"With the Zipper I don't have to saw-cut my utility trench or haul and dump my asphalt anymore. I just put the Zipper in the ground and go. The speed is unbelievable. The cost of the machine is no object because of how much it saves you."
– Mike Sanders, Owner, Central Backhoe, TX
"We're able to grind 1000 feet of utility trench, 9 feet wide, in 2 hours, that would normally take us 2 days. I can't think of another piece of equipment that has been as beneficial in keeping our costs down as the Asphalt Zipper."
– Frank Triplett, Retired Water Division Manager, Spokane, WA
"If you're not opening utility trench with an Asphalt Zipper, it's like having to ride a bicycle instead of driving a car."
– Ken Smith, Vice President, T.A. Loving, NC
"If you have a big utility trench job, you can't beat it. It's just one whole facet of the job we don't have to worry about; we just Zip it."
– Woody Mather, Owner, Mather Corporation, Bloomfield, CT
"Our guys can't even finish their coffee before it's time to start digging."

The Fastest and Least Expensive Way to Open Utility Trench
Asphalt Zipper® machines both cut and pulverize asphalt into reusable material, virtually eliminating saw cutting, chunking, trucking and disposal costs. For nearly 20 years Asphalt Zipper machines have been the quickest, most economical way to open utility trench in asphalt and have revolutionized utility trench projects. There is not a more productive or cost effective asphalt trencher for utility trenching on the market. In addition, the Asphalt Zipper machine creates a better bonding surface than a saw-cut edge for superior repairs.
Comparison - 300 Foot Trench
A 300 foot utility trench can take 8+ hours to saw-cut, chunk, excavate, load, haul, and dump vs. about 20 minutes to pulverize the same trench into material that can be reused in the trench as bedding or fill, with cost savings that are just as impressive.

Superior Straight Edge
University research has shown that the Zipper edge improves patch joint bond strength by 25 percent over a saw-cut edge.

Pulverized Reusable Material
"We took the Zipped material to our lab and found it was a spec-quality product."

T-Cuts and Insetting Trench Plates
Asphalt Zipper machines are also ideal for making T-cuts and insetting trench plates when necessary.
