In order to determine the relative proportion of different particle sizes available in an aggregate mix, sieve analysis or gradation test is to be performed. In this test, the sieves are arranged in descending order of their opening sizes and are stacked over each other as shown in Fig. 5. Fig. 5: Stack of Sieves.
The manual soil compaction hammers are lifted to their maximum height and allowed to fall freely onto the soil specimen for the required number of blows. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). The modified Proctor method uses a 10lb hammer with 18in (457mm) drop height for compaction.
