The asphaltic plug joints (APJs) are a type of bridge expansion joint that have been promoted as simple general purpose expansion devices for bridges with less than 50 mm (2 in.) total motion. APJs have been developed by trial and error and used when little engineering research existed outlining their complex behavior. To help designers to better understand this behavior and be able to properly apply them, the University of Wyoming has developed engineering-based design guidelines and material specifications. With the material relaxing by viscous flow at about the same rate as the bridge places motion demands on the joint, minimal loads and stresses are created. With these small loads almost no limit on the allowable motion exists from a structural perspective.

Asphalt is a complex but popular civil engineering material. Design engineers must understand these complexities in order to optimize its use. Whether or not it is used to pave a busy highway, waterproof a rooftop or smooth out an airport runway, Asphalt Materials Science and Technology acquaints engineers with the issues and technologies surrounding the proper selection and uses of asphalts. With this book in hand, researchers and engineering will find a valuable guide to the production, use and environmental aspect of asphalt. Covers the Nomenclature and Terminology for Asphalt including: Performance Graded (PG) Binders, Asphalt Cement (AC), Asphalt-Rubber (A-R) Binder, Asphalt Emulsion and Cutback Asphalt Includes Material Selection Considerations, Testing, and applications Biodegradation of Asphalt and environmental aspects of asphalt use
