Abstract
A technique for protecting joints in pavement structures includes applying a hardener/densifier to one or more surfaces that define a joint in a pavement structure and, optionally, to portions of one or more surfaces that are located adjacent to the joint. One or more other compounds, such as hydrophobic materials, water-resistant materials, anti-scaling compounds, anti-wear compounds, multi-functional blended compositions and the like, may also be applied to the surfaces that define a joint and/or to portions of one or more surfaces that are adjacent to the joint. A seal may also be formed in a joint in a pavement structure. Joints that have been protected in accordance with teachings of this disclosure are also disclosed.
Claims20
A joint in concrete, comprising:
- adjacent sections of concrete with opposed surfaces defining the joint;
- a reaction product of a hardener/densifier and the concrete on the opposed surfaces;
- and
- a coating on the opposed surfaces, the coating comprising:
- a silane, a siloxane, and/or a silicone.
A joint in concrete, comprising:
- a first section of concrete including a first outer surface and a first end surface, the first end surface defining a first joint surface;
- a second section of concrete including a second outer surface and a second end surface, the second end surface defining a second joint surface;
- a reaction product of a hardener/densifier and the concrete on the first joint surface and the second joint surface;
- and
- a coating on the first joint surface and the second joint surface comprising:
- a silane, a siloxane, and/or a silicone.
A joint in concrete, comprising:
- a seal in the joint in the concrete;
- a hardener/densifier or a seal reaction product of the hardener/densifier and the seal on the seal;
- and
- a concrete reaction product of the hardener/densifier and the concrete on the joint, the hardener/densifier on the seal.
