The issue as we see it is that most people look at the pavement and think “ROAD” because that is what shows. With this attitude the end result is that they end up relying too much on the pavement without considering the other more important aspects that should go into any paving project.
As has been discussed many times before a road is not solely pavement! A road is a system of which the pavement is the top part (much like the roof on a house is the top of a complete system of foundation, frame, walls, roof, etc that make up the whole).
In order to provide a pavement (which is what we are creating with the Polymer Pavement System) having good functionality and good lifespan we need first to ensure good base and good drainage, thus we do NOT rely on the pavement for strength but rather for “consolidation of the surface aggregate” such that there is no mud in the wet season and no dust in the dry season.
If this surface to be paved requires better load bearing, this can be accomplished using Geosynthetics. The side benefit of the Geosynthetics is better drainage as well (we have many photos of GeoCell to share if it is deemed helpful/useful).
In conclusion we can rely on 2 – 3 inches of pavement (polymer, asphalt or concrete) to support nearly any load if the base and subgrade are stable and well drained. We cannot rely on 4 inches or more to support any load if the base and or subgrade are poorly stabilized or poorly drained.
A road is not as simple as flattening some pavement in place and calling it a day. There’s more to a road than it’s pavement, and if you’re not thinking about that at the outset, you’re bound for trouble post-pour and level.
Things to consider prior to a pavement dump include what it is your pouring the pavement on. Seriously, what’s in the terrain? Where is the terrain? What are the challenges associated with the surrounding ecosystem? What’s the drainage situation in the event of any environmental runoff? What’s under the terrain you’re pouring on?
There are many questions. There are also many answers.
At Global Environmental Solutions, we take to the art of road building seriously. And, we’re serious when we use the word “art.” Because it is. It’s not as easy as what we’ve already mentioned above. You can’t just dump a load of pavement and flatten it out with a roller. There’s a science and craft element to the entire initiation. And, there exists another important question… What’s in the aggregate that makes up your pavement? Do you even know?
Enter GES’s revolutionary DGE Polymer Pavement System which was formulated for the purpose of creating a hard stabilized surface for:
- Parking lots
- Tertiary gravel roads
- And much, much more…
“System” is the operative word there. You need a marriage of many factors in the construct of the idea “road.” It goes well beyond the surface…
Appropriate steps for DGE Polymer Pavement System are as follows:
- Ensure good drainage.
- Ensure a well stabilized base.
- Ensure proper aggregate with correct particle size distribution including 20% – 25% fines (material passing #150 sieve).
- Loosen the aggregate in the area to be treated.
- DirtGlue® polymer will be applied at a rate of not less than 0.03 gallons per sq. ft. per inch of pavement thickness as calculated before diluting with water. After making calculations dilute the DirtGlue® polymer with approximately one part water (a slight amount more water may be added later if you determine that the aggregate is too dry).
- Add the appropriate amount of TerraDry® (if required because of soil/ aggregate type).
- Apply the blended liquid (polymer and water) to the aggregate and mechanically mix in thoroughly and evenly. Depending upon type of equipment used this could take two or possibly three applications to get all of the liquid into the soil/aggregate. Keep mixing thoroughly and evenly 2 – 3 inches deep!
- Once the aggregate is treated with full amount of the product(s) specified and the product(s) are mixed in completely then level and compact.
- Proper curing requires warm temperatures. Do not apply when temps are below 55 or when rain is imminent. Typically, the warmer the better to ensure fast curing.
The DGE Polymer Paving System has similarities to asphalt paving.
Asphalt is made up of aggregate (in USA percentages by weight are approximately 94-1/2% linear gradation crushed rock and 5-1/2% tar as the binder and percentages by volume are about 17% tar to 80% aggregate – realize also that about 1/6 of that 17% asphalt is made up of solids).
The DGE PPS uses polymer as the binder and since tar is waterproof we add a bit of
TerraDry® to act as waterproofing agent to help the polymer.
In the PPS, a much lower percentage of polymer is required as the binder. This means more void space in the aggregate which needs to be filled with “fines” thus the increase in percentage of the particle size of 0.1mm (#150 sieve) and below.
Creating a sound, well-rounded and stout pavement system is no menial task. Let’s talk through it and pound pavement as one.
