What are Aggregates?

To get the strongest pavement structure, larger aggregates are used for the base, with successively smaller dating sites reviews aggregates used for upper layers in the pavement. The hardest and most angular are used for the surface. Fines. Fines are the smallest sized aggregates, and they may be rounded or crushed angular particles.
