What is MOT Type 1?


MOT Type 1 is a crushed aggregate material commonly used as a sub base layer for various construction projects. It consists of crushed stone and is designed to provide a solid and stable foundation for surfaces such as roads, driveways, and paths. The "MOT" in its name stands for the Ministry of Transport, which originally set the specifications for this material in the UK.



MOT Type 1 is made from a blend of materials, including crushed stones, gravel, and fines (small particles of stone dust). These components work together to form a compact and durable base layer capable of supporting heavy loads. The material is graded to a maximum size of 40mm, ensuring it compacts well and forms a level surface.



MOT Type 1 sub base is a crucial material for any construction project. It serves as a solid foundation for roads, driveways, and patios. Understanding its properties and applications can enhance your projects success.

When embarking on any construction project, particularly those involving roads, driveways, or patios, understanding the materials you use is essential for success. One such critical material is the MOT Type 1 sub base.



Some key functions and benefits of a subbase include:

  • Load distribution: The subbase helps to distribute the weight and traffic loads from vehicles evenly across the underlying soil or subgrade. This helps prevent excessive settlement and deformation of the pavement.
  • Moisture control: A well-constructed subbase can provide drainage and prevent water from accumulating within the pavement layers, which can lead to damage and deterioration.
  • Strength and stability: By providing a stable and compacted layer, the subbase improves the overall strength and load-bearing capacity of the pavement system. It helps to minimize the risk of rutting, cracking, and other types of pavement distress.
  • Uniform support: The subbase helps to create a uniform and consistent support layer for the pavement, ensuring that the overlying layers are adequately supported and protected.


The type of material used for the subbase can vary depending on the specific project requirements and local conditions. Common materials used for subbase include crushed stone, gravel, recycled concrete, and stabilized soil. The thickness and composition of the subbase are determined by factors such as traffic volume, soil conditions, and climate.
