Paved Road Construction Steps

Many different top coats can be applied to the soil once treated with Perma-Zyme such as asphalt, chip seal, and cement. In applications where a top coat is being applied follow the guidelines below.

Commence Construction

Be sure that the weather does not call for rain and that the temperature is above 45oF. 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.



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 ensures that the soil is uniformly moistened and the Perma-Zyme will be uniformly applied.


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.

Let the Permentation Process Begin

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

Note: You must have completed the unpaved application process before proceeding to the paved road application process. You would only move on to this final step if you were looking to turn your newly constructed unpaved into a paved road. Do not begin until the unpaved road has cured for the total recommended 72 hours.

Moisten the cured unpaved road

Prior to the application, you would wet the soil lightly with a highly diluted mix – 10,000 parts water to 1-part Perma-Zyme to allow the soil and top coat material to bond and adhere.

Apply Top Coat

Day 10+ – (____) Allow time for top coat material to fully cure according to manufacturer’s guidelines.
