Question: The current year axle load data for single axle with dual wheel on either side obtained on a two - lane two - way local

The current year axle load data for single axle with dual wheel on either side obtained on a two-
lane two-way local roadway is provided in the following table. It will be upgraded to four-lane
undivided roadway in next three years. If the design life of the roadway is 15 years and annual
traffic growth rate is 5% then find the horizontal tensile strain at the bottom of bituminous
layer and vertical compressive strain on subgrade. Assume resilient modulus of surface course
as 3000MPa.
