Hi all, just after some tips on laying tarmac and compacting with a wacker, got some paths to do for my girlfriends uncle (on the cheap) how is best to tackle this?
Theres already base down, been down years, would this need a tack coat?

Tack coat required? Yes, otherwise the new surface course will fail to bond to the existing binder - it will move about and become a right mess.
Compacting with a plate? Not ideal but if you do you'll need one with a water system if you only have this for compaction.

Is it really worth you doing the job?
Can you get the areas ready and have a local gang into do it?
Buying tarmac ex-works as a punter is expensive........plus do you have the equipment and transport to fetch it?
I'd go for an ordinary 6mm 100/125pen limestone. Nothing fancy needed.
How far away are you from a tar plant?

The areas ready, just going to clean off with a good jet wash, tack coat and lay it only about 3tonne i think, been to have a look tonite, the guy himself is going to give me a lift as he works for balfour and has a bit of experience with tarmac, thanks for the pointers anyway.
Going to get a mate to bring it in his 7.5 tonne wagon and borrow a small pedestrian roller off him, should be orite i hope!
what does the 100/125pen bit mean?

pen refers to penetration grade bitumen.
the lower the number, the harder the grade. softer grades may be more workable, but won't be as tough as harder grades. most common grades are 40/60, 100/150 & 160/220 - generally 100/150 seems to be a good compromise.
