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.

Thermoplastic compositions useful for sealing longitudinal joints of substrates, for example, roadways and pavement, are provided herein. Formulations including the composition and methods of using the thermoplastic composition to seal longitudinal joints are also disclosed.

Methods for sealing cracks and expansion joints comprising the use of an adhesion promoter. In certain embodiments, the adhesion promoter comprises a vinyl polymer.

A method of installing mastic joints on a paved surface is described. The method of installing mastic joints may be used as a repair (i.e. erosion of the paved surface at the joint) or in connection with a new installation of the paved surface. The method of installing mastic joints made include installation with joints that have a structure at the joint terminus. The method produces a joint that is resistant to infiltration of water, fuel, and salt, including mixtures thereof. The method further produces a mastic joint that is thermally resistant and produces longevity of use.

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.
