24-12-2015 · Sieve Analysis (ASTM C 136, AASHTO T-27): This test method evaluates the gradation of aggregate using a series of sieves. The results are then plotted on to a semi-log aggregate gradation chart. This chart shows the particle size distribution for any given aggregate and can then be better evaluated for its use in portland cement concrete and asphalt concrete. 2,7
