Volume 1: Concepts, Methodology and Chemical Analysis. This 3-volume reference presents the latest findings in impact assessment of recycled hazardous waste materials on surface and ground waters. Topics covered include chemodynamics, toxicology, modeling and information systems. The book serves as a practical guide for the monitoring, design, management, or conduct of environmental impact assessment. Each volume contains the table of contents of all volumes.
This synthesis on the use of recycled rubber tires in highways will be of interest to administrators and policy-makers; pavement, materials, geotechnical, environmental, and traffic operations engineers; and research engineers involved with highway design and construction issues. Information is provided on the uses of rubber tires in asphalt paving materials as well as other uses, such as on fills and embankments, for erosion control and on railroad grade crossings. Specifically, information is included which identifies the agencies using or implementing applications for recycled rubber tires and defines the design parameters, technical and construction limitations, performance, costs, benefits, environmental limitations, specifications, and availability. This synthesis of information defines the use of recycled rubber tires in highways and is based on a review of nearly 500 references and on information recorded from state highway agency responses to a 1991 survey of practice. Updates are included for as much of the state practice information possible through 1993. The use of scrap tires for highway applications is dynamic with regard to policy and technical issues. Therefore, the reader should keep in mind that the information presented reflects the best available data at a particular time. The synthesis also identifies current research in the topic area, critical research needs, and legislative issues that affect application and use of recycled rubber tires.
The Virginia Department of Transportation (VDOT) is obligated by House Joint Resolution 453 passed in 1995 by Virginia's General Assembly to develop and implement a pollution prevention (P2) program. The primary purpose of this study was to develop a protocol whereby VDOT could quickly and economically evaluate the feasibility of implementing P2 opportunities identified as requiring additional study. In addition, three P2 opportunities, the use of aqueous parts washers, recycled plastic lumber, and lead acid battery extenders, were evaluated using the developed protocol. Evaluation criteria taken from various literature sources were used to develop the protocol. After using the protocol to evaluate the three P2 opportunities in question, the researcher concluded that the protocol will be a useful tool for VDOT to use when determining what opportunities to implement as part of its agency-wide Pollution Prevention Plan. With regard to the P2 opportunities evaluated, the researcher concluded that (1) aqueous parts washers were comparable or superior to solvent-based washers economically, technically, and environmentally; (2) recycled plastic lumber suffers from quality control problems, making it impractical to use for signposts; and (3) although lead acid battery extenders show great promise, little technical information is available to substantiate vendor claims.
This report presents a basic overview and assessment of different concepts and technologies of using polymer composites in structures generally used for highway safety. The structural systems included a highway barrier guardrail with its posts and blockouts, sign posts, concrete reinforcing rebars, breakaway couplers, and crushable plastic cushions to protect errant drivers from roadside sign and utility posts, and small trees. The composites included fiber reinforced plastics (FRP) in laminated and bar forms, and commercially available recycled and reconstituted structural plastic composites. Commercially available FRP composites, recycled plastic composites, and several conceptual designs and prototype components were assessed and tested. The results showed many potential advantages of using composites in almost all the structures considered, but one-to-one replacement of conventional materials was not always found attractive. For deriving maximum benefits from fiber composites, the basic performance of the given structures should be reassessed and then composites should be designed at the materials level using innovative fiber architecture and appropriate manufacturing technologies that can meet those performance requirements.
Preface 2012 edition: The United States Code is the official codification of the general and permanent laws of the United States. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First session, enacted between January 3, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 USC 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office. -- John. A. Boehner, Speaker of the House of Representatives, Washington, D.C., January 15, 2013--Page VII.
