This is the first report of 6 tasks to be performed in an effort to establish locally-based quality and performance criteria for asphalts, and ultimately to develop performance-related specifications based on simple physicochemical methods. Three of the most promising chemical methods (high performance liquid chromatography (HPLC), thermal analysis, and X-ray diffraction were selected to analyze 4 different types of samples. The results will indicate the fundamental asphalt property variables that directly affect the field performance in Iowa. The details of the materials and procedures employed are described, and the results of the tests are presented.

Recent research on asphalt binder aging and rejuvenatorsKey data on asphalt performance and formulationsUpdates on tests and specificationsFully-searchable text on CD-ROM (included) This series volume comprises research papers and technical reports developed within the U.S.-based Association of Asphalt Paving Technologists. The book is divided into sessions focused on technology, specifications, cold recycling of RAP, and rejuvenators, with special emphasis on aging and on how rejuvenators are modeled, formulated and used to improve asphalt binders and prevent cracking. The CD-ROM displays figures and illustrations in articles in full color along with a title screen and main menu screen. Each user can link to all papers from the Table of Contents and Author Index and also link to papers and front matter by using the global bookmarks which allow navigation of the entire CD-ROM from every article. Search features on the CD-ROM can be by full text including all key words, article title, author name, and session title. The CD-ROM has Autorun feature for Windows 2000 with Service Pack 4 or higher products along with the program for Adobe Acrobat Reader with Search 11.0. One year of technical support is included with your purchase of this product.
This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, presents evaluations of the capability of portable spectroscopy devices to “fingerprint” typical construction materials. The spectroscopy devices are evaluated in laboratory conditions as well as in the field to verify material-testing method combinations found successful. The report also documents simple, easy-to-use nondestructive testing procedures for use in the field to ensure quality construction.
Fifteen papers from the symposium held in Philadelphia, March 1990, examine the uses of thermomechanical analysis and thermodilatometry in materials science, addressing instrumentation, techniques, and applications. Annotation copyright Book News, Inc. Portland, Or.
