MOT Type 1

MOT Type 1, also known as MoT Type 1 or Ministry of Transport Type 1, is a specification for a crushed aggregate material used in road construction and other civil engineering projects.

It is widely used in the United Kingdom as a base or sub-base material for roads, driveways, pathways, and other applications where a strong, durable, and load-bearing surface is required.

Here Are Some Key Features of MOT Type 1

  • Composition: MOT Type 1 is made up of crushed rock and stone aggregates, including granite or limestone. The exact composition may vary depending on the source, but it generally consists of a mixture of coarse particles ranging in size from 40mm down to dust.
  • Strength and Durability: It is designed to provide a strong and stable foundation, capable of withstanding heavy loads and traffic. The compacted material forms a solid base that helps distribute the weight evenly and prevents settling or deformation.
  • Drainage: MOT Type 1 has good drainage properties, allowing water to pass through it easily. This helps prevent waterlogging and maintains the structural integrity of the road or surface.
  • Frost Resistance: It is also designed to resist frost damage, which is important in colder climates where freezing and thawing cycles can cause deformation and cracking
  • Compliance: MOT Type 1 meets the specifications set by the Department for Transport (formerly the Ministry of Transport) in the UK. These specifications ensure that the material meets the necessary standards for use in road construction and infrastructure projects.

MOT Type 1 is typically laid in layers and compacted to achieve the desired strength and stability. It is commonly used as a sub-base layer beneath asphalt or concrete surfaces. Additionally, it can be used as a base material for driveways, pathways, and other hard surfaces.

When using MOT Type 1, it is important to follow proper construction practices and guidelines to ensure the best results. Consulting with a local supplier or expert is recommended to determine the appropriate application and specifications for your specific project.
