STATE-OF-THE-ART REPORT ON FIELD INSTRUMENTATION FOR PAVEMENT EXPERIMENTS

The various instruments available for taking in situ measurement of stress, strain, deflection, temperature, pore pressure, soil suction, and axle load in pavement experiments are described. Discussion of the desirable objectives of pavement experiments and comments about instrumentation concerning the unavailability of general purpose equipment and the need to design instruments for specific applications are presented. Earth pressure cells are discussed and information is given on the theory of their in situ performance, design considerations, and installation procedures. The need for correct calibration is emphasized. Pressure cells that have been used in various projects are described as illustrative of the kinds of instruments that can be used. A detailed design procedure for the simplest type of cell and a discussion concerning the use of charts to assist with the calculations are provided. Strain measuring devices for use in soils, granular materials, and asphalt materials are described and comments are made on the relative merits of each. Even though there is a lack of available information about other instrumentation, the current state of the art is described for each case presented.
