The specifications require that:
a) Yd must be at least 0.95 ya(max).
b) Moisture content w should be within +1.5% of wopt.
1) Draw (on graph paper) the compaction curve and ZAV curve. (Gs = 2.72).
2) Show for each location either it is accepted or not according to the specifications required and give
reason why?
