I have an area the size of a dustbin lid approximately on my tarmac drive that has been damaged by a skip lorrys tyre!..the drive is only 18 mnths old and i would like to repair the area and match it in to the existing area as closely as possible, i was thinking of citting the offending area out with a diamond bladed cutter and re compacting the sub base which is also pressed and then replacing the cut out piece and heating it up with a roof burner and tamping back in?? is there any magic tricks here Tony??
Your proposed repair will work up unto the point where you replace the bitmac then mess about with a blow torch....that's when it will fail.
It doesn't matter how hard you try, the patch will NEVER match the existing, not even if you were able to source the exact same material from the same batch plant and lay it at the same tiume of year as the original material. Even at 18 months old, the original will have weathered and you just can't replicate that effect.
So, there's two problems - how do you replace the damaged mac, and how do you make it look 'invisible'?
For the repair, you could use one of the repair macadams, which are doped to buggery and back with cut-back to keep them workable for months on end. Alternatively, you can keep your eyes peeled for someone working locally with bitmac. They might be doing a local driveway, or it might be the council patching a footpath, but the point is they will have fresh macadam that won't be anywhere near as heavily doped as a repair mac and so will harden this side of Christmas. For the same price of a bag of repair mac (about a fiver) they'll let you have a couple of bucketfuls of the fresh stuff.
So: you've got the damaged area cut out and patched, now how do you make it seem invisible? The easiest way is to use one of the Bitmac Cover-Up products. These are basically special paints for tarmac and the idea is that they turn tired, dull, grey bitmac driveways into fresh, pristine jet black driveways with just a couple of hours work.
The existing bitmac has to be power-washed to get rid of any crud and detritus in the pores of the surface, and then, when dry, it's simply a matter of applying a couple of coats of the jollop to the entire driveway. Some of the products reckon one coat is sufficient, but they're lying - I've never yet seen a single coat have the desired effect. Use a roller, preferably a lambswool roller, to get even coverage and to ensure the voids are properly filled. The stuff takes a couple of hours to dry, but you can drive on it as soon as the waiting time is over.
And the finished effect is of one, homogenous-looking driveway. If you really look for it, you'll still be able to spot the patch, but it won't be as 'in yer face' as it was before using the Cover Up.
You can get the Cover-Up paints from Watco, from SupaMix and from B&Q Sheds, where it's sold as Thomson's DriveSeal. They're usually available in black and "bugundy" (posh for cherry red), but stick with the original colour as using these products to change the colour is never 100% successful.

i do not do tarmac that well i mainly do block paving but would this work?? if u remove the sunken part as a whole piece with a cutter lets say 2x2 ft square and lift it out then use some roadstone underneath to compensate for the sunk area then put back the 2x2 section u cut out back onto the new raodstone (should fit perfect bck in the square) then use the torch to reheat the square piece of tarmac and tamp it back down, this would mean the tarmac is not new and should blend in with the old as it was the old u cut out, now i do not know if this is possible only an idea.

Gardner Asphalt manufactures a complete line of bitmac repair products in the US, and are in the process of expanding our distribution in the UK. We manufacture two products that would be particularly well-suited to this case -- both a fine-textured drive patch for minor scuffs, and a heavy-textured Pothole Patch for the larger holes, as well as an asphalt emulsion to coat the entire drive that will bond to the surface, rather than just cover up an unsightly patch.
At this time, we expect to have wide distribution in the UK in the late autumn , but I can offer little help at this time.
Please keep visiting the Forum -- I'll post a notice as soon as it is regularly available.
