5. [10 Marks] For your road project, determine the cumulative
total 18-kip Equivalent Single Axle Load Applications (W18)
expressed in millions for the design period. Follow the AASHTO 1993
Pavement Design Guide. Notes: • Use a design period of 20 years. •
Your ID-specific initial AADT0, Truck fraction and Traffic growth
rate are given in Table 2. • Use the Truck Factor (Tf) value that
you already found in the previous problem. • Use reasonable
estimation of other parameters - indicating the sources of
information.
