Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

The following figure shows concrete pavement with the layer thickness and elastic modulus as indicated. Assume modulus of rupture of 650 psi, load transfer coefficient of 3.2, serviceability loss from 4.5 to 2.5, and drainage coefficient of 0.9.

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.
