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 method for treating a joint of pavement, comprising:
- applying a hardener/densifier to opposed inside surfaces of a joint between adjacent sections of pavement;
- and
- applying a coating to the opposed inside surfaces of the joint, the coating comprising:
- a silane, a siloxane, and/or a silicone.
A pavement joint, comprising:
- a first pavement element including a first pavement surface and a first end surface, the first end surface defining a first joint surface;
- a second pavement element including a second pavement surface and a second end surface, the second end surface defining a second joint surface, the first end surface and the second end surface facing each other and defining inside surfaces of the pavement joint;
- a reaction product of a hardener/densifier and concrete on the first joint surface and the second joint surface;
- and
- a coating on the first joint surface and the second joint surface, the coating comprising:
- a silane, a siloxane, and/or a silicone.
A composition, comprising:
- a hardener/densifier;
- and
- silane solids dispersed throughout the hardener/densifier.
A method for protecting a joint in pavement, comprising:
- providing a seal in a joint in pavement;
- and
- after providing the seal in the joint, applying a hardener/densifier to the joint and over the seal in the joint.
