Question- At an industrial area an access road to an industrial facility is paved with a 3 Sand-mix asphaltic concrete wearing layer, a 5 Hot-mix asphaltic concrete base layer, a crushed stone subbase layer and has a structural number of 4. Assume that the drainage coefficient for the base layer is 1 and the drainage coefficient for the subbase layer is 0.94. The access road is designed for a maximum traffic load of 9x106 ESAL for 25-years design period. Find the thickness of its subbase layer of crushed stones used in this pavement.

Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.
