We have recently done the corner of our yard in road planings. Ideally we would have used concrete but we didnt have the budget for it.
I've seen road planings used on other sites before and they seem to bond well and go off very hard. The planings we have used are 40mm to dust. We have rolled them in with a vibrating roller (about 2 1/2 tonner). It hasnt gone of as hard as we expected and I'm pretty certain that our forklifts are going to make a right mess of it.
Is it simply a case of getting a bigger roller or have we jsut used the wrong material for the job?
Also I was wondering if there was any machines on the market that could apply heat to the surface prior to rolling?
Cheers
Steve

like any loose material,if the vehicles are turning on it,it will chew it up. tar planings are great on a straight road,with no turning traffic. laid in hot weather, it will set like tar after vehicles have been running over it for a few weeks.
your best bet is to keep re-grading it over the winter and it might be better by the end of next summer.

Not sure about anything to apply heat.
Some say to put a small amount of diesel on it then roll, ive tried this on an old access road and it went pretty hard but then tried it on another job and it did fcuk all.
Don't be tempted to tarmac over it as it WILL sink.
Mite have been best to put some of your crushed gear in then 50-75mm of base or 10mm.

the council in luton had the bright idea a few years back of reheating old tarmac and respreading it and relaying it
(i know the poor gang involved)
anyway they soon figured it was costing more in butane than the cost of new tarmac

Tarmac planeings will go hard over time,i have done loads off jobs using them, with no problems at all,the top 1 inch will we lose for a time but will harden up with sun and traffic,very widely used in this area for roads and sub base to foot paths MSH

We put down 200mm of our crushed stone and rolled it, then we put 75-100mm of planings on top. I told my business partner it would definately work, so I'm desperate to avoid egg on my face :p

Forklifts and planings just don't mix. Not what you wanted to hear but its reality I'm afraid.

Ive seen the a farmer using diesel, went rockhard...even though it shouldnt as diesel degrades tar....how that works i dunno like!

I made same mistake last year steve, embarrassed when forks got on it, sunk a little then span. Lot of weight on small area. Will improve in a few months

not to state the obvious but you start spreading diesel you contaminate your land and your land lord isnt going to be happy not to mention the environment agency, all diesel tanks must bonded to prevent spillage....ergo spreading it isnt a great idea,
what are 99.9% of warehouses and forklift yards made out of.... brushed or power floated concrete the only way to go with forklifts

Not only would diesel posion the land and dissolve the planings, it would contaminate the tyres on the FLTs and spread everywhere, causing more skidding and stinking-up the place.
Planings or 'asphalt arisings' as we are now supposed to refer to them, have their uses, but hardstanding in a yard is not one of them. They will settle down with time, as long as they are well-drained, but for me, they've always been more trouble than they are worth.

there is a reason why they are 5 quid a tonne
thing is you dont know how old they are
in older roads the essential oils evaporate away leaving just a bit of bitumen and some limestone

Here i pay £16+ for MOT.
If i want planings (very rare i do) its a tenner for as much as i dare put on the wagon.
