Appl. No.:

13/277318

Inventors:

Glenn Robinson - Camden AL, US
William H. Moorhead - Smithfield VA, US

Assignee:

PCI-TRAMMCO, LLC. - Camden AL

International Classification:

E01B 1/00

US Classification:

238 2, 238 7

Abstract:

Systems and related methods involving isolation tubs are provided. In this regard, a representative system includes: an isolation tub formed of fiberglass reinforced plastic resin, the tub defining a reservoir; concrete positioned within the reservoir; and rails extending across the tub and being supported by the concrete, the rails being spaced from each other to form a special trackwork (STW) assembly.

Appl. No.:

16/717529

Inventors:

Glenn Robinson - Camden AL, US

International Classification:

E04G 23/02
E04B 1/66

Abstract:

The bottom of an expansion form is carved to approximately match the contour of the bottom of a crack or joint, while the top is allowed to “run wild” above the surface level. A generous bead of flexible caulk is applied to the bottom of the crack or joint and the expansion form is gently pressed into the caulk to seal the bottom of the expansion form to the bottom of the crack or joint. The damaged area is backfilled and graded, and the top of the form is trimmed after backfill sets. The lower portion of the expansion form is made from a closed-cell polyethylene foam board with sawed sides, which opens the cells to improve the adhesion of the expansion form to the backfill material. Lateral blocking may be used to support the expansion form upright and following the joint or crack while the backfill sets.

Glenn Robinson - Camden AL, US

International Classification:

E01C 23/09

Abstract:

A joint form is positioned in a damaged expansion joint to allow both sides of the joint to be repaired at the same time. The joint form remains as a permanent part of the repair, which avoids the time consuming conventional process of removing temporary forms, cleaning the repaired surfaces, and inserting an elastomeric seal into the expansion joint. Type-0 joint forms include a block-seal laminate including a foam block layer (e.g., closed-cell polyethylene) laminated to an upper elastomeric seal layer (e.g., closed-cell neoprene) without a stiffener board. Type-1 joint forms include a block-seal laminate with a stiffener board (e.g., fiberglass reinforced plastic or FRP) adhered to one side of the block-seal laminate. Type-2 joint forms include a pair of block-seal laminate panels on either side of a central stiffener board bonded to one side laminated to an upper seal layer. Joint forms may also be utilized to seal undamaged expansion joints.
