What is 6N Aggregate Material?

Class 6N aggregate material is a selected, well graded granular fill material that is typically used as a fill to structures. The grading requirements for this aggregate material are defined in Series 600 Earthwork of the Specification for Highway Works.


What materials can be used to produce Class 6N?

It can be produced using quarried or recycled materials.

This includes materials such as natural gravel, natural sand, crushed gravel, crushed rock, crushed concrete, slag or well burnt colliery spoil, such as quarried limestone or recycled crushed material from demolition and construction waste.


What are the specifications?

If the material is to be used within the construction of highways then it must meet the specification set out in the Series 600 Earthworks of the Specification for Highway Work, generally 0/50mm.

Compliance with these specifications ensure the durability, safety and reliability of highways although we also supply this 6N material to rail projects for backfill requirements. Our Class 6N aggregate is available both loose and bulk bags.
