Asphalt Reclamation:
Asphalt Reclamation:
This new method for asphalt reclamation is the most exciting thing to happen in the road maintenance and repair field for as long as we can remember. Permazyme will revolutionize road repairs. A valuable benefit of this process over the years will be the prevention of asphalt material leaching into the earth due to the permanent bonding process of Permazyme.
As the oil currently used for asphalt becomes more and more scarce, it also becomes more expensive. This fact alone will require everyone in the road business to make some serious decisions about budget allocations. Cutting back on work needing to be done can only generate more deteriorated roads. So, we can continue to pass the buck and hand out the same old excuse that “we don’t have the budget money to make those repairs”. Or, the other option is to rethink the way we currently do business.
Everyone has preached for years about recycling more products, becoming as “green” as possible, and doing everything we can to erase our “footprints”. Most agencies have been stockpiling asphalt grindings for years, never having a cost effective method for reusing them.
We have a program that provides a method of utilizing those mountains of asphalt grindings. In addition, we are currently training people to recycle the asphalt “in place”. These methods are rapidly sweeping across the country. You will find that this is the most efficient, cost effective and permanent solution to those badly needed road repairs.
Here is how it all works:
Here is how it all works:
- When a base or sub base is the root of the problem, full depth reclamation is the solution. This is accomplished by using a grinding machine, such as the Asphalt Zipper for small repairs, or a Wertgen type grinder for road building, to grind through and pulverize the asphalt with base materials, while simultaneously injecting Permazyme. Once this material is thoroughly compacted in place, the failure will not reappear. Permazyme is a permanent and inexpensive solution to every base failure. There is no need to haul out material unless another overlay will go on top, then cut off just enough material so the overlay can be leveled with the adjoining roadway.
- The method for repairing failed asphalt is exactly the same, called asphalt reclamation. We have always known that Permazyme works well when asphalt grindings were mixed into the soil being treated. However, recently we discovered Permazyme works equally as well with asphalt grindings alone. We are now providing a method that will allow agencies to make repairs, in place, to failed asphalt. The old days of “mill and fill” are a thing of the past. When asphalt grindings are injected with Permazyme, they bond back together resulting in a product that is even denser and harder than the original. Simply grade the treated asphalt grindings back in place, wet with additional Permazyme and compact.
Imagine being able to repair rutted asphalt without hauling out old and bringing in new material. The cost of materials, time and effort saved by using these methods can be calculated easily. It means that the budget dollar will go many, many times farther. The only special equipment needed to accomplish either method is a machine to do the grinding.
What about the stockpiles of grindings?
What about the stockpiles of grindings?
Now that we know the effects of Permazyme on asphalt grindings, we are seeing more and more ways of utilizing the old grindings.
For example we can pre-inject Permazyme into asphalt grindings at the maintenance yard to take to the site of a pot hole or road failure. The end result provides a permanent repair and is much cheaper to use than cold mix. It will also set up harder and is much more durable than cold mix. You can make these and similar repairs for a few cents per foot instead of a few dollars per foot.
Road Shoulders:
Road Shoulders:
An area that continually causes everyone problems and is continually being overlooked is road shoulders. We are currently working with different agencies and teaching our method for reestablishing shoulders.
In many cases where shoulders have been neglected, we find there is a drop off of one to six inches. These areas are obvious traffic hazards and will eventually lead to road failure. This is a perfect area to utilize asphalt grindings. They can be incorporated into the road shoulder providing safer roadway and preventing erosion. This is an inexpensive method of providing safety and reducing liabilities.
Gravel Roads:
Gravel Roads:
Placing a thin lift of asphalt grindings (2”) over an existing gravel road and incorporating Permazyme into the mix will provide a solid wearing surface that readily accepts a chip seal or class 3 slurry seal for a durable inexpensive road. Even if the budget prevents a final surfacing, the treated mix will remain a serviceable road for years until surfacing can be funded. An additional benefit is a noticeable reduction in dust or particulate matter. Erosion is also decreased with this process.
Permazyme is certified Eco-Friendly. It is safe to handle in all situations and requires no specialized equipment.
