The dynamic tyre forces generated by heavy goods vehicles are measured with a portable load measuring mat and used to investigate ‘spatial repeatability’. The mat is 56 m long, 13 mm thick and has 141 capacitative strip sensors, spaced at 0.4 m intervals. Two sets of experiments are described. In the phase 1 experiments the measured dynamic tyre forces generated by fourteen articulated vehicle combinations (three tractors and five trailers) are used to confirm previous theoretical predictions of spatial repeatability. In the phase 2 experiments the dynamic tyre forces generated by over 1500 heavy goods vehicles travelling on a British trunk road are used to estimate the degree of repeatability exhibited by a typical highway fleet.

    Spatial repeatability is assessed using the ‘spatial repeatability index’ (SRI), and a method is developed to correct the SRI for sensor noise. Approximately half the vehicles tested were found to contribute to a spatially repeatable pattern of road loading.
