This book was released on 1990 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Wabocrete FMV bridge deck expansion joint system was installed on the Alternate Rte. 58 bridge over the Clinch River in November 1986. The bridge was placed in service in mid-1987. The report concerns an installation and performance evaluation of the joint system. It was found that the Wabocrete FMV joint system offers some installation advantages over preformed joint systems. The blockout area of the bridge deck does not have to be as smooth or as precisely dimensioned since the joint's anchorage system can be leveled prior to placement of the bonding material. Installation and future maintenance problems involving anchor bolts are eliminated since the system relies on bond rather than mechanical anchorages. After over two years of service, the Vabocrete system has performed well. During this period, the joint has accommodated all thermal and structural movements, withstood traffic impacts and remained leak proof. The joint does tend to accumulate debris and should be routinely cleaned. The performance of the joint during the period of the study has not given any reason to suggest that it not be used on new bridge decks similar to the one studied. A longer term evaluation, however, would be necessary for a fullrecommendation. The use of the Wabocrete FMV, and similar systems, as retrofit on older bridges should be approached with caution. Furthermore, these systems shouldprobably not be used in retrofit situations in conjunction with adjacent asphaltic overlays.

This book was released on 1984 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The findings from this study were based on limited data. Requests for candidate structures for the inspections indicated that relatively few suitable bridges were available. Only 6 of those bridges could be skid tested. A further limitation was that, since the texturing specification was relatively new, the effect of traffic wear over a substantial period of time could not be measured. Skid resistance data from tests with treaded tires at 40 mph in the traffic lanes of interstate highway bridges, obtained routinely as part of another program, were available to indicate the effect of wear on earlier bridge deck textures.

Available in PDF, EPUB and Kindle. Book excerpt: The design and fabrication of bridge expansion joint (or movement) systems comprise a rapidly evolving industry. New designs are constantly being presented for trial, often on a piecemeal basis. Occasionally, failures of products occur without sufficient documentation, resulting in inadequate dissemination of the details of the installations to other potential users. It was believed that a systematic evaluation process involving users of joint sealing systems and the Virginia Department of Transportation's (VDOT) New Products Committee was required to ensure that up to date information on available products, their prescribed uses, installation procedures, and performance would be available across VDOT. The research procedure employed in this evaluation was a series of case studies of individual trials of joint sealing systems. Care was taken to ensure the involvement of all interested parties within VDOT and to include the joint manufacturer (vendor) in any experimental installation. The subject study was a limited evaluation of those joint sealing systems used by VDOT during the past several years. It did not include the full array of products available to the bridge engineering community, and it was not necessarily based on numerous installations of every joint system. Since the study concentrated on joint sealing systems, open expansion joint systems, including butt, sliding plate, and finger joints, were not evaluated. Larger modular joint systems were also excluded. The results of this study were mixed with regard to the performance of the generic systems evaluated. Each system has served successfully, and evaluations have shown failed installations of each. None can be assumed to last indefinitely. Adherence to recommended installation procedures is essential to attaining satisfactory service from a joint sealing system. The vendor should be required to have competent representation present during the entire time of the initial installation of any product. The individual in charge of the installation must be completely familiar with the details and the underlying logic of the operation. Bonding of the elastomeric component of the sealing system (which accommodates joint movement) to the faces of the joint is a critical factor in the performance of most systems. Due care should be taken in cleaning the joint faces, ensuring that the surfaces are dry, and properly applying any adhesive.

Available in PDF, EPUB and Kindle. Book excerpt: Asphaltic Plug Joint is an expansion joint that is used for new and rehabilitated bridges. It provides a smooth and watertight surface free of debris; and offers simple, easy and staged construction. Asphaltic plug joint can be repaired segmentally and it is cheaper than most other expansion joint types. The durability and performance of asphaltic plug joints depend greatly on the temperature variations. In high temperatures APJs are susceptible to rutting, heaving, and delamination. In low temperatures, asphaltic plug joint area may develop spalling, pot holes, debonding and exposure of metal plate. Recently, over 25% of NDOT District III bridges have experimented failure of their newly constructed asphaltic plug joints. This premature failure has been observed to be predominantly in bridges having high movement decks (over 2 inches). While designed for 5 to 8 years of service, those deck joints need significant maintenance within six months of service. In an attempt to address the problems encountered with the NDOT bridge deck asphaltic plug joints, this investigation intended to: (1) assess the condition and the extent of the problems associated with the asphaltic plug joints placed in the three NDOT districts; (2) compile available published and unpublished information, and to conduct a national survey to all departments of transportation; and (3) analyze the compiled relevant information and data, and to offer recommendations regarding quantifiable design parameters which can be used for proper construction of asphaltic plug joints. Properly selected materials, sound designs, viable construction methods, and maintenance strategies can lead to attaining improved bridge deck systems that can meet a set of performance criteria, as well as result in cost saving. The information presented in this report should assist NDOT in dealing with premature failure of asphaltic plug joints.
Download or read book Evaluation of Elastomeric Concrete in Bridge Expansion Joint Header Repair Applications written by Jennifer Distlehorst and published by . This book was released on 2005 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastomeric concretes were developed to prevent the spalling of the portland cement concrete adjacent to bridge deck expansion joints. Two types of elastomeric concretes were installed on I-135 bridges in Wichita in 1991. These joints and several others on I-135 with both elastomeric and conventional concrete header materials were surveyed annually for the next ten years. Spalling at each joint, rutting of the elastomeric materials and overall condition of the materials were measured and recorded. Laboratory tests of field-cast specimens were performed to determine the mechanical properties of the materials. The results of the tests and surveys show that the elastomeric concretes reduced spalling at bridge expansion joints. However, the joint headers formed of elastomeric concretes were as likely to develop distress as were the portland cement concrete joint headers.

Book excerpt: This report documents a study to evaluate promising bridge deck expansion joints with the intent of finding the most maintenance free and water-proof expansion devices for use in Colorado. The evaluation included inspections and measurements during construction and post construction. The ability of a device to remain water tight is the most important quality used to determine the success of the device. Proper installation during construction is one of the most important factors which will ultimately determine the success of an expansion joint. Neoprene compression joint seals are recommended for future joints whenever possible. On flex joints have also been shown to perform well, however, further evaluations are required before firm recommendations are made.
