TRB's National Cooperative Highway Research Program (NCHRP) Report 670: Recommended Procedures for Testing and Evaluating Detectable Warning Systems explores a set of recommended test methods for evaluating the durability of detectable warning systems. These methods address exposure regimes, test procedures, and evaluation criteria to help select detectable warning systems that provide long-term performance and durability while meeting the requirements of the Americans with Disabilities Act Accessibility Guidelines. The appendix contained in the research agency's final report provides further elaboration on the work performed in this project. This appendix titled Research Leading to the Development of Methodology for Durability Assessment of Detectable Warning Systems is available online.

This book provides an understanding of peer-reviewed international construction materials and their testing methods in a simplified manner at a high technical level. It focuses on specific construction materials, such as cement, concrete, bricks, lime, paints, steel and so forth, distributed in ten different chapters. Using real-time quality control as the underlying determinant, the book material exclusively follows Indian, American, European, German and South African standards. Relevant modern sophisticated material testing techniques, like scanning electron microscope (SEM), thermo gravimetric analysis (TGA) and X-Ray diffraction (XRD), are also described. Aimed at undergraduate, senior undergraduate and early career professionals in civil engineering and construction engineering, this book Gives a clear background of material testing and its importance Includes step-by-step procedures for easy understanding of and for performing the tests Covers Indian, ASTM, South African, DIN German and European Standards Includes basic and advanced techniques for chemical admixtures Each chapter concludes with practice questions, including 400+ solved questions and 50+ test procedures in total
