• Abstract:
  The Louisiana Transportation Research Center has established a Pavement Research Facility (PRF). The core of the PRF is a testing machine that is capable of conducting full-scale simulated and accelerated load testing of pavement materials, construction, and performance; and to verify mathematical models of mechanistic pavement design procedures. ; Instrumentation and data acquisition plays an integral part in the PRF to provide a system for monitoring materials and systems responses due to traffic loads and environmental conditions. These responses are essential for pavement materials characterization and performance evaluation. ; The data acquisition system developed for the Louisiana ALD includes a 486 based Personal Computer, plug-in distributed Input/Output board, interface circuit boards, signal conditioning modules, and Graphical User Interface (GUI) software development tools. Menu driven user friendly software, Accelerated Loading Device Instrumentation Software (ALDIS), was developed in C language under Labwindows environment. ALDIS offers attractive GUI features to acquire data from most common types of sensors at various sampling rates, data storage and management in ASCII/Binary format and real-time graphical presentation of the data.
