Aggregates Impact Test (AIV) Introduction: 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. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from
The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2.

Sep 12, 2015· The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn’t exceed 30 percent.

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report
1/(2n.). Table 1 lists values of the ratio of mean deviation to standard deviation for various values of "n" according to this criterion. In applying Chauvenet's criterion to consider the elimination of suspect data points, one first calculates the mean value and standard deviation using all of the collected data points.
