INDUCTIVE TECHNIQUE FOR DETERMINING LATERAL POSITION OF TEST WHEELS ON ROADS

An electronic device is described which provides a continuous record of lateral displacement of a test-vehicle wheel from a line within a range of plus or minus 100 mm and with an accuracy of plus or minus 5mm. This information is required when recording the amplitudes of transient stresses, strains and deflections in experimental road structures produced by a loaded wheel. The output signal from the device is displayed on the same chart as the recorded stress, strain and deflection signals. The device has been developed for use on flexible pavements. It has not been tested on, and is probably unsuitable for, concrete pavements containing steel reinforcement. /Author/
