Aggregate abrasion value (AAV) – This test sorts out aggregates which might be strong but are not resistant to the abrasive action of vehicle tyres if used in the surface course of roads,, though suitable in every other respect, they wearout too quickly in use.
According to the recommended values as specified by Indian Road Congress, higher the aggregate impact value, lower is its impact strength. The aggregate with less than 20% of the aggregate impact value is exceptionally strong. So the natural aggregate is .
If {A(B+C)}>1 mm is weighed to the nearest 0. 3. The test sample is subjected to 15 blows of the hammer dropping 381 mm. (2) PROCEDURE . the result shall be discarded and a fresh test made. The crushed aggregate is sieved over a 2. The aggregate impact value (AIV) is AIV = B × 100 (%) A .
Aggregate is a granular material obtained by processing natural materials. BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as consists of particles of a rock, of a controlled particle size distribution, used in the construction of a building or civil engineering structure.
