Benefits of technology

[0017]Preferably, the frame members are made from injection of a high density polyethylene or HDPE structural foam into the mold. During the cutting process,

Problems solved by technology

Unfortunately, the steel in dowels has a tendency to corrode after years of use and this corrosion negates its beneficial incorporation.
While composite or fiberglass materials have been used to replace the steel dowels in the prior art, such incorporation also presents problems.
For example, these fiberglass or composite materials can no longer be welded to their support structure.
This requires extensive labor to assemble all of the compo

Embodiment Construction

[0031]The present invention will be described as it applies to its preferred embodiment. It is not intended that the present invention be limited to the described embodiment. It is intended that the invention cover all modifications and alternatives, which may be included within the spirit and scope of the invention.

[0032]Referring to the drawings, FIG. 1 illustrates the preferred embodiment of the improved road basket 10 of the present invention. Preferably, the road basket 10 includes a plurality of non-metallic dowels 12. The dowels may be made from any desired non-corrosive material. Preferably, the dowels 12 are made from fiberglass or a glass fiber reinforced polymer that provides flexibility. The non-metallic dowels 12 are generally held in an elevated position by a frame 14.

[0033]As shown in FIGS. 1-12, the frame 14 secures multiple dowels parallel to each other and parallel to the ground simplifying installation of the dowels in a slip form paving process. Preferably, the f...

Abstract

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation-in-Part of U.S. patent application Ser. No. 13 / 826,588 filed Mar. 14, 2013, herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]This invention relates to a composite dowel basket for use generally in jointed plane concrete pavement applications and a method for making the same. More specifically, though not exclusively, the present invention relates to a composite dowel basket in which the dowels themselves are secured in place during the molding process such that no on-site assembly is required. Optionally, support frames may be molded separately from the dowels, wherein the dowel ends are slidably inserted into the support frame for assembly. The assembly is easy to use, lightweight and non-corrosive.[0003]Currently, reinforced concrete employs a system of dowels which is supported by a wire support structure to elevate the dowels to a desired height within the poured conc...
