2. A sieve analysis was conducted on an aggregate with a nominal maximum aggregate size of 20 mm. The following data was obtained: Sieve size (mm) Mass retained (g) 37.5 0 26.5 80 19.0 120 9.5 800 4.75 1450 2.36 130 Pan 80 a) Find the percentage of passing on each sieve and plot the particle size distribution. b) Show the Australian Standard (AS2758) upper and lower limits for this aggregate type on the same plot. As per this standard, is the aggregate well-graded or poorly graded? c) What should we do if the aggregate is poorly graded?
