Instrumentation Data Interpretation

The use of embedded pavement instrumentation has been an important technology in the advancement of pavement engineering. Responses measured at critical locations in the structure enable engineers to develop a fundamental understanding of the interaction between pavement response and pavement performance. Virtually every road test or accelerated pavement test facility, with the exception of the WesTrack experiment, has utilized embedded instrumentation to gain valuable mechanistic-empirical information. While instrumentation has been used successfully, in-situ measurement of pavement response under dynamic wheel loadings can be a technically challenging and expensive task. Careful selection and installation of sensors are prerequisites for a successful instrumentation project. The selection of instruments depends upon the type of pavement and the objectives of the experiment. The instruments should be sensitive enough to produce the necessary data while reliable enough to ensure that dependable data can be obtained throughout the period of the experiment. This research provides guidelines for the sensor planning, selection, calibration and analysis required for a successful instrumentation project.
