Perma-Zyme® Soil Stabilizer For Road Construction

What is Perma-Zyme®?

 
Perma-Zyme® is a proprietary enzyme-catalytic compound that is developed for soil stabilization, roadway construction, and water lining applications with cost savings up to 80% compared to traditional construction cost.

Perma-Zyme-Enzymatic-Soil-Stabilization-Solution-for-road-construction.pngPerma-Zyme® provides catalytic bonding with clay particles producing high-density concrete-like dirt road surfaces, or as a strong foundation for conventional road pavement and construction.

It is supplied in a highly concentrated liquid form for easy application and outstanding results compared to polymer soil stabilizers.

Why is Perma-Zyme® the best solution for soil stabilization and road constructions?

  • Highly effective enzyme-based soil stabilizer

  • Supplied in highly concentrated liquid form

  • Exceptional efficacy and cost savings when used in unpaved road constructions.

  • Extends the life of unpaved roads up to 10 years with little to no maintenance

  • Prevents seepage and erosion and doesn't wash with rain as alternative polymers do

  • Reduce construction costs by up to 80% when used in paved roads

  • Decrease or eliminate base course in paved roads construction

  • Decrease or eliminate the need for asphalt in rural roads

  • Longer lasting roads with a base that is more resilient compared to traditional construction methods without Perma-Zyme®

How Perma-Zyme® Works

 
  • ​Perma-Zyme® increases the wetting action of water, facilitating improved penetration in and out of the prepared layer without leaving cavities behind. It draws the water-suspended clay to fill the treated soil voids, and the clay bonds with the aggregate, creating high density and exceptional strength.
 
  • Perma-Zyme® catalyzes the soil organic components, forming an intermediate reactant ready for bonding with the negatively charged clay particles. When the clay soil and Perma-Zyme® meet, an electrochemical reaction occurs, and the particles permanently bond the particles together, forming a shrink and swelling resistant, waterproof surface.
     

  • Curing and setting generally occur within 72 hours, but the bonding process continues for about six weeks. Perma-Zyme® treatment alters the index and engineering properties of the soil, giving enhanced shear strength, optimized liquid limit (plasticity vs. liquefaction state), and increased coherence in a concrete-like soil layer.
     

  • Perma-Zyme® also improves the lubricity of the treated soil, making it much easier to compress, which yields an outstanding compressive strength. The in-site testings also showed excellent performance in freeze-thaw environments.
     

  • The Perma-Zyme® enzyme is completely biodegradable, which dissipates safely after the process completion with no environmental impact.

How To Use Perma-Zyme®

Simple and Easy Steps To Build A Road With Perma-Zyme®

Perma-Zyme®​ Application Preparations:
 

 
Required Soil ASTM Testings

  

Soil-Type-For-Perma-Zyme-Application.PNG

  • ​ASTM C117, C136- Sieve Analysis: ​​​​​​​​​

    The ASTM C117 and C136 are standard sieve analysis tests. It is necessary to have a sieve analysis done prior to the Perma-Zyme application to ensure that the soil has at least 15% passing the #200 sieve as soils with less than 15% are NOT compatible with the product. It is also ideal to have a distribution of different sieve sizes inside the soil as it enables improved bonding for Perma-Zyme.​​
     

  • ​ASTM D1557- Proctor Test: 

    The ASTM D1557 (Proctor Test) is an essential test to measures the soil's optimum moisture content. The moisture content ensures the optimum efficacy of Perma-Zyme and that the soil will reach the required density and strength once cured.

 

Project Conditions and Design Recommendations

   

Perma-Zyme® is designed to harden soil particles into cement-like material while improving dust control. See below the details of the recommended conditions:

  • ​Weather Recommendation:
    It is best to apply Perma-Zyme ®in the warmer seasons; Perma-Zyme cannot be applied when the temperature is under 40°F. During application, ensure that there is no rain in the forecast for at least 72 hours.

  • Typical ​Lifespan:
    The typical lifespan of a Perma-Zyme treated road is 10-15 years. Typical road wear can be observed depending on traffic, climate, or constant water flow. Topcoat extends the Perma-Zyme treated roads since the surface is not being used as the primary exposed surface.

  • Depth Recommendation:
    The recommended depth varies depending on the application of the road as follow:
     

    Very light traffic, Temporary road: 3"
    Regular traffic, Unpaved or paved road: 6"
    Heavyweight traffic, Unpaved or paved road: 9-12"
  • Topcoat (Road Paving): 
    Many different topcoats can be applied to the soil once treated with Perma-Zyme, Road-Pavement-Topcoat-Perma-zyme-Soil-Stabilizer.PNGsuch as asphalt, chip seal, and cement.
     

  • In projects where a topcoat is being applied, please allow extra time for the road to be fully cured.

     

Unpaved Road Construction Steps and Use Recommendations:


Unpaved-road-application-steps-for-Perma-zyme.PNG

 
Perma-Zyme® Use Recommendation for Unpaved Roads:
 

  • Dilution || 1 pound per 18 cubic yards
  • Soil Requirements || 15-20% cohesive fines
  • Operating Temperature || 50° F to 115° F
  • Set Time || 4 Hours
  • Curing Time || 72 hours
 

Commence Construction​​:

  • Be sure that the weather does not call for rain and that the temperature is above 40°F.

  • Excavate your future road by using a grader to rip and mix the soil. Ensure the soil has been excavated to the desired depth of the road.

       

​Equipment Needed:

  • Grader
  • Water Truck
  • Sheepsfoot Compactor
  • Smooth Wheel Roller
 

Apply Perma-Zyme®:

  • Using a water truck, mix Perma-Zyme, and water. Then, spray the soil with the mixture.
     

Mix the Soil:

  • For best results, use a blade attachment to mix the soil by blading the soil from side to side and up and down the path. This process is to ensure uniform hydration of the soil for an even and effective Perma-Zyme application.
     

Compaction:

  • Using a compactor, ideally, a sheepsfoot compactor, begin compacting the soil in 3-6 inch lifts. Once the soil has reached nearly optimum compaction, it is best to use a drum compactor to complete compaction and level it.
     

Curing:

  • Once the road has been compacted, the road is ready for light traffic. The soil will be fully cured within 72 hours.
 

Paved Road Construction Steps and Use Recommendations:

Compaction and Curing

  • Using a compactor, ideally, a sheepsfoot compactor, begin compacting the soil in 3-6 inch lifts. Once the soil has reached nearly optimum compaction, it is best to use a drum compactor to complete compaction and level it.

  • Once the road has been compacted, the road is ready for light traffic. The soil will be fully cured within 72 hours.
 

Moisten the cured unpaved road:

  • Before starting the paved road process, wet the soil with a 1 part Perma-Zym to 10,000 parts water for improved surface bonding prior to the topcoat application.


Apply Top Coat:

  • For optimal results, allow more than ten days for topcoat material to cure fully.
