Can Asphalt Anchors be used without adhesive?

No.

An anchor’s strength comes from the adhesive bonding the anchor to the asphalt. Unlike concrete, asphalt needs both an anchor designed for it and the right adhesive.

Our anchors install into an oversize hole, where the anchor drops in cleanly. The adhesive fills the gap and bonds the anchor to the asphalt. See EPX2 vs EPX3 Adhesive to choose one.
