compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a 10.0 mm BS test sieve. If required .This document describes a test method for determining the aggregate impact value (AIV) of aggregates, which provides a measure of their resistance to sudden shock or impact. The test involves compacting aggregate samples in .4. procedure. The test sample shall consist of aggregate the whole of which passes a 12.5 mm IS Sieve and is retained on a 10 mm IS Sieve. The aggregate comprising the test sample shall be dried in an oven for a period of four hours at a temperature of 100 to 110°C and cooled.The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent fines value described in BS 812-111 is applicable. A test specimen is compacted in a standardized manner into a steel cylinder fitted with a freely moving plunger.

limitations before any testing is performed. A. SCOPE This test method which is a modification of AASHTO Designation T 96, is used to determine the resistance of coarse aggregate to impact in a rotating cylinder containing metallic spheres. This test is known as the Los Angeles Rattler Test. B. APPARATUS 1. Los Angeles Machine. The Los AngelesAggregate impact value = W1 W2 × 100 Aggregates to be used for wearing course, the impact value shouldn’t exceed 30 percent. For Mould Falling Hammer Specimen Figure 8:3: Impact test setup bituminous macadam the maximum permissible value is 35 percent. For Water bound macadam base courses the maximum permissible value defined by IRC is 40 .
The average aggregate crushing value (ACV) and the aggregate impact value (AIV) obtained from the evaluations is 28.7% and 29.5% respectively and are within the acceptable standard limits. The specific gravity and water absorption gave average values of 2.60 and 0.22% respectively while the flakiness index obtained from the analysis is 26.7%.
