A roadway is being designed with a flexible pavement subject to the following loading and traffic. AADT is the current annual average daily traffic and growth is anticipated to be g = 3% per year. The AASHTO growth factor is ((1+g)"-1)/g. Determine the Design ESALs for design year 20 using a structural number (SN) of 4 and a Terminal Serviceability Index (pt) of 2.5. (10 pts.) AADT Axle Load (kips) L1 2 6,000 10 1,500 520 60 9. Determine the time of loading for truck speeds of 15, 25, 35, 45, and 70 mph and plot speed vs. time of loading, considering the radius of the tire contact area to be 6 in?
