Repairing Tarmac Drive

coolagarry

I have a large tarmac drive ("20m x 5m) and it has seen better days... moss growing in places - surgace getting a little loose etc. Its been down for about 20ys and could do with a little tlc. Its perfectly sound and was obviously properly laid in the first place. I would like to spruce it up but certainly don't want to dig it up (In any case I couldn't afford it ).
Is it possible to clean it up and re-cover just the top layer to improve the appearance? Any advice would be appreciated

Thanks for that. I really need to cover the whole lot so it looks like a newly tarmacked drive but just putting the top on. It seems a shame to dig up a sound drive but it looks so rough. Could the cold tar be spread all over and form a top surface?

A surface dressing is applied to public highways where the foundation is structurally sound, some info here:

(take a look at the links on the left, especially "Micro asphalt and slurry surfacing")

I would suggest that you contact your local registered "drive" installer (not the guys who just happen to be in the area and wondered if you wanted your drive doing).He would be able to lay tarmac on top of the existing material, if the base coat is still quite firm. Otherwise any loose material should be removed prior to applying new.What he should be using is a tack-coat which is usually a water/bitumen emulsion which is sprayed or brushed on and provides additional addhesion between the old and the new layers.
