High Specification Aggregates

High Specification Aggregates (HSA) used for the construction of durable, skid resistant road surfaces are relatively rare and highly specialised aggregates which can only be obtained from a limited number of sources.

A & A is the sole Agent for Gritstone High Specification Aggregates from Gibson Bros Quarries Ltd. of Banbridge, Co. Down.

The aggregate is CE Marked and produced to BS EN 13043 "Aggregates for bituminous mixtures and surface treatments for roads, airfields and other trafficked areas".

The specific thresholds used to define HSA and the corresponding values of Gibson's aggregate are summarised in the download below.

Aggregate can be shipped in bulk to any suitable Port in the British Isles and sold on either CIF or FOB basis.

Our shipping agents are vastly experienced in handling bulk aggregates and can offer competitive shipping prices and terms. We can load vessels on a 24 hour SSHINC basis where required.
