This study shows the variation in pavement performance through instrumented pavement section under different climactic conditions. A section on Interstate 40 (I-40), near Albuquerque, New Mexico, USA, has been instrumented with 32 sensors including strain gauges, pressure plates, moisture probes, temperature probes, axle sensing strips, weather station and Weigh-in-Motion (WIM).
Analysis of Falling Weight Deflectometer Tests at Denver May 01, 2002 · Analysis of Falling Weight Deflectometer Tests at Denver International Airport Computer Applications to Airport Pavements Data collected from heavy weight deflectometers (HWD) tests at the Federal Aviation Administration (FAA) instrumented Portland cement concrete (PCC) pavement test site at Denver International Airport (DIA) are used to analyze the deflection response of the pavement.

Frost-Protected Shallow Foundation Design - Green Building Frost-protected shallow foundation design (FPSF) provides cold weather durability without excavation below the frost line. Recently designated a U.S. Department of Housing and Urban Developments (HUDs) Partnership for Advancing Technology in Housing (PATH) Top Ten Technology for 2004, the FPSF design concept has gained acceptance due to its insulation benefits, energy efficiency, and
the layout for construction. 1.3Background Design methods for concrete parking lot pavements are somewhat empirical and are based on the methods developed for the design of highway pavements (that is, the Portland Ce-ment Association method [Thickness 1984] and the AASH TO design method [AASHTO 1993]). These methods are prima-

IMPACT:Which Test to Use? Which Instrument to Buy Oct 01, 2001 · Instrumented impact can be performed either on a falling-weight tester, such as those supplied by Instron and Ceast, or on a pendulum-type instrument like those offered by Tinius Olsen and Atlas. Most instrumented drop-weight testers allow users to also perform the Izod and Charpy tests by changing the impact striker and fixture on the instrument.
