Type of test The objectives of tests on road construction materials

Aggregate Crushing Value Test (BS 812:Part 110:1990)
• To determine the percentage aggregate crushed by applying compressive load

• Standard size of aggregate is normally used i.e passing 14 mm and retained on 10 mm
sieve size. Place about 3000 gm of aggregate in the mould in three layers and compact
with rod 25 times for each layer. Use compression machine to compress the aggregate
for 10 minutes with gradually applying load from 0 to 400 kN. Then, sieve out the
aggregate using 2.36 mm sieve size and determine the weight passing and calculate the
ACV

ACV = Weight pass sieve 2.36 mm x 100
