A method and an apparatus for determining the resiliency of a road surface include a vehicle (1) that is caused to move along the road surface (3) and that exerts a load on said surface with one wheel (2). A ball of plastic material (16) is shot onto the road surface (3) so as to adhere thereto in the movement path of two measuring arrangements (8, 9; 18, 19) which are separated in the direction of movement of the vehicle (1) and by means of which the vertical distance is measured between the upper side of the ball (16) adhering to the road surface (3) and a vehicle-carried reference in two positions along the vehicle. The distance between the reference and the measuring body can be established in several positions along the vehicle (1), for determining the deflection curve of the road surface.

1. A method of determining the resilience of a road surface (3), wherein a vehicle (1) is caused to move along the road surface (3), and to subject said surface to a given force in a small loading area which follows the vehicle (1), wherein at least two measuring processes are carried out at one and the same measuring position on the road surface, wherein said two measuring processes are carried out at mutually different distances from the loading area, and wherein. said measuring processes are carried out by contactless detection of the distance between the measuring points (6) and a vehicle-carried reference, characterised by applying a measuring body (16) to the road surface and utilising the free surface of said body (16) as a measuring point (6).
