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.

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.

Book excerpt: This manual provides instructions to personnel of the Texas State Department of Highways and Public Transportation for collecting, developing, and processing data for the "THD Flexible Pavement Design System." Included in the manual are coding instructions for one main program and two subsidiary programs. The pavement design system provides for generation of several initial design strategies for new pavement construction as well as several overlay strategies for existing pavements. These strategies are listed in order of increasing total cost. Stiffness Coefficients are used to characterize the materials to be used in new pavement construction, and the Surface Curvature Index is used to characterize existing pavement structures. Uncertainty in the predicted pavement life is treated so that the designer may select various confidence levels.

This book was released on 2009-11-23 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “soft computing” applies to variants of and combinations under the four broad categories of evolutionary computing, neural networks, fuzzy logic, and Bayesian statistics. Although each one has its separate strengths, the complem- tary nature of these techniques when used in combination (hybrid) makes them a powerful alternative for solving complex problems where conventional mat- matical methods fail. The use of intelligent and soft computing techniques in the field of geo- chanical and pavement engineering has steadily increased over the past decade owing to their ability to admit approximate reasoning, imprecision, uncertainty and partial truth. Since real-life infrastructure engineering decisions are made in ambiguous environments that require human expertise, the application of soft computing techniques has been an attractive option in pavement and geomecha- cal modeling. The objective of this carefully edited book is to highlight key recent advances made in the application of soft computing techniques in pavement and geo- chanical systems. Soft computing techniques discussed in this book include, but are not limited to: neural networks, evolutionary computing, swarm intelligence, probabilistic modeling, kernel machines, knowledge discovery and data mining, neuro-fuzzy systems and hybrid approaches. Highlighted application areas include infrastructure materials modeling, pavement analysis and design, rapid interpre- tion of nondestructive testing results, porous asphalt concrete distress modeling, model parameter identification, pavement engineering inversion problems, s- grade soils characterization, and backcalculation of pavement layer thickness and moduli.
