Instrumentation Experience at the Kansas Accelerated Pavement Testing Facility
Pavement test section instrumentation changes from laboratory to laboratory and also with the purposes and objectives of each test. There is a need for sharing knowledge of successes and failure sin instrumentation of pavement sections. This paper describes the instrumentation from a geocellular system-reinforced pavement experiment at the Civil Infrastructure Systems Laboratory (CISL) of Kansas State University. CISL houses an accelerated pavement testing (APT) machine that is being used to apply 80-kN load on a single axle with dual tire to the test pavement sections. These sections get instrumented with asphalt pavement and other strain gauges, earth pressure cells, time domain reflectometry (TDR) probes, and thermocouples. The data collection is done using a new compact data acquisition system (cDAQ). The cDAQ system, manufactured by National Instrument, allows multiple interchangeable modules to be used with an electronic chassis and a simple USB interface with a personal computer. LabVIEW is used to set up the visual interface to collect and store the data. The paper discusses the step-by-step process followed in sensor installation, testing, data collection, and variability analysis in the experiment involving geocellular sytem-reinforced bases. The experience described here will be valuable for those designing and installing new pavement instrumentation.
