Abstract: Asphalt concrete pavement consisting of an asphalt surface course, concrete subbase of specified compressive strength fc? and modulus of rupture up to 5,000 and 750 psi, respectively, with small grains crushed limestone finer than 9.5 mm as a coarse aggregate, and a layer of granular material between the surface course and concrete subbase is considered as a semi-rigid pavement. Rigidity of this composite structure is provided by the concrete subbase whereas its flexibility is provided by the asphalt surface course resting on the layer of granular material.

Abstract: A golf club includes a clubhead having a striking face, a threaded cylindrical chamber behind and generally parallel to the face, and a threaded cylindrical weight member in the chamber. A hosel is attached to the cylindrical weight member and has a shaft receiving socket with a non-circular portion and a threaded portion, the shaft having a hosel engaging end with a mating non-circular cross section and a ferrule having threads engagable with the threaded portion of the socket. A second embodiment includes a clubhead which is symmetrical so that the hosel may be attached at either end to make the club ambidextrous. Some different structures for attaching the hosel to the cylindrical weight member provide for variations in the loft of the club. Another embodiment includes an asymmetric movable weight member which engages the head within a cavity therein and is adjustable both longitudinally and by changing the location of its center of gravity.
