Determine the thickness of the pavement if the pavement is subjected to medium traffic and the CBR value is obtained as 7%.

Determine the thickness of the pavement if the pavement is subjected to medium traffic and the CBR value is obtained as 7%. Correct Answer 31 cm

The data given in the question is traffic condition and CBR value. The California State of Highways design chart is to be used. A sample of the same graph is given below. In the graph, curve A represents 3175 kg wheel load or light traffic, curve B represents 4082 kg wheel load or medium traffic and curve C represents 5443 kg wheel load or heavy traffic. The value corresponding to medium traffic and 7% CBR can be obtained from the chart as 31 cm.
