The AADTT of a 2-way (2-lane each way) highway is 10,000. The directional distribution may vary between 45 and 55% depending on season. The lane distribution may vary between 60 and 75%. The driving lane always carries more loads compared to the passing lane. The growth factor for the pavement is 3.5%. Based on the above information, calculate the design AADTT for the driving lane if the pavement service life is 20 years.
