Book Description
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 Description
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 Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 338: Thin and Ultra-Thin Whitetopping summarizes available information to document how state departments of transportation and others are currently using thin and ultra-thin whitetopping overlays among various pavement rehabilitation alternatives. The report covers all stages of the proper application of whitetopping overlays, including project selection, design, materials selection, construction, maintenance, and eventual rehabilitation or replacement.

Book Description
Does the identification number 60 indicate a toxic substance or a flammable solid, in the molten state at an elevated temperature? Does the identification number 1035 indicate ethane or butane? What is the difference between natural gas transmission pipelines and natural gas distribution pipelines? If you came upon an overturned truck on the highway that was leaking, would you be able to identify if it was hazardous and know what steps to take? Questions like these and more are answered in the Emergency Response Guidebook. Learn how to identify symbols for and vehicles carrying toxic, flammable, explosive, radioactive, or otherwise harmful substances and how to respond once an incident involving those substances has been identified. Always be prepared in situations that are unfamiliar and dangerous and know how to rectify them. Keeping this guide around at all times will ensure that, if you were to come upon a transportation situation involving hazardous substances or dangerous goods, you will be able to help keep others and yourself out of danger. With color-coded pages for quick and easy reference, this is the official manual used by first responders in the United States and Canada for transportation incidents involving dangerous goods or hazardous materials.
