Abstract: Geotechnical instruments, including inclinometers, piezometers, settlement plates, etc., have long been used during and after construction to monitor performance of transportation infrastructure, including roadways. Traditionally, most of the instruments were read manually. For example, an inclinometer was read by a technician in the field using a probe and a handheld readout unit. After collecting the data, an engineer in the office retreieved the data from the readout unit, analyzed the data using either a spreadsheet or software provided by the instrument manufacturer, and generated data plots for reporting.
