Unadopted road saga - Is this spec ok? why no base course?

Setts and cobbles, tarmac, asphalt, resin systems, concrete whether it's plain, patterned or stencilled, gravels, etc.

Hi,

We have received a very reasonable quote for asphalt road. Its a no through unadopted road only 36 meters long but on steep incline. We asked for a light commercial spec. they have come back with spec of 30mm surface layer, 50mm binder and 200mm sub-base. there is no base course which i notice looking through this website is optional anyway. The existing surface is basically mud and stones - a road it has never been built. Is this good enough? Thanks

Clare ???

Yes it will be fine just be sure that they dig out enough to install the sub base to it full 200mm depth and that waste disposal is accounted for.

200 subase, 50 of binder(which is basecourse) and 30mm (compacted) of 10mm surface will be just fine. If there was to be anything heavier than 7500kgs over it I'd want a min of 60mm of base.

miss P see i said if you persevered youd get a reasonable quote after the original £80k joke, hope it goes well post some photos if you can or email them to one of us and we'll post them up.

Thanks everyone for getting back to me, much appreciated. So glad to hear that the spec is ok as we ran it passed the council and they said it was way too low even though it is for what is effectively a car park. The company we have chosen is very reputable and I trust your opinions over the council! Just need to get everyone to pay for it now. Will post pictures when its finally done.
Thanks
Clare

The spec isn't anywhere near good enough for a public highway but it will be miles better than the state of some of the council run and owned car parks!!

aye, some councils haven't updated their brown books and the specs i've seen are full of shocking errors.
i used to love using tarmac, but got fed up with getting my asphalt
