ANCHORING TO ASPHALT
BoltHold is a family of anchors specifically designed for asphalt. The anchors are flush-mounted to the asphalt and provide a clean internal thread for attaching bolts to the anchors. All anchors are supplied with bolts and washers.
Installation requires drilling a hole and filling it with our grout (EPX2 or EPX3), then pushing the anchor in until it is flush with the asphalt surface. The grout hardens in 15 minutes allowing immediate installation. Full strength may take an hour. Anchors are rated for asphalt 2" (50mm) or thicker.
Here is a link to an article in American Fastener Journal titled Asphalt Anchors 101. It provides an extensive introduction to the do's and don't when it comes to fixing anything to asphalt.
We offer a choice of 2 materials (Carbon steel with Zinc plating or 304 Stainless Steel) and 2 standards of internal threads (Imperial (inch) and Metric). Our anchors will resist pullout forces ranging from 1,500 lb., to 5,000 lb in 3" asphalt, depending on the model. The resistance is much higher in thicker surfaces.
