Abstract
A barrier includes recycled rubber portions molded around a core infrastructure. The core infrastructure may itself include recycled rubber in a containment body. The containment body may include baled recycled or other waste material. The barriers may be stacked or connected to form a barrier structure useful in environmental control and other applications. The method for making the barriers includes molding rubber portions and a binder around a core infrastructure.
Claims17
A barrier structure comprising:
- a rigid containment body comprising steel, the rigid containment body defining a hollow portion enclosed by the rigid containment body, the rigid containment body providing a core infrastructure;
- a filler material within the hollow portion, the filler material not compressed and having a density of 20-35 pounds per cubic foot (lb/ft3), the filler material including tire shreds/chips;
- and
- a layer molded around the rigid containment body, the layer including recycled rubber crumb and a binder, the layer compressed against the rigid containment body, wherein the binder comprises a polyurethane resin and the layer molded around the rigid containment body has a thickness of approximately 2 inches, wherein the layer molded around the rigid containment body comprises 1% to 15% binder by weight of the recycled rubber crumb and the barrier structure further comprises 1% water by weight of the binder.

A molded barrier structure comprising:
- a layer of recycled rubber particles;
- a binder adhering the recycled rubber particles together to form a skin;
- a rigid containment body comprising at least one of metal, plastic, composite material, concrete, pressed recycled material, and baled tires, the rigid containment body enclosing a void space, the skin formed around the rigid containment body, the rigid containment body providing a core infrastructure;
- the skin including a substantially smooth exterior surface;
- whereby the void space is at least partially filled with a filler material and the skin compressed against the rigid containment body, wherein the binder comprises a polyurethane resin and the skin formed around the rigid containment body has a thickness of approximately 2 inches, wherein the skin formed around the rigid containment body comprises 1% to 15% binder by weight of the recycled rubber particles and the molded barrier structure further comprises 1% water by weight of the binder.
