How to lay tarmac

A typical residential driveway would require a total of 75mm of Tarmac in two layers.....50mm of binder and 25mm of surface course. Make sure your stoning up (150mm min) s accurate, as any make up with Tarmac will be expensive!

ok cheers im doing the prep work my self and leave the tarmac to some one else ,whats the best hardcore to put down ive heard of type 1 mot,also can i just put the hardcore down then wacker plate it all should i do it in stages,couple of ton a time and wacker plate it like that .and do i need to hose it down as i do it thanks

100mm layers of type1 whacked, no need for water unless really dusty.

[danny1]

ok so if i put 100m of type 1 wack it down then do 50m of type 1 then wack that down is that the best way to do the base,Also part of the front already has a tarmac drive which has been down 15 years would i need to take it all up all can i just take the tarmac off it as well as the binder

Depends upon levels......you could if levels allow overlay the old tarmac but for a pukka job take it up and start afresh.

Yes bring your stone up gradually and trim it carefully to finished level

Correct ground preparation is the most important part of any drive and paving project. Without the proper preparation and materials it will simply sink. This is because the top layer of block, slab or tarmac will not be properly supported below.
