It's that or constantly repair it. Forklifts destroy paving, high point load, wheels turning on the spot etc

C30 as a minimum for industrial floor repairs as such. 48hrs then, but the longer the better.
This is where bitmac has a major win over concrete - trafficable after an overnight period.

Bitmac - the proper name for "Tarmac"
"Black shit" to many.

cover the area with a 5mm steel plate for a week to add surface protection, just make sure the driver so carefully over it as well. i know this is impossible with forklift drivers, we often epoxy the sheet down or screw it then fill the holes

Gi's idea is more or less what we used to do.
We had a contract to maintain and repair the haul roads and transfer areas on a series of landfill sites. We'd get possession of the site on Saturday lunchtime, excavate, prep and pour a C40 mix late afternoon, cover it with 2 layers of hessian and 1 of visqueen overnight (to keep the humidity up), and then strike on Sunday, strip the visqueen, but leave the hessian in place, cover it with either two layers of 18mm ply or 1@ 18mm ply and 1 steel roadplate laid stretcher bond to spread the load.
They'd be running bin lorries and 8-wheelers on it from 6am on the Monday, and then we'd be back the following weekend to strip the covering, if it hadn't been moved half-a-mile up the site by the constant flow of wagons.
We did this for about 5 yerars and never had a problem. It wasn't pretty work, and we did get corner cracks on occasion, but it was an industrial area so as long as it was functional and didn't cause the FLTs to tipple over, it was deemed acceptable.

We have products such as Ronafix, RonaScreed and others that speed the rate of strength gain.
Give us a call and we'll guide you through the options.
Temperature will influence strength gain too - colder = slower.
