It is carried out by filling a steel test mold with a sample of aggregate 10 14 mm and then the impact load applied is by dropping hammer at a height of 380 mm. The Aggregate Impact Value AIV is the percentage of fines passing 2.36 mm BS test sieve after 15 blows 9. Table 6 Test result of aggregate impact value

Determine of Aggregate Impact Value Test BS 812. Experiment Name Determine of Aggregate Impact Value Test BS 812 Purpose of the test The Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop under specified test condition.
201442Specifications is 5.0 percent and applies to aggregate classes AP AS A B and C only. Abrasion Resistance Abrasion resistance applies only to coarse aggregates. Aggregates vary in their resistance to fracturing under impact toughness and breaking down into smaller pieces from abrasive action hardness.

Of strength could be due to PKS having lower strength when compared to normal aggregate. This is reflected from the impact value for normal aggregate which is double that of PKS see Table 1. Another factor that may cause the decrease could be attributed to the highly irregular shapes of the

Ii the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve to the nearest 0.1 percent. The results of the sieve analysis may be recorded graphically on a semilog graph with particle sie as abscissa log scale and the percentage smaller than the specified diameter as ordinate.
2 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under

Aggregate impact and 1. 10 Aggregate Crushing Value TestINTRODUCTION The principal mechanical properties reired in road stones are Q satisfactory resistance to crushingunder the roller during construction and jjI adequate resistance to surface abrasion under traffic.
Step11 Sieve the crushed aggregate through 2.36 mm IS sieve and weigh the fraction passing through it to an accuracy of 0.1 gram. This fraction is a measure of loss of material due to crushing. The mean value of two samples rounded to nearest whole number is taken as the aggregate crushing value. Observation and Calculation
