Mare's Tail Vs New Tarmac Driveway

Hi,

We're in much need of some advice before we proceed with an expensive decision!

My wife and I are in the process of having a new tarmac driveway installed, but the company doing the work have discovered (after excavating the old concrete one around 6 weeks ago -  it's a long story!) some Mare's Tail growing in the area where the new tarmac is supposed to be laid. It's not in abundance at this stage, with only a few shoots showing through.

The company's quote said they'd lay down MOT Type 1 hardcore with an 80mm layer of tarmac over the top.

My question - would over 3" of tarmac prevent Mare's Hare from bursting though the surface and ruining the driveway?

Many thanks in advance for your advice / replies!

    It didn't stop my mums.  My Dad had the front lawn tarmac-ed. It still comes through.  Hardcore then a membrane then tarmac might do it.
    You don't stop doing new things because you get old, you get old because you stop doing new things. <3
