Procedure of Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled. (i) Sieve the material through 12.5 mm and 10.0mm IS sieves. The aggregates passing through 12.5mm sieve and retained on 10.0mm sieve comprises the test material.Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. ANOVA was developed by the statistician Ronald Fisher.ANOVA is based on the law of total variance, where the observed variance in a particular variable is . Aggregate Impact Value (percent) = (W2 / W1) × 100; Take the mean of two observations, rounded to the nearest whole number, as the Aggregate Impact Value. Observations and Results.
