Contact usMost of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3). Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO).

Contact usAggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve).
