Scaled physical modelling of ultra-thin continuously reinforced concrete pavement

Fly-by-Pi: Open source closed-loop control for geotechnical centrifuge testing applications

“…Despite advances in numerical modelling, physical models serve as an external calibration measure to validate numerical results especially for experiments that present complex interaction phenomena not suited for current software applications. Active areas of research interest pursued at the University of Pretoria include modelling of pipe deflection as a function of sinkhole development [2], cavity propagation [3] in sinkhole and cave mining applications [4], small strain stiffness measurements [5], cyclic loading of railway embankments [6] and ultra-thin continuously reinforced concrete pavements (UTCRCP) [7].…”

“…As the complexity and duration of experiments have increased during the last few years, so has the demand for customisable, low-cost and programmable actuators and control systems [7,9]. In the context of open-source hardware and software solutions, augmented by the proliferation and wide availability of powerful, low-cost microcontroller and microprocessor platforms, such a solution can be readily engineered.…”
