A clear definition of tar-and-chip, also called stoning or chip seal: how it is applied, what it looks like, and how it compares to standard asphalt.
Quick answer: tar-and-chip, also called stoning or chip seal, is a surface made by spraying hot liquid asphalt over a prepared base and then rolling crushed stone into it. The result is a durable, textured, natural-stone finish that is different from the smooth black look of standard asphalt.
Tar and Chip, Defined
Tar-and-chip is a stone-topped surface bonded with liquid asphalt. A layer of hot asphalt binder is sprayed onto a solid gravel base, then crushed stone is spread over it and pressed in with a roller. The stone locks into the binder as it cools, leaving a rugged surface with the color and texture of the stone itself. Contractors also call this process stoning, chip seal, or oil-and-chip. R. Stanley’s Paving offers stoning as one of our core services.
