Perma-Zyme® Q&A

Is there any effect when Perma-Zyme is mixed with any other organic material e.g. CaO or CaCO3?
Perma-Zyme works well with all organic soils. It will increase the bonding of the fines (-200 mesh) and allow greater moisture penetration to facilitate compaction. Perma-Zyme has been used successfully in roads containing Limestone (CaO). Calcite (CaCO3), a fine grain limestone or soft earthy clay, also reacts positively with Perma-Zyme, however the use of clays should be minimized in road building - usually less than 30% -200 mesh.

As time goes on will Perma-Zyme reduce or increase its bonding strength? Will the road come out with cracks or become fragile?
Perma-Zyme treated soils (for roads or ponds) achieve their greatest strength at the time of compaction and immediate subsequent curing (72 hours drying). Bonding of the soil particles takes place in the presence of moisture and comp active force. This condition will last as long as the material resists external forces. Heavy wheel loads, water, freeze-thaw cycles ultimately have an effect on all roads. Perma-Zyme treated soil resists these forces due to the bonded, high density of the road material. The road will resist the detrimental effects of erosion and mechanical forces.
Cracking occurs as a result of two factors: (1) If the road material contains a high percent of expansive clays - having a high shrink-swell factor. When the road is completed and dries out some cracking will appear. This reduces the effectiveness of the roads stability, however we have seen roads showing this condition that have performed very well - but with reduced life. (2) Soft sub-base may not support the treated base under wheel loads i.e. expansive clays. The bearing capability of the road is insufficient. This is corrected by increasing the thickness of the road base.
When the Clay fines (minus 299 mesh) exceed 25% or are highly expansive some surface cracking will occur. Generally the cracks are superficial, often filling in with road particles during normal traffic use. Generally this condition is referred to as "Alligator Cracking" and does not significantly affect to stability of the road base.
Rain or other moisture will moderately swell the clay fines and the cracks will close. If the clay material is highly expansive, then the amount of fines should be kept low to reduce the amount of cracking.
Prior to placement of any surface material, the Perma-Zyme treated soil should be lightly sprayed with a dilute solution of water & Perma-Zyme to assist in the bonding of the new surface material (i.e. Asphalt) to the road base. Moisture will close many of the cracks.
Reflective cracks should not migrate upward through the asphalt, unless the clay fines are in the upper range and site conditions see radical sub-surface ground moisture variations.
Proper drainage will reduce ground moisture and keep cracking to a minimum.

After compaction, what is the ratio of expansion? Will extreme weather affect the road (hot or cold)?
After compaction, the expansion-contraction ratio will be dependent upon the soil type (percentage of expansive clays) as well as the gradation range (distribution of particle sizes). Well-graded soil (ranging from -200 mesh to 1 inch) is ideal for road building. The -200 mesh fines should be approximately 20%. If the frost level extends below the level of the road some heaving may occur, however in the spring to road should settle back to its original elevation without severe damage. Proper road construction including shoulder drainage will minimize the effects of frost. Good engineering practices should be observed. Hot weather does not affect a road, other than dry dirt surfaces tend to be dusty under high wheel loading. Perma-Zyme treated surfaces will reduce the amount of dust.

When the road contains more than 20-30% clay, will the road surface become too slippery and lose traction?
