Download or read book Material Property and Quality Control Specifications for Elastomeric Concrete Used at Bridge Deck Joints written by Janos Gergely and published by . This book was released on 2009 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to determine the minimum requirements in order to ensure satisfactory long-term performance and to develop a quality control program, including field sampling and testing during installation. There were two main phases to the research performed within this study. The first phase dealt with identification of critical material properties to establish a prequalification program. A total of eleven products were obtained and lab-mixed to determine the effects of varying polymer and aggregate types. This phase would also provide a baseline for material property values throughout the remainder of the research. In the second phase, site visits were made to fresh installations throughout North Carolina to obtain sample elastomeric concrete mixed in the field. Those sites were later 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: An international team of experts has joined forces to produce the Bridge Engineering Handbook. They address all facets-the planning, design, inspection, construction, and maintenance of a variety of bridge structures-creating a must-have resource for every bridge engineer. This unique, comprehensive reference provides the means to review standard practices and keep abreast of new developments and state-of-the-art practices. Comprising 67 chapters in seven sections, the authors present: Fundamentals: Provides the basic concepts and theory of bridge engineering Superstructure Design: Discusses all types of bridges Substructure Design: Addresses columns, piers, abutments, and foundations Seismic Design: Presents the latest in seismic bridge design Construction and Maintenance: Focuses on the practical issues of bridge structures Special Topics: Offers new and important information and unique solutions Worldwide Practice: Summarizes bridge engineering practices around the world. Discover virtually all you need to know about any type of bridge: Reinforced, Segmental, and Prestressed Concrete Steel beam and plate girder Steel box girder Orthotropic deck Horizontally curved Truss Arch Suspension Cable-stayed Timber Movable Floating Railroad Special attention is given to rehabilitation, retrofit, and maintenance, and the Bridge Engineering Handbook offers over 1,600 tables, charts, and illustrations in ready-to-use format. An abundance of worked-out examples give readers step-by-step design procedures and the section on Worldwide Practice provides a broad and valuable perspective on the "big picture" of bridge engineering.
