    • A pavement slab including top and bottom surfaces, first and second longitudinal side surfaces, and first and second transverse side surfaces. The slab includes a first and second plurality of transverse holes formed within the first and second longitudinal side surfaces, respectively, a first and second plurality of longitudinal holes formed within the first and second plurality of transverse holes, respectively, and plurality of dowel bars. Each of the holes is sized and shaped to receive slidably a corresponding one of the plurality of dowel bars. Each of the dowel bars is slidable between a retracted position and an extend position in which the dowel bar forms a joint between the slab and another slab or preexisting pavement.

    • An improved road basket including a non-metallic dowel, a first support frame including a first support frame first leg and a first support frame first cup moldably secured to the dowel first end, and a second support frame including a second support frame first leg and a second support frame first cup moldably secured to the dowel second end. Multiple dowels can be secured in similar fashion to additional leg members. Preferably, the first support frame first leg and a first support frame second leg are connected by a base frame member. In addition, the first support frame first leg and the first support frame second leg may be connected by an intermediate frame member. The frame may be constructed of a single piece. The dowel is preferably made from fiberglass or glass fiber reinforced polymer and the frame is preferably high density polyethylene.

    • A conduit for the formation of pervious pavement includes a first connector and a second connector joinable to the first connector. The first connector includes a pair of first receiving notches. The second connector includes a pair of second receiving notches oriented perpendicular to the first receiving notches. When the first and second connector are joined to one another, the pair of first receiving notches cooperates with the second connector to define a pair of first attachment openings for receiving a first structural member of a reinforcing mesh, and the pair of second receiving notches cooperates with the first connector to define a pair of second attachment openings for receiving a second structural member of the reinforcing mesh. First and second tubes are inserted into the first and second connectors to complete the conduit assembly.

    • A structure is described for supporting concrete reinforcement bars in a concrete structure, such as a footer or foundation. The structure includes a base member having a lower surface and an opposing upper surface. A plurality of pairs of opposing first leg members extend upward from the upper surface of the base member. Each of the first leg members have a lower end connected to the base member and an upper end distally disposed from the lower end. The structure includes a plurality of cradles for receiving the reinforcement bars, where each cradle is attached to the upper ends of a corresponding pair of the opposing first leg members. In a preferred embodiment, the structure includes horizontal support members disposed between and connecting the cradles. To retain the reinforcement bars within the cradles, preferred embodiments of the structure include retaining members that protrude inward from the inner surfaces of the opposing sidewalls. These retaining members offer interference to any upward movement of the reinforcement bars. Preferably, the base member, opposing leg members, cradles, retaining members, and horizontal support members comprise a unitary structural element, such as a continuous piece of thermoplastic material formed by injection molding.
    • 描述了一种用于在诸如页脚或基础的混凝土结构中支撑混凝土钢筋的结构。 该结构包括具有下表面和相对的上表面的基底构件。 多对相对的第一腿部构件从基部构件的上表面向上延伸。 每个第一腿构件具有连接到基部构件的下端和从下端向远侧设置的上端。 该结构包括用于容纳加强杆的多个托架,其中每个托架附接到相应的一对相对的第一腿部件的上端。 在优选实施例中,结构包括设置在支架之间并连接支架的水平​​支撑构件。 为了将支撑杆保持在支架内,该结构的优选实施例包括从相对侧壁的内表面向内突出的保持构件。 这些保持构件对加强杆的任何向上运动都产生干扰。 优选地,基部构件,相对的腿构件,托架,保持构件和水平支撑构件包括整体结构元件,例如通过注射成型形成的连续热塑性材料片。
