MOT Type Sub Base: A Comprehensive Guide

MOT Type Sub Base is an essential component of many construction projects, particularly those involving roads, driveways, and other hard surfaces. This material provides a stable base upon which the final surface can be laid, ensuring durability and longevity of the finished product. In this article, we will explore what MOT Type Sub Base is, the different types available, and how it is commonly used in construction. 
 
What is MOT Type Sub Base? 
 
MOT Type Sub Base is a crushed aggregate material that meets the standards set out in the Ministry of Transport (MOT) specification for sub base materials. This specification was originally created for use in the construction of highways, but it has since been adopted for use in other applications such as driveways, car parks, and industrial yards. 
 
MOT Type Sub Base is a mixture of various sizes of crushed rock and stone, which are blended together to create a consistent and stable base layer. It is available in a range of grades, each of which is designed to suit different applications. 


 
Different Types of MOT Type Sub Base 
 
There are several different types of MOT Type Sub Base available, each of which is suitable for different applications. The most common types include: 
 
MOT Type 1: This is the most commonly used sub base material, and is suitable for most applications. It is made up of a mixture of rock and stone, and is designed to provide a stable base layer for roads, driveways, and other hard surfaces. MOT Type 1 is available as recycled and quarried aggregate. In most cases the recycled MOT Type 1 aggregate is cheaper, albeit being a by product of demolition recycled MOT Type 1 may contain fragments of wood, plastic, glass or metal.   
 
MOT Type 2: This is a coarser grade of sub base material, and is typically used in applications where a more substantial base layer is required. It is often used in the construction of heavy-duty industrial yards, or in areas where there is heavy foot traffic. 
 
MOT Type 3: This is a finer grade of sub base material, and is typically used in applications where a thinner base layer is required. It is often used in the construction of footpaths, cycle paths, and other light-duty applications. 
 
MOT Type 4: This is the coarsest grade of sub base material, and is typically used in applications where very heavy loads are expected, such as in the construction of airports and other large-scale projects. 

 


How is MOT Type Sub Base commonly used? 
 
MOT Type Sub Base is commonly used in a variety of construction applications. Some of the most common uses include: 
 
Road Construction: MOT Type Sub Base is an essential component of road construction, providing a stable base layer upon which the final road surface can be laid. It is used in both new road construction and in the resurfacing of existing roads. 
 
Driveways: MOT Type Sub Base is commonly used in the construction of driveways, providing a stable base layer upon which the final surface material can be laid. This helps to ensure that the driveway remains level and stable over time. 
 
Car Parks: MOT Type Sub Base is also commonly used in the construction of car parks, providing a stable base layer upon of which the final surface material can be laid. This helps to ensure that the car park remains level and stable, even when subjected to heavy traffic. 
 
Footpaths and Cycle Paths: MOT Type Sub Base is also commonly used in the construction of footpaths and cycle paths, providing a stable base layer upon which the final surface material can be laid. This helps to ensure that the footpath or cycle path remains level and stable, even when subjected to heavy foot traffic.
