Soiltac, Perma-Zyme And Other Soil Stabilizers

I work for a local roads authority and we have been trialing the various soil stabilizers/dust control agents on our unsealed roads
I reckon I have tried just about most of them ranging from lignum based, salt based, polymers, PVA (Soiltac) with varying results and now looking at Enzyme based products
I'm just wondering what other people have tried and had success with, So far the Soiltac has been pick of the bunch as far as longevity goes, The enzymes look promising, The polymer and lignum/salt based performance has been poor to dismal
I'm looking for a product that will work well as a wearing course on unsealed roads, Links to some of the stuff we have tried below
I guess it's worth mentioning the soil types we have range from clay's to limestone's and bluestone, We are also in a pretty dry climate so the hydroscopic products just don't work here
I would love to hear of anyone else's experiences with these or other products

And the enzyme base we are about to trial

I would be very keen to hear how your trial goes.
We do a lot of contract road maintenance for a local authority, all unsealed.
Mostly, we do a hard cut, sometimes a rip, on the shoulders, wet it and form it up and roll.
End result is good, but the budget only allows it to be done every one and a half to two years, so it is looking pretty ordinary by then.
Always wondered if we could produce a longer lasting road with a stabilizer, or more importantly, if it is cost effective.

No worries Queenslander, I'll let you know once we trial the enzyme stuff
We are currently using the Soiltac on a limestone rubble which is proving fairly durable for dust control, we were just spraying it on top of the prepared surface at around 50 cents M2 and getting a year or more out of it but this year we are mixing it in with the material at around $2.20 M2 which should get us over five years, Soiltac is from the US so shipping is pricey
I had a look at another product today which is a bitumen emulsion based product but at $3-$4 a square meter is a bit pricey
The enzyme based stuff I have been quoted at $10 a square meter so that's a bit spendy too
Some of the prices I've been quoted for this stuff would get a chip/spray seal so we need to weigh up the pro's & cons
The ongoing quest for dust control continues

Man, those enzyme prices are super scary.
At $10/m2, one km at 5m wide would be $50000.
Definitely out of the question for the distances we are dealing with.
I'am still tempted to trial something a little cheaper.

On edit, I see you have already listed the Polycom website.
Did you investigate their product?

Yes I did mate and I can only say that they have great marketing
The polycom is probably good as a water saver or compaction agent but as a dust control or a wearing course the results were less than spectacular and I wouldn't use it again
I had the original developer of the product on site and he showed us how to mix it in at the right ratios etc and within a couple of weeks the roads were just as dusty, It did aid with compaction though and that was the selling point that the roads would be compacted better so therefore would last longer
The theory was good the results weren't

It did occur to me that that is one thing they all have in common, thanks for the heads up.
