneumatic breakers. The advantages of combining the strengths of the three removal methods are also presented.

Book Description
This report is the result of the work of the former FIP Commission 10: Management and strengthening of concrete structures, which replaced to the former FIP Commission 10: Maintenance, operation and use in 1995. The former CEB Commission V: Operation and Use and in particular its Task Group 5.4: Assessment, maintenance and repair also played a role in this report. When in 1998 the FIP merged with the CEB to form the fib, the well advanced writing was completed by a small editorial group. The purpose of the report is twofold: to give an overview of the issues relating to the management of concrete structures in general and to add details about assessment and remedial action, as these are important technical aspects of management and maintenance systems. The more general aspects of asset management are dealt with in Chapter 1, aimed at owners and decision-makers. Chapters 2 and 3, aimed at consultants and contractors, deal with decision-making in the assessment process. A review of remediation techniques is given in Chapter 3, intended to help in the selection of remedial actions rather than in their execution. The report also includes some significant appendices regarding load testing, monitoring and fire, and also special considerations related to seismic retrofitting. Appendix 1 offers keywords that the various actors in this field could use for a common language.
