MOT Type 1

MOT Type 1

Primary

Also known as GSB TYPE 1 or MOT TYPE 1 - this is a granular material with a maximum permitted top size of 63mm, graded down to dust.

Description

Type 1 must be of a crushed nature to provide a stable sub-base for road surfaces and pathways. The mixture of solids and fines ensures minimal voids in the sub-base material when compacted, giving a strong load bearing layer with a suitably flat surface. Both primary and recycled materials can be used to make up a MOT standard sub-base.
