There's been reports of potholes all over the country and loads of complaints about them but no explanations of the cause for them?
Looking at them round here, it seems that the road surface that's failing is showing 1/ a lack of adhesion of the surface layer to what's underneath and 2/ the surface layer seems very "thin" and is comprised of coarse Tarmac.
Where potholes have been filled in with coarse Tarmac, it's only a few months before it's all broken out again but in places where they've been repaired with finer Tarmac, they're still OK after a year.
In "times of old".... roads were surfaced with hot Tar and chippings were spread and rolled on it. They don't seem to do that now?
I remember watching the first Tarmac being laid on the roads in to "our" village and that was fine Tarmac about two inches thick. It lasted many years. I don't recall any of it breaking up.
So, any Tarmac experts on here to give us a little run-down on current practice?
It's life Jim, but not as WE know it.
Live long and prosper.
