1. Plot graphs of binder content versus stability, flow, %V.T.M, %V.M.A., %V.F.B. and unit
weight.
2. From these graphs determine the optimum binder content for assumed values of (5%
V.T.M.) and (75% V.F.B.).
3. Check if that optimum binder content will meet the Iraq design specification (I.D.S.)?
4. State whether the mix requires redesigning or it can be used in the pavement?
