The Benefits To Open Graded Tarmac
So what are The Benefits To Open Graded Tarmac
Open-graded tarmac is a type of road surface that allows water to drain through it. This makes it ideal for areas that are prone to flooding or where there is a lot of rainfall. It is also less likely to puddle than other types of road surfaces. Open-graded tarmac is made up of a layer of aggregate (gravel) and a binder (such as bitumen).
The binder binds the aggregate together and the voids between the aggregate allow water to drain through. Open-graded tarmac is typically used on roads with a high volume of traffic, such as motorways. It is also often used on airport runways as it can withstand heavy aircraft landings.
Open-graded tarmac is not suitable for areas that are subject to freezing temperatures as the water in the voids can freeze and expand, causing the surface to crack. If you live in an area that experiences freezing temperatures, you should use a different type of road surface.
Advantages of open-graded tarmac:
-Allows water to drain through, making it ideal for areas that are prone to flooding
