Manus and published by . This book was released on 2008 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastomeric concrete has recently emerged as a new material in bridge expansion joint construction. However, the North Carolina Department of Transportation (NCDOT) does not currently have a quality control/assurance program addressing elastomeric concrete. The purpose of this report is to analyze elastomeric concrete so as to determine a quality control program for the NCDOT. In this study, site visits were made to fresh installations throughout North Carolina to obtain sample elastomeric concrete mixed in the field. Those same sites were revisited to obtain material from the same expansion joint after at least 4 months in-service. When revisited, samples were obtained through means of coring. Cored sample test data could then be compared to the fresh sampling data to determine changes in physical properties with time. Older existing joints (over 5 years in-service life) were also identified and sampled to determine the physical property changes associated with long-term cyclic loading and environmental weathering. To further understand the changes in physical properties due to weathering, a durability testing program was implemented. A total of 432 specimens were subjected to freeze-thaw, moisture-induced damage, and oil swell conditioning in this phase. The research performed within this study presents a foundation for establishing a comprehensive quality control/assurance program for elastomeric concrete used in the state of North Carolina.

This book was released on 1999-04-13 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expansion joints in bridges have long experienced the problem of inconsistent performance as well an unacceptably high incidence of premature failure; a situation caused by number of factors, including selection procedure and installation conditions. This report is the result of a study by a Working Group set up by the County Surveyors' Society and TRL Working Party on Highway Research whose objective was to propose the means to improve the consistency of performance and value for money of expansion joints, reducing the incidence of premature failure and leakage. Each aspect of joint selection, performance and maintenance was studied and a whole life cost study was carried out to weigh the benefits of high initial cost/long-life joints against low purchase cost/short-life options. This report presents the findings of the Working Group, including the most common reasons for joint failure, the shortcoming of the methods used to select joints and the total cost of an expansion joint.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expansion joints are important components of bridges that accommodate the movements between deck spans that result from thermal loads, traffic loads, and other environmental factors. Experience shows that joints undergo premature deterioration on a regular basis, thus leading to unexpected problems caused by leakage of water and other corrosive chemicals over the components of the superstructure and substructure, thus leading to premature deterioration of those components. Millions of dollars have been spent by the Virginia Department of Transportation (VDOT) over more than 50 years for repairs and replacements of joints. Several types of closed joints have been developed and installed in the past three decades to combat this problem. In addition, jointless details at piers and abutments have been developed and installed in the same time period to eliminate the need for joints. However, the issue persists. VDOT's Structure and Bridge Division has developed a new design for a flexible joint system with bonded and debonded zones. An elastomeric concrete material acts as the load-bearing surface and the component that allows free expansion and contraction. This joint system has been installed in selected pilot bridges on secondary roads for observation. This study evaluated the performance of this joint system and detailed the challenges faced in developing it. The elastomeric concrete plug joint system was successfully implemented in five pilot bridges in Virginia. Short-term performance of the system was satisfactory under Virginia weather conditions. Rutting during the summer months has not been observed even though one of the elastomeric materials had failed in the laboratory testing. Expansion cracking during the winter months was not observed in the first year after installation. It was determined that shore durometer hardness values can be used as a preliminary filter to select elastomeric material with resistance to permanent indentation. Dynamic modulus testing can be used as a measure of the toughness and flexibility of elastomeric concrete material under different temperatures. However, these tests do not give a complete picture of the material properties, so engineering judgment is also necessary in order to make decisions regarding the elastomeric materials. The Virginia Transportation Research Council and VDOT's Structure and Bridge Division should continue to monitor visually the performance of the elastomeric concrete plug joint systems installed during this study and continue to evaluate new elastomeric concrete candidates for the joint system. Further, the Virginia Transportation Research Council and VDOT's Structure and Bridge Division should expand the trials to other VDOT districts for various exposure conditions.
