The CBR value of the soil is found out to be 6% and the traffic is 350 commercial vehicles per day. Find the pavement thickness using design charts provided by IRC.

The CBR value of the soil is found out to be 6% and the traffic is 350 commercial vehicles per day. Find the pavement thickness using design charts provided by IRC. Correct Answer 35 cm

A sample of the design chart for computing the thickness of pavement using CBR method by IRC is shown below. The curve D is to be considered as the commercial vehicles per day is 350 which lies between 150 and 450. The thickness corresponding to 6% CBR and curve D is obtained as 35 cm.
