Using the AASHTO procedure, determine the thickness required for a base and a surface layer, over a subgrade. The structural number required for the pavement is 4.5. The available materials are a granular base with a layer coefficient of 0.13 and an HMA surface with a layer coefficient of 0.40. The drainage coefficient (m2) of the base course can be considered to be 0.9.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
