How many gallons of enzyme are needed to stabilze 1 mile of 2 lane road 25 feet wide with a six inch base?

16 Gallons on average.

Is the enzyme expensive?

No, relatively speaking it is quite inexpensive. When you think about being able to remove the need for crushed rock or aggregate out of the road building equation you lessen the cost significantly. By removing altogether (or lessening in the case of a Super Highway) the need for crushed rock you eliminate many man hours and high costs that were dedicated to procuring the aggregate. You also remove many man and equipment hours that were dedicated to transporting the rock to the road site. This also contributes to an enzyme road having a significantly reduced carbon footprint.

How do Enzyme Roads hold up to heavy rainfall or flooded areas?

Enzyme Roads are much less susceptible to water adsorption. Permeabilities of less than 1 X 10(-6) cm/second are typically achieved on properly constructed Permazyme roads also resulting in nominal effects due to freeze-thaw cycles.

Is it possible to achieve the same compression strength in an enzyme road as a conventionally constructed road?

Even stronger. Compression levels exceeding 100 are typical with enzyme roads. Expected load bearing capacities with a properly constructed Enzyme enzyme road are as follows: 15 cm to 30 cm surface thickness – up to 9,000 kg wheel loads 30 cm to 60 cm surface thickness – 9,000 kg to 13,000 kg wheel loads

How do enzyme roads react to temperature extremes?

Enzyme treated roads have successfully withstood temperature ranges from 50 degrees Celsius + to –30 degrees Celsius with minimum cracking after rains and freeze-thaw cycles. PBS's enzyme treated soils resist the forces of freeze-thaw cycles due to the bonded, high density of the road material.

Can Enzyme be mixed with other organic materials?

PBS’s enzyme works well with all organic soils. PBS's lab prescribes the optimal soil blend to increase the bonding of the fines (-200 mesh) and allow greater moisture penetration to facilitate compaction. Enzyme has been used successfully in roads containing Limestone (CaO). Calcite (CaCO3) a fine grain limestone, and soft earth clay, also react positively with PBS’s enzyme, however the use of clays should be minimized in road building—usually less than 30% - 200 mesh.

How long before you can drive on an enzyme constructed road?

PBS’s enzyme treated soils achieve their greatest strength after compaction and subsequent curing period of (72 hours drying), after that the road is ready for traffic.However 24 hours for light traffic.
