  • Methods of setting roadmaking material and smoothing screeds for performing such methods
    Patent number: 4364690
    Abstract: A smoothing screed is used with a road finishing machine for setting roadmaking material when the surface of a road pavement, which has been damaged by tracks or depressions worn therein, is renewed. The smoothing screed is of adjustable width and profile and has a central main screed from which adjusting screeds may be drawn out laterally. There is further provided a central ridge profile adjustment device, which allows the central portion of the main screed to be adjusted so as to be lower than the ends of the main screed, and two further adjustment devices at the ends of the main screed, which allow the outer ends of the adjusting screeds to be adjusted so as to be lower than the ends of the main screed.
