Available in PDF, EPUB and Kindle. Book excerpt: According to recent surveys conducted with state Department of Transportations (DOTs) and asphalt contractors, commonly used asphalt mixture properties are not directly reflecting the long-term performance of asphalt mixtures. In addition, there are several new additives, polymers, rubbers, and high-quality binder types incorporated into asphalt mixtures today. Volumetric mixture design methods are not capable of capturing the benefits of using all these new technologies on asphalt mixture performance. Furthermore, the interaction of virgin binders with reclaimed asphalt pavement (RAP) mixtures with high binder replacement contents and the level of RAP binder blending into the asphalt mixture are still not well understood. Due to all these complications related to the more complex structure of today's asphalt mixtures, simple volumetric evaluations to determine the optimum binder content may not result in reliable asphalt mixture designs. Two volumetrically identical mixtures may provide completely different rutting and cracking performance according to laboratory tests. For all these reasons, in this study, a procedure to incorporate performance tests for rutting and cracking (with a new long-term aging protocol developed in this study) into current asphalt mixture design methods was developed to be able to validate or revise the optimum binder content determined by the volumetric mix design method. Developed balanced mix design method is expected to improve the long-term performance of asphalt-surfaced pavements in Oregon.

This book was released on 2003 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global response to COVID-19 has demonstrated the importance of vigilance and preparedness for infectious diseases, particularly influenza. There is a need for more effective influenza vaccines and modern manufacturing technologies that are adaptable and scalable to meet demand during a pandemic. The rapid development of COVID-19 vaccines has demonstrated what is possible with extensive data sharing, researchers who have the necessary resources and novel technologies to conduct and apply their research, rolling review by regulators, and public-private partnerships. As demonstrated throughout the response to COVID-19, the process of research and development of novel vaccines can be significantly optimized when stakeholders are provided with the resources and technologies needed to support their response. Vaccine Research and Development to Advance Pandemic and Seasonal Influenza Preparedness and Response focuses on how to leverage the knowledge gained from the COVID-19 pandemic to optimize vaccine research and development (R&D) to support the prevention and control of seasonal and pandemic influenza. The committee's findings address four dimensions of vaccine R&D: (1) basic and translational science, (2) clinical science, (3) manufacturing science, and (4) regulatory science.

Download or read book Waterproofing Membranes for Concrete Bridge Decks written by David G. Manning and published by Transportation Research Board. This book was released on 1995 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to research, specifications, materials, design, and construction engineers; contract and specification administrators; agency project managers and staff; and concrete bridge deck construction contractors. This synthesis describes the state of the practice with respect to the development and present status of waterproofing membranes for concrete bridge decks. This report of the Transportation Research Board describes the use of waterproofing systems applied to new bridge decks and the rehabilitation of deteriorated concrete bridge decks. In addition, this synthesis describes current practice with regard to methods for assessing the effectiveness of membranes, criteria for use, installation practices, and factors that affect the performance of waterproofing systems in new construction and rehabilitation. Suggestions for future research are also included.

This book was released on 1994 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The final product of the Strategic Highway Research Program (SHRP) Asphalt Research Program is the SUPERPAVE (registered trademark) mix design system for new construction and overlays. This system employs a series of new performance-based specifications, test methods, and practices for material selection, accelerated performance testing, and mix design. This report documents these new specifications and procedures in a format suitable for eventual American Association of State Highway and Transportation Officials (AASHTO) standardization.
Download or read book Handbook of Test Development written by Suzanne Lane and published by Routledge. This book was released on 2015-10-08 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of the Handbook of Test Development provides graduate students and professionals with an up-to-date, research-oriented guide to the latest developments in the field. Including thirty-two chapters by well-known scholars and practitioners, it is divided into five sections, covering the foundations of test development, content definition, item development, test design and form assembly, and the processes of test administration, documentation, and evaluation. Keenly aware of developments in the field since the publication of the first edition, including changes in technology, the evolution of psychometric theory, and the increased demands for effective tests via educational policy, the editors of this edition include new chapters on assessing noncognitive skills, measuring growth and learning progressions, automated item generation and test assembly, and computerized scoring of constructed responses. The volume also includes expanded coverage of performance testing, validity, fairness, and numerous other topics. Edited by Suzanne Lane, Mark R. Raymond, and Thomas M. Haladyna, The Handbook of Test Development, 2nd edition, is based on the revised Standards for Educational and Psychological Testing, and is appropriate for graduate courses and seminars that deal with test development and usage, professional testing services and credentialing agencies, state and local boards of education, and academic libraries serving these groups.

This book was released on 2011 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 684: Enhancing Internal Trip Capture Estimation for Mixed-Use Developments explores an improved methodology to estimate how many internal trips will be generated in mixed-use developments - trips for which both the origin and destination are within the development. The methodology estimates morning and afternoon peak-period trips to and from six specific land use categories: office, retail, restaurant, residential, cinema, and hotel. The research team analyzed existing data from prior surveys and collected new data at three mixed-use development sites. The resulting methodology is incorporated into a spreadsheet model, which is available online for download.
