THE EFFECT OF DYNAMIC LOADING ON ROAD PAVEMENT WEAR: A STUDY OF THE RELATIONSHIP BETWEEN ROAD PROFILES AND PAVEMENT WEAR ON AN INSTRUMENTED TEST ROAD

The Transport Operations Research Group (TORG), in collaboration with the Transport Research Laboratory (TRL), have established a test laboratory capable of monitoring the dynamic loading applied to road pavements by heavy goods vehicles. The following key conclusions have been formed: (a) The wheels of the test vehicles applied dynamic loading which oscillated at a frequency of approximately 3 Hz and appeared to be independent of speed, load, tyre type and suspension system; (b) Each of the axles of the test vehicles applied maximum and minimum dynamic loads at points of common chainage for a specific speed; (c) The ratio of mean dynamic axle-load and static axle-load increased with speed; (d) The dynamic-load coefficient appeared to have a local peak value between 50 and 80 km/h for the instrumented vehicle before increasing further with speed; (e) Relationships exist and have been developed between the dynamic load coefficient, road roughness and speed for each of the axles on the test vehicles; and (f) The implications of the results, which have been assessed for pavement design and the allocation of road track costs, are considerable.
