MOT aggregates is an abbreviation of the Ministry of Transport aggregates. Most of these sub-base materials are usually available in granular form. Use of these materials is mostly seen in the civil engineering and construction industry. Some of the commonly used options are MOT Type 1 and Type 2. However, it is possible to observe differences in the grading, composition, and strength. Due to the wide range of benefits, MOT Type 1 in Derbyshire is mostly utilised for driveways, patios, roadways and garage bases. Still, it is better to understand the difference between the two to come to an informed decision.
Difference Between MOT Type 1 and Type 2
Size and Composition
MOT Type 1 is a hardcore combination with the graded stone mix between 0mm and 40mm. It is usually made of limestone, granite, gritstone, and basalt. Due to the range of particle sizes available, it may become easier to fill the gap. It may not be difficult to compact these aggregates.
In the case of the MOT Type 2, it is possible to notice graded material between 0mm and 20mm. Therefore, it may be a finer option in comparison to the MOT Type 1. It usually combines stones and particles. It may also seem less dense. Recycled aggregates, crushed concrete bricks and angular stones may be included within the material. It may be slit or clay instead of mere dust.
Key Features
Dust and crushed stone help create a supportive and strong base for the compaction. Therefore, it becomes possible to get a stable surface that can easily handle heavy loads. If the location is compacted, it may not shift from vibration. Frost thaws and heavy rains may not be able to make an effect on the surface. It may allow for a trustworthy sub-base.
On the other hand, MOT Type 2 comes with loose compaction, which makes it different from the former option. The smaller particles may be a reason behind its appearance. It usually has a lesser load-bearing capacity.
Uses
MOT Type 1 is more suited for heavy traffic, such as driveways, carparks, and patios. It can be easily used for residential as well as commercial locations.
MOT Type 2 is best for locations with light loading and proper drainage systems. Therefore, it can be utilised for footpaths, private driveways and walkways. For filling the potholes, experts may use them effectively.
Which is the Best Option For You?
Depending on the application, you must choose a sub-base aggregate. If you are looking for a compact base that can withstand a heavy load, experts recommend going with the MOT Type 1. If drainage is an important factor, rather than load-bearing capacity, MOT Type 2 may be a good choice.
