Notes:
* Based on the California Bearing Ratio (CBR) of the underlying soil.  For soils with a CBR of three through six, ten inches is required; with a CBR of seven through ten, eight inches is required; with a CBR over ten, six inches is required.  If the CBR is below three, then the soils are unacceptable for road construction.
** Flexible Pavement shall be Asphalt Concrete Type “B,” MV as set out in the state Department of Transportation Specifications, latest edition.
