1. (Source: Potter) A coal-fired power plant is served by 25 trucks. When loaded, each truck consists of one single-axle of 14 kips (the front axle), two tandem axles of 32 kips each (the middle axles) and one single axle of 22 kips (back axle). Each truck makes 25 daily trips. The weights on the same axles when the truck is empty and leaving the power plant are 10 kips, 12 kips, and 8 kips, respectively. A twolane road...

Two routes connect an origin and destination with performance functions t1 = 5 + 3x1 and t2 = 7 + X2, with t's in minutes and x's in thousands of vehicles per hour. Total origin-destination demand is 7000 vehicles in the peak hour. Traffic is consisted of 6100 passenger cars (each with two 2-kip single axles), 800 buses (each with two 2-kip single axles) and 100 heavy trucks (each with one 12-kip single axle and two 34-kip tandem axles.) How...

The traffic on the design lane of a proposed four-lane rural Interstate highway consists of 40% trucks. Studies have shown that the truck factor can be taken as 0.45. Design a suitable flexible pavement using the 1993 AASHTO method if the ADTT during the first year of operation is 1200. PSIni-4.2 and PSIterminal-2.0. The growth rate is 5%, the design life is 20 years, the reliability level is 95%...
