Hello,very good and helpful forum,I hope someone can help me. I have a worn out and rutted crumbly tarmac drive,not laid too well and in some places it appears the sub base is plain sand/stone ballast. However it does seem quite solid without any movement. Could I set edging kerbs around this and lay a new sub base on top of this to lay block paving or should I dig up the old drive and start again??The land/border along the drive is raised and would not look out of place. Thanks for any views.

If the sub-base is, as you suspect, reasonably sound, you could excavate and remove the existing bitmac, then just regulate what's left with a sprinkling of DTp1 and then construct your new driveway as indicated on the main website.
Don't lay over the old bitmac - it degrades over time and will probably cause more trouble that it's worth. If you have, say 75mm of bitmac, then skimming that off, and then re-grading the sub-base and regulating with 25mm of DTp1, means your finished level need be only 50mm or so higher than what you have at the moment.
