Managing Data from Instrumentation in the CEDEX Test Track

One of the main objectives of test tracks is to determine the structural response of the pavements under particular load and environmental conditions. Structural response can be measured in terms of different variables, such as deflection, stress or strain at certain significant points of the pavement structure. Other related environmental variables as temperature or moisture condition are typically measured as well. A minimum number of sensors are required for any variable to be measured, as the variability of the response can be significant. Consequently, the number of sensors used in a pavement structural response assessment can be very high. Response is typically determined for different conditions of load, speed, offset, temperature, and number of cycles. This requires a very comprehensive planning for the measurements. This paper presents the Software Program used in CEDEX Test Track to measure and manage the data from the 6 pavement sections of the facility. The Program enables the planning of measurements for specified conditions of speed, offset, pavement temperature, date or number of cycles, and the later treatment of the registered signals. The Program can manage up to 256 sensors, and typically around 250.000 measurements are conducted in a complete test. This way, detailed knowledge of pavement behavior under a wide variety of environmental or load conditions can be achieved.
