Abstract

The Louisiana Transportation Research Center has purchased an accelerated loading device that is capable of conducting full-scale simulated and accelerated load testing of pavements. A sophisticated data acquisition system was developed for monitoring various types of sensors installed in pavements that help in understanding pavement materials responses associated with simulated traffic loading and environmental factors. In addition, this system is capable of performing such tasks as data management, data reduction, and graphical presentation. Performance validation tests were conducted on an instrumented pavement site to evaluate the developed system. Two types of sensors (H-gauge, T-type thermocouple) and three types of loading systems (passenger vehicle, falling weight deflectometer, and Dynaflect) were used in this study.
