Base and road base FAQs
Everything you need to know about bases and road bases.
DGB20 is a well-graded course base with a particle range from 26.5mm to a minute dust. DGS40 is a dense graded stone asphalt mix with a nominal maximum aggregate size (NMAS) of 40mm.
RMS specifications are specifications set by Roads and Maritime Services (RMS), which is the New South Wales (NSW) government agency responsible for building and maintaining road infrastructure in NSW, Australia. They cover many aspects related to road construction, including materials, design, construction methods, and maintenance.
A road subbase is the layer of material placed directly on the subgrade to provide a stable foundation, while the road base is the layer placed on top of the subbase and below the surface pavement to further stabilise the road and provide a smooth surface.
Road base materials are typically stronger and more durable, such as crushed stone, asphalt, or concrete. Subbase materials include crushed stone or gravel.
Stabilised road base is a type of road base that has been treated or mixed with additives to improve its performance and durability. These additives can include cement, lime, fly ash or bitumen emulsion, which are combined with the base material (such as crushed stone or gravel) to enhance its strength, stability and resistance to weathering and traffic loads.
Crushed rock provides essential support and stability for construction projects and is a key component in building foundations, road bases and concrete production. It’s ideal for drainage systems, preventing waterlogging and erosion. Additionally, it plays a crucial role in soil conditioning and erosion control in agricultural applications.
Spalls are broken fragments of rock concrete or other materials. They can be used decoratively in landscaping. They’re a cost-effective alternative for certain projects, such as fill material or in drainage systems. Additionally, spalls matching the original material can be used for repairs and restoring damaged surfaces.
Scalps are small pieces of stone, often leftover material from construction or demolition projects. Capping material includes aggregate, soil and concrete. A layer is placed over a surface for protection, stability, or containment. Fill material can be natural, such as soil, sand, gravel, or rock, or recycled, like concrete or asphalt. It’s used to raise the elevation of an area or to create a level surface.
Our materials are sourced from our local quarry suppliers in the NSW region.
