A road with estimated 15 million ESAL for both directions after 20 years will be constructed on a subgrade. The CBR of the subgrade was obtained at 24% with standard deviation of 5% (85% probability). Determine the subgrade class and combined thickness of the wearing and binder courses with stabilized base using ATJ5/85 (2013).
