"We have to find a way to make our money go farther, and soil stabilization with the Asphalt Zipper is the best game we have found. I was skeptical at first, but the Zipper has totally exceeded my expectations."
– Jerry Sikes, Public Works Director, Suwannee County, FL
"With the Asphalt Zipper, we grind the material in place, add our soil stabilizer and it makes a wonderful base."
– Bob Johnson, Former Public Works Director, Glenn County, CA
"The Zipper is very affordable and has enabled us to stabilize our streets, not just treat the surface. We're doing a full-depth rehabilitation that is now a stabilized road and a long term repair."
– Terry Garrett, Retired Road Superintendent, Brownwood, TX
"The Asphalt Zipper is very good for stabilization. It's very efficient and it's very easy to train crews on."
– Dr. Curtis F. Berthelot, P.Eng., Associate Professor, University of Saskatchewan, SK, Canada
Easy and Affordable Soil Stabilization
Soil Stabilization is quick and easy with an Asphalt Zipper machine, efficiently blending just about any soil stabilizer additive into a uniform mixture. Asphalt Zipper machines are the portable, more affordable alternative to larger soil stabilization equipment and most soil stabilization methods. Easily incorporate crushed rock, cement, lyme, fly ash, liquid polymers, enzymes or just about any other dry or liquid stabilizing additive. Simply pulverize the area to be stabilized, uniformly spread stabilizing material and then blend with your Asphalt Zipper machine. This homogenous mixture is then ready to be graded, reshaped and compacted in preparation for a topcoat.
Pulverize asphalt or chip seal if present.* Inject water through spraybar.
Uniformly spread additional material or stabilizer (crushed rock, cement, fly ash, liquid polymer, enzyme, etc.).
Thoroughly blend material or stabilizer with a predetermined portion of the base. Hydrate as needed.
Grade and reshape. Hydrate as needed.
Compact with sufficient moisture.†
When cured it can be paved or sealed.
* Avoid rocks over 3 inches / 75 mm in size.
† Be sure to know the effective compaction depth of your equipment and compact in lifts if necessary. Better results are achieved using heavier vibratory compactors.
