The Brew Cabin

I am talking up my old tarmac drive and replacing it with blocks, I'm also widening it, Is the old tarmac any use to use as a base in the part that i'm widening. It just a thought so i dont have to get it skipped away, I'm guesing the base under the old tarmac part is going to be sound,
Cheers.
Ace site by the way

Just read this again. I wish I could spell. I'm not talking to my old drive at all, i'm taking it up.

You can use the EDIT facility if you spot any errors in a post of yours, but I knew what you meant. :)

Anyway, using old bitmac as a sub-base. Well, it's less than ideal, but it's better than nowt. I'd break it up as small as possible and then spread it out over the subgrade as a 'blinding', and then top it off with decent sub-base material. I'd be concerned if it was used to form the full-depth sub-base in one part of the driveway, with 'proper' sub-base material used elsewher, but, by spreading it out and combining it with 'decent' stuff, it should be ok for a residential driveway.

Thanks for the advice Tony. when i first posted the Q i had not looked at the site. What a great site.
