The question of whether the problem of vehicle-generated pavement damage should be addressed in terms of the road-friendliness of suspension systems, or in terms of the road-friendliness of complete vehicle systems, has not yet been resolved. Three distinct phenomena came into play, namely, wheelbase-filtering, suspension cross-coupling, and spatial repeatability. These three phenomena are briefly described, and presented together with an assessment of the impact that each has on future decisions concerning the selection of practical road-friendliness performance evaluation methods. It is concluded that wheelbase filtering and suspension cross-coupling do not counter the implementation of the far more practical suspension-based performance evaluation methods, but that because of a spatial repeatability consideration, a vehicle-based performance evaluation method may be required.
