Long term performance of gravel base course layers in ...

2018-12-1  In general, the base layer aggregate composed of gravel exhibited low soaked CBR values compared with typical crushed stone layer materials. The crushed stone particles with angular shape and rough surface texture result in better interlocking and resistance to penetration compared with natural gravel particles with round/semi round particles.

Sustainable Drainage System (SuDS) Aggregate -

2-6mm SuDS Aggregate. Our 2 – 6mm is an ideal top layer of any SuDS solutions. Typically, a 50mm top bedding layer of 2 – 6 mm SuDS is placed on larger 250mm course of 4 – 20mm SuDS aggregate prior to laying permeable block paving. This combination will allow excess water to slowly drain into the underlying ground and water systems.
