A paver has a chassis and a trailing floating screed which is articulated on the chassis by a pair of tension arms. The setting angle of the screed relative to the ground is capable of being adjusted via actuating cylinders. The screed includes at least one tamper bar that is movable in upward and downward directions by a drive and having a variable number of strokes. Further, the screed has a bottom-side smoothing plate. At least one sensor configured for measuring the setting angle is provided in the vicinity of the rear end of the screed. The sensor is connected to an associated controller which is capable of adjusting the number of strokes or stroke rate of the tamper bar in order to adjust the setting angle of the screed to a predetermined desired value.

[ I claim:] [1.]1. A paver comprising a chassis and a trailing floating screed articulated on the chassis via tension arms and of which a setting angle relative to a ground surface is capable of being adjusted via actuating cylinders and which includes at least one tamper bar, the tamper bar being movable in upward and downward directions by means of a drive and having a variable number of strokes, and a bottom-side smoothing plate, wherein at least one sensor for measuring the setting angle is provided in the vicinity of a rear end of the screed, the sensor being connected to an associated controller configured for controlling the number of strokes of the tamper bar in order to adjust the setting angle to a predetermined desired value.
