Download or read book Flexible Pavement Design System FPS 19W written by Wenting Liu and published by . This book was released on 2001 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: FPS 19W is the approved flexible pavement thickness design system used by the Texas Department of Transportation (TxDOT). Project 0-1869 made several enhancements to this system, including: a) transferring the system to the Windows® platform, b) automating the Texas Triaxial system to provide a thickness checking system, c) incorporating stress and strain computational subsystem so that classical fatigue and rutting lives can be estimated for the designed pavement, and d) incorporating an extensive on-line help system. In this project the models within FPS 19W were further calibrated. New approaches were also incorporated for handling designs on pavements with very thick flexible bases.
Download or read book Flexible Pavement Design System FPS 19 written by Thomas Scullion and published by . This book was released on 1998 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: FPS 19 is the latest version of the flexible pavement design system developed by the Texas Transportation Institute for TxDOT. This version uses backcalculated elastic moduli of the pavement layer materials in the pavement design process. The MODULUS 5.1 backcalculation procedure generates the input layer moduli. The WESLEA linear elastic computer program, embedded within FPS 19, computes pavement responses. The design equation used is the same as used in FPS 11 and documented in TTI Report 32-11. The main design parameter is the Surface Curvature Index computed at the midpoint of a set of dual tires loaded to 40 Kn (9,000 lbs). FPS 19 is microcomputer-based and compatible with MS-DOS Windows 95 and Windows NT when running under the DOS window. TxDOT is implementing the FPS 19 computer program statewide as part of its new flexible pavement design system.

This book was released on 1992 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to engineering managers, design engineers, traffic engineers, computer personnel, and others interested in advanced computer applications for highway design and operations. Information is provided on the history of knowledge based expert systems (KBES), current applications of these systems in transportation departments, potential applications, and hardware and software requirements. Additionally, some detailed programming information from two operational expert systems is included. There is growing use of computers in transportation departments, and KBES represent an area in which several highway agencies are gaining experience and obtaining promising results. This report of the Transportation Research Board describes the current state of the practice with respect to KBES, as well as the historical development of expert systems and the more general field of artificial intelligence. Experience with expert systems in transportation in summarized, including discussions of expert systems in operation and in development, based on a review of the literature and a survey of the states and experts in this field.

Download or read book Synthesis of Pavement Issues Related to High speed Corridors written by Joe W. Button and published by . This book was released on 2004 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project was to produce a synthesis of available information to support specific areas related to pavements for the safe, economical development of the Trans Texas Corridor (TTC). This synthesis is divided into nine sections, each of which deals with a specific topic or topics. These specific areas include (1) pavement design for heavy vehicles, (2) pavement design for light vehicles, (3) skid resistance issues on high-speed corridors, (4) issues related to traffic characterization, (5) smart pavements for high-speed corridors, (6) pavement material response to dynamic loads and performance prediction, (7) safety issues related to splash and spray, and (8) ride quality for high-speed corridors. Regarding these stated issues, this synthesis recommends state-of-the-art technology to the Texas Department of Transportation (TxDOT) for use during development of the TTC. It provides recommendations for future research to fill gaps in knowledge and to take emerging technology to the stage where it can be implemented during the design and construction of the TTC pavements. This is the first synthesis study to address issues related to the TTC. A secondary objective of this project was to determine if additional synthesis studies in other areas of transportation related to the TTC should be conducted and, if so, how the process might be improved. This synthesis recommends that future syntheses should be more focused on specific, maybe critical, issue(s); the researcher should be instructed to present only those findings that are really new, innovative, and potentially implementable. One element of the study should pursue non-transportation related technology that might be adapted to transportation issues.
