Bolt-Hold Anchors

Posted on August 16, 2017

BoltHold special-purpose anchors are designed to be an economical and reliable way to attach structures directly to asphalt at a fraction of the cost of concrete replacement, according to the company. Even in thin asphalt, the pull resistance is up to 2,500 pounds; in heavier asphalt, it is up to 6,000 pounds.

An internal thread accepts a bolt that is used to attach the structure to the anchor. (The anchors are available with TRA threads.) The anchor bonds to asphalt using an epoxy or cement (or “grout”). An oversize hole is drilled in the asphalt, is filled with a fast-curing grout, and the anchor is dropped in until it is flush with the surface. The displaced grout is pushed into the crevices in the asphalt and in the gravel layer below. The grout binds to the anchor on one side, and the asphalt on the other side.

Common applications are mounting parking signs, fence posts, lighting fixtures, and speed bumps. The anchors can also be used for bus shelters and lights in a bus yard, according to the company.
