About 1 hour

By “Zipping” instead of saw-cutting, chunking, loading, hauling, disposal, and backfill, a 1,000-foot trench that would typically take two or three days can be opened in about an hour, with approximate cost savings of $10,000, based on national averages of Asphalt Zipper machine owners.

Improves Joint Bond Strength

University research has proven that a scarified, interlocking ‘Zipped’ edge improves joint bond strength 25 percent over a saw-cut edge.
