Road Base Suppliers

Road base is made up of different aggregate layers as an essential foundation for roads, driveways and asphalt installation. Generally, road base is composed of various materials. Road base is available in different aggregate types and you can choose between these types depending on the project you are planning to work on.

For example, driveways typically use a gravel base as it tends to be relatively cheaper and provides a surface that suits the client’s aesthetic preferences. There are several considerations needed before you create your own driveway or look for road base for sale, especially if you want a long lasting and low maintenance driveway.

With this in mind, professional advice from road base suppliers is the key to identifying which type of aggregate is best for your road base layers. You need to consider the subgrade material that is present in the road base, sub-base, base and surfacing material.

A road base is composed of different layers to promote strength and stability. These layers are composed of different aggregates that help stabilise your road base project. The most common and popular material used is gravel, especially when it comes to building driveways. However, since there are multiple options to choose from, customers may have difficulty identifying which type of aggregate is appropriate for their project. Below is a description of three different road base layers:

Sub-Base Sub-base is the bottom layer of road base and is commonly composed of crushed stone that sits on top of the subgrade. It can also be a clean, low-plasticity fill material.

Base The base layer is also composed of crushed stones but unlike the sub-base, the stones are slightly smaller. This is to reduce gaps and spaces to help hold the layer in place.

Surfacing Material Surfacing material is the final layer of gravel that is poured on top of the base layer. This is usually where most customers focus as it allows them to pick the type of stone that will be used to give their driveways an aesthetically pleasing look.

If you are planning to buy road base, the average price ranges from $300 to $60,000. Road base prices vary depending on the project size, type of aggregate being used and amount of aggregate needed. The cost to install a road base is approximately $1.25 and $1.80 per square foot.
