Typical Application Methods

 To Address Permanent Heavy Weight Traffic Area Requirements for the Following:

 Application Method 1.

1. Grade, contour and compact the soil to final elevations.
2. Till soil to the specified depth of treatment with a roto-tiller (i.e. 2 inches)
3. Spray-apply the required amount of properly diluted PolyPavement onto the loose soil.
4. Till the soil again to thoroughly mix soil and PolyPavement.
5. Re-compact the soil with a steel drum roller.
6. Spray-apply the required amount of properly diluted PolyPavement onto the compact soil surface.
7. Allow the soil to dry.

 To Address Temporary Light Weight Traffic Area Requirements for the Following:

 Application Method 2.

1. Grade, contour and compact the soil to final elevations.
2. Spray-apply the required amount of properly diluted PolyPavement onto the compact soil surface.
3. Do not allow the soil to dry.
4. Spray-apply the required amount of properly diluted PolyPavement onto the treated soil surface.
5. Allow the soil to dry.

 To Address Short-Term to Long-Term Non-Traffic Area Requirements for the Following:

 Application Method 3.

1. Spray-apply the required amount of properly diluted PolyPavement onto the existing soil.
2. Do not allow the soil to dry.
3. Spray-apply the required amount of properly diluted PolyPavement onto the existing soil.
4. Allow the soil to dry.

The U.S. Army Corps of Engineers tested this technology for performance in desert, tropic and temperate climatic zones. The technology met or exceeded all laboratory and field performance criteria specified for rubber tire vehicles and adverse weather in all traffic area and non-traffic area applications. (Reference: USACE Technical Report GL-93-25, September 1993, WES Geotechnical Laboratory)

 USACE PERFORMANCE TEST RESULTS

In September 1993, the U.S. Army Corps of Engineers completed the evaluation and comparison of the performance and cost of existing soil additive materials for traffic area and non-traffic area soil applications in desert, tropic and temperate climates. A total of 347 materials and methods were evaluated. Each material and method had to pass all of the Corps' laboratory test criteria to qualify for further testing under actual field conditions. The laboratory researchers tested all 347 materials and methods for:

1. Resistance to water erosion, sheet-flow and rainfall 2. Resistance to ultra violet rays from sunlight 3. Resistance to jet fuel spillage 4. Resistance to extreme heat 5. Resistance to simulated wind and prop wash air blasts

Only 7 materials of the total 347 materials and methods tested passed all of the laboratory test criteria and qualified for further testing under actual field conditions.

The field application tests were conducted under desert, tropic and temperate climatic conditions.

The test results showed PolyPavement (Sand/Dirt Glue) to be the only material that passed all of the Corps' criteria for traffic and non-traffic applications in desert, tropic and temperate climates. None of the other soil polymers met a single one of the Corps' field evaluation test criteria for traffic area or non-traffic area soil applications. In addition, PolyPavement was the only material and method that significantly reduced the manpower requirements and the cost for materials by 30% or more.

As a result of the U.S. Army Corps of Engineers tests and evaluation, PolyPavement is the only material recommended by the Corps of Engineers for all the following applications:

1. Traffic Areas, Desert Climates 2. Traffic Areas, Temperate Climates 3. Traffic Areas, Tropical Climates 4. Non Traffic Areas, Desert Climates 5. Non Traffic Areas, Temperate Climates 6. Non Traffic Areas, Tropical Climates 7. Low Manpower and Material Costs

The U.S. Army Corps of Engineers' extensive study and evaluation of all existing soil additive materials and methods demonstrated that PolyPavement is far superior to all other materials and methods for soil stabilization and soil solidification applications.
