This paper describes a design model developed mainly for thin surfaced unbound gravel pavements, based on the pavement dynamic cone penetrometer (dcp). Utilizing developed parameters such as dcp structure number, pavement strength-balance and load sensitivity, the number of load applications to produce a 20 mm rut depth in the pavement under various drainage conditions may be predicted. The model was correlated against heavy vehicle simulator (hvs) results on a variety of relatively light pavements in South Africa. (TRRL)
