What Are Planings?

There are many different types of aggregates available, and in most cases the names they are given – such as sand, shingle, granite and gravel – mean that it’s fairly obvious what they are. You might also stand a pretty good chance of working out one or two practical uses for them all without too much prompting.

And then there are planings, or road planings to give them their full name. There’s nothing there to indicate what they could even be, let alone what you could use them for!

So in this article, we’re going to explore what planings are, what they are used for, and why they are such an environmentally friendly option for so many different construction projects.

What are road planings?

If you’ve had your road resurfaced by your local council recently, you might have briefly paused to wonder about what would happen to the old surface once it’s been removed to make way for its newer, smoother replacement.

Removing the surface involves the use of a cold milling machine, which reduces the asphalt down so that you end up with a granular material – and it’s this material that we’re talking about when we refer to road planings. And the great news is that, because very little goes to waste in the world of aggregates, those planings have many further uses once they’ve been taken away. 

They are made up principally of bitumen, a binding agent produced from petroleum, which is mixed with aggregates such as gravel and crushed rock, to form the asphalt road surface that is laid on top of the concrete sub-base.

What are road planings used for?

Once the planings have been removed from a road, they can be used for a number of new projects. These include, but are by no means limited to:

  • Footpaths
  • Car parks
  • Hardstanding
  • Farm tracks
  • Void fill
  • Sub-bases
  • And many more!


Are road planings eco-friendly?

Yes, road planings are considered to be an environmentally friendly source. Given that road planings are made up of 100% recycled materials, that means that any further usage is going to prevent the mining of other, potentially virgin, aggregate materials. 

Not only that, but such effective reuse and recycling also means a considerable reduction in the amount of waste that might otherwise be going into landfill. 

All in all, then, using road planings for your project is a great way of ensuring that you’re working in a responsible and eco-friendly way.
