I need to make a cement roadway which can take the weight of a 40tonne wagon. I have 2 sizes I am looking at:

10m long, 4m Wide and 200mm deep,

20m Long, 4m wide and 200mm deep.

I have been advised I can used cement with fibre in it to make it stronger, but I was also going to uses that metal grid.

I have no idea if the cement is thick enough (it will be on a hardcore base) or what the metal grid stuff does/what thickness to have and where should it be positioned. Can anyone advise? Also does it need to be made in sections, if so what do you put between each section and how long can each section be?

This is for a wash down pad out of a temporary quarry.

Did try that and they were useless saying it was not up to them to advise.

Sounds like you need to talk to a decent ground working company that will do the whole job for you.

Personally I would look for a raised metal "cattle grid" type thing with a pit underneath as if its to wash down dirty trucks where is all the dirt going to go???

Your spec is nearly right. You need 4 metre bays divided by expansion joints. You need to put at least 10mm re inforcing grid sheets in the middle of the laid concrete.
Do yourself a favour and use experts to do the projected work.
Its not hard for someone like me.
But are you up to to job ?

It's not a 'Cement roadway' it's a Concrete roadway.

Get the pro's in and take their advice.

Also mention to them how Temp this is to be.

Just to give you a hint, the second of these will need 16 cubic metres of concrete mixed and laid, never mind the excavations and the subbase. Not normally a DIY job.

We've just done something similar, about 330m2. Very basically, to form concrete hardstandings, you need to do the following:

Excavate to required depth.
Lay Type 1 approx 350mm deep in two layers, each compacted.
Build shutters or use road formers to pour into.
Lay A393 mesh
Insert dowel bars between the joint on the big one. Small one might not need an expansion.
Place crack inducers underneath dowels.
Pour either a C50 or a PAV2 mix concrete (these will negate the need for fibres and resist frost) approx 220mm deep.
Brush finish (or tamped if using PAV2)

Ours was designed by a structural engineer, and to be honest is a bit overkill, but it will easily take a 40ton wagon, and does (plus some additional plant that's on it)

As a rough guide, paying someone else to do it, it should cost about £100 - £120/m2 (that's with spoil off site, but you've got a quarry so could save there) plus VAT of course.

Unless you've done it before, I would recommend you get two or three guys in to quote, it sounds easy but it's easier to screw it up.

Thanks very much for the figures.

I have diggers on site, and we have just put in a temp roadway using MOT type 1 and Tarmac planning. I am trying to avoid using expensive architects and contractors, how hard can it be?!!

I have a team of guys who can build what I need and they have built small concrete pads before.

I did look at the cattle grid option but they are very expensive as I would need 4 decent size ones, also the pit would need cleaning out which would be a PITA. This would also need a concrete foundation.

My idea is to have 2 jet wash machines either side of the pad to clean the wheels off the trucks as they come out and the pad is washed down at the end of every day. The muck and water will go into ditches which can be re-dug as required..

At £20,000 I need a cheaper solution. I have tried to find a used one but no luck.

Why not use asphalt paving on MOT Type 1 ? Surely less cost ?

The stuff others are talking about is PQ concrete as used on airport aprons. The only advantage of PQ concrete is that it is not a Newtonian fluid and hence stationary loads will not indent the surface.

ETA depth of construction depends on the CBR (California Bearing Ratio) of the subsoil

Why not hire a wheel wash if it is only temporary.

Tarmac is too expensive and not ideal for the job.

It is a 2 year operation, so hiring a wheelwash will cost as much as buying one.

I am not quarrying (just said it for ease of explanation!) It is an inert waste importation scheme (i.e clay, stone, soil) with about 40 deliveries per day.
