Are there any members on here that are familiar with a type of polymer that's used to fuse rock or gravel road surfaces together?
There was a program on tv that showed a particular road in a remote part of Canada that is a lifeline to the communities. It's the only way in or out and doesn't hold up well to the freeze and thaw cycles. It had to be redone every year and was treacherous at times.
Don't recall all the finer details, but the road was packed and leveled and all the holes filled. A crushed rock was spread evenly and again packed. Then, water trucks with some type of polymer was introduced or mixed with the water in the tanks. This mixture was then sprayed onto the road surface. After it dried, the molecular structure of the polymer fused the rocks together. To demonstrate what the polymer does, a person with a sledgehammer deliberately swung at the road surface and it was as though the road was concrete. The sledgehammer just bounced off the road.
A year later the film crew returned and the road surface still looked new.
Anyone familiar with this polymer stuff? Sounds expensive.
That was the first and last time I've heard anything about it.
