Grosey Posted August 3, 2016 Share Posted August 3, 2016 Hi, I've got a friend who owns a landfill/recycling plant and produces recycled aggregates. He can basically produce me any size hardcore I require. I I am looking to lay hardcore over the front of my site so it's a hand standing area and won't turn in to a quagmire when vehicles and deliveries begin. After construction this area will become a gravelled driveway, what would be the best size hardcore to lay? 40mm to dust or something larger? Thanks Link to comment Share on other sites More sharing options...
jack Posted August 3, 2016 Share Posted August 3, 2016 We used recycled crushed concrete for our 45m long driveway, which came in all sizes from fines to something approaching half brick size. It wore remarkably well for 18 months and is now a base for our gravel driveway. Do you need it to be permeable (eg, to meet SUDS requirements?) You should also put a geotextile membrane down to prevent migration of the new layer into the ground beneath. Link to comment Share on other sites More sharing options...
Crofter Posted August 4, 2016 Share Posted August 4, 2016 Use of a textile is not always necessary. As a rough rule of thumb, you want your largest particle size to be about half the depth to be laid. There's some excellent advice on all matters hardcore on Paving Expert Link to comment Share on other sites More sharing options...

Construction Channel Posted August 4, 2016 Share Posted August 4, 2016 but on the topic of hard core for heavy use drive ways. i would probably go for 6-8" of 4" and down then 2-4" of 40mm-dust on top of that, 1 Link to comment Share on other sites More sharing options...
Pete Posted August 4, 2016 Share Posted August 4, 2016 We used road planings and it has worked a treat. You do not get so much dust so it is really permeable and has compacted down with the traffic really well. We put ours on Terram membrane as the price of the road planings was £5.00 a ton!

joe90 Posted August 4, 2016 Share Posted August 4, 2016 Pete, that's good news for me, I have hardcore laid down and the local farmer who is taking all my clay away knows a bloke that transports road planings away and has arranged three 20 ton Lorry loads for me, glad to know it works well.

Grosey Posted August 12, 2016 Author Share Posted August 12, 2016 Just to close this issue had my first load delivered today, 4" down, got a nice levelled site entrance now which should pay dividends for all future deliveries. Next load coming tomorrow morning. 2 Link to comment Share on other sites More sharing options...
jack Posted August 15, 2016 Share Posted August 15, 2016 Looks like a good mix of sizes there. Should bed down nicely (and it will need to looking at that slope! ) Link to comment Share on other sites More sharing options...
