Abstract: A self-propelled power roller screed having two generally parallel tubular screed tubes and powered winching means that cooperatively engage winching cables attached to deadman structures to advance the roller screed.

Abstract: The present application relates to methods for laying a traffic calming surface, in which molten material is deposited on the surface of a road or path and is then moulded so as to form a continuous, substantially sinusoidal profile which extends along the intended direction of travel. The profile can be formed by employing at least one pair of longitudinal rails which are positioned on the surface of the road so as to be spaced apart from each other and such that they are aligned with the intended direction of travel. The upper surface of the rails exhibits the required profile so that molten material deposited between the rails can be spread between the rails to form the required surface.

Abstract: Methods and apparatus for power finishing freshly placed concrete in which the acoustic impedance of the treating equipment is made substantially equal to the acoustic impedance of the concrete slab being treated. Preferably, a powered, twin rotor riding trowel is provided with a pair of circular finishing pans that are attached to the conventional rotor blades used later in the finishing process. The pans are characterized by an acoustic impedance approximating the acoustic impedance of green concrete, thereby optimizing the energy transferred to the concrete. Preferred pans comprise ultra-high molecular weight polyethylene (UHMWPE) plastic. During troweling, the pans are frictionally revolved over the green concrete for finishing the surface without prematurely sealing the uppermost slab surface. Through the disclosed troweling method, a highly stable concrete surface results, and delamination is minimized. Alternative troweling uses pans coated with layered impedance matching material.

Abstract: A powered rotary screed provides a powered strike tube that rotates to provide a finish to wet concrete during screeding and a drive tube that provides motive power to the screed to assist with the difficult task of removing excess concrete from a poured pad, or other horizontal concrete surface.

Handles are pivotally coupled to plates at each end of the screed to maneuver and control the screed during operation. Because the handles are pivotally mounted, they can be pivoted outward to permit the screed to maneuver close to obstacles located near the pad.
