Cape Seal, Micro Surfacing Improve Runway, Pavements on Lake Erie Island

Cape seal and micro surfacing pavement preservation treatments were the best choice for improving a runway and township roads on Ohio’s isolated North Bass Island, in Lake Erie just two miles south of the Canadian border.

The project by Strawser Construction, Inc. — as designed and sold by the Ottawa County Engineer’s office — consisted of resurfacing the North Bass Island airport runway, and various township roadways across the island.

Based on the county’s pavement evaluation and considering the townships economic constraints, it was concluded at the time that the best repair methodology would be what is known in the pavement preservation arena as a cape seal, consisting of sealing the existing surface with a stress absorbing membrane interlayer or SAMI, followed by a single-course micro surfacing as the final riding surface.
