Temporary road - weight capability

[Kingo333]

Hi everyone, I wonder if I could get some support.

I am currently building a new temporary road system and wondered if you anyone had any information that would help me understand what plate test results different cranes need, so either tonnes/m2 or UDL.

Any support would be appreciated as I want to complete a chart to make it easy for construction companies to see what temporary road system they can use for different projects. Thanks for any help you could offer.

I know the plate test results we had done which as an example for one of our options were 620kPa.

I am trying to find out what maximum vehicle weights my road could accept.

So is this a road system to transport vehicles including cranes or the actual crane mount itself.

For a road, normally you simply use max axle loads or wheel loads over a tyre square area to get ground bearing, plus whatever load spreading you calculate.

I would normally look at a max of 11 tonnes/axle over two large tyres or four smaller ones. You would typically be looking at > 500kPa. But this is surface contact and flexible paving is waht it says v-flexible.

this is quite an interesting read. Not the spacing of the axles is as important as the number and size of tyres. https://www.roadex.org/wp-content/uploads/2014/01/3.-Trucks-and-road-performance-P-Varin.pdf

But the requirement of the spreader plates under the crane is very different and you really need to be careful to avoid a sudden collapse or "soft foot".

Thanks @LittleInch for the response. I’ll have a read of the article appreciated.

Temporary road systems come in many shapes and sizes, but most realy on some level of load spreading so that you can lay then onto soft ground and avoid rutting or wheel tracks and keep vehicles moving.

what's different about yours compared to everything on the market already?
