Problem:
The daily traffic in one lane of a highway with flexible pavement (SN=3 and TSI = 2.5) is estimated to be:
- 5,000 single axles at 10,000 lb each (equivalency factor - 0.118)
- 400 single axles at 24,000 lb each (equivalency factor -3.09)
- 100 tandem axles at 50,000 lb each (equivalency factor - 5.03)
The design life is 20 years, and the growth rate is 1%.
Required:
Question: Determine the total equivalent single axle loads (ESALs) over the design life.
Note: Please explain comprehensively and give step by step solution.
