Problems with pressure washed tarmac

[demonjohn]

I have a driveway of 400 sq m. It is well laid but 10 years old.
I have had it cleaned with a pressure washer. It looks like new but the washer has fetched outsmall pieces of tarmac. Is there a product I can use to coat the surface to prevent soil etc settling in the gaps and causing problems. If so can you help with contractors to apply same?

Hello all,

I have a similar problem to the OP but with the added problem of two small pits/dents caused by the wheels of my trolly jack.

The garage driveway is about five years old but now has a zig zag line where the pressure washer removed a small amount of binding/tar.

This is the worst part;







Any good?

Thanks in advance,

Maybe you need something under your jack to spread the load, ie; piece of ply, metal plate.

Any good? No, not really but it's the best you can hope for really.

Ta for the replies,

Yup, have been using thickish ply to avoid this problem again.

So the B & Q stuff is worth a go ?

The other thought I had was to use older tarmac which has been discarded by builders down the road, could I use a heat gun to warm it up again and feed it in?

Not being a cheap skate, just thought it may blend in better with what's there already.

best to use fresh tarmac or any bagged cold mix repair if you want to do a patch. heat guns may work on fresh laid tarmac (for minor repairs) but to be fair there is a danger of burning the bitumen and killing all the sticky properties. as said before not many asphalts will withstand point loading forces so it's wise to spread the load.

i do know of a driveway contractor who used a burner under a wheel barrow of left over tarmac to 'liven it up' for his next job.

Thanks, is it best to cut out the hole making the edges square, it looks quite a thin top surface so maybe it will feather otherwise?

[Dave_L]

But it will always show as a patch repair..........

[Plant5]

Yup, I figures it would, also the jet wash marks will still be visible (not shown in pics)

The idea was then to go over the whole lot with something like this http://www.picscoat.com/

I ended up buying Wicks cold lay tarmac, is this solvent based? if so will it go off once the bags open, also what can I use as a solvent to clean tools ect..

Thanks,

[Pablo]

Yes it wil go off but you'l be dead before then it's not great stuff but does the job for small repairs etc. Tools won't get dirty but if they do use a rag with petrol or diesel.

i remember a contractor using cut-back tarmac (6mm medium graded) to surface a school playground and it became lively for the next 3 summers. he ordered cutback as it was handlay with poor access.

[Plant5]

Thanks for the replies,

I have noticed the Wicks stuff is only 6mm which looks a tad smaller than what's down already.

Builders down the road are laying the exact same grade on a new construction project, may have a word with them :;):
