APPENDIX B: MINIMUM DESIGN FOR STREET PAVEMENT

   (A)   Table I:  Minimum Design Characteristics of Street and Alley Pavements

Pavement	Pavement Class	Primary and Secondary	Local	Subdivision
Flexible**	Surface, No. 11	1 inch	1 inch	1 inch
Flexible**	Binder, No. 8 or 9	2 inches	2 inches	2 inches
Flexible**	Bass, No. 5	3 inches	3 inches	3 inches
Subbase	Compacted Aggregate	10 inches	6 through 10 inches*	6 through 10 inches*
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.

   (B)   Table II:  Minimum Design Characteristics of Street Pavements***

Pavement	Pavement Class	Commercial, Industrial Streets
Flexible**	Surface, No. 11	1 inch
Flexible**	Binder, No. 8 or 9	2 inches
Flexible**	Bass, No. 5	3 inches
Subbase	Compacted Aggregate	12 inches*
Notes:
* Based on the California Bearing Ratio (CBR) of the underlying soil.  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.
*** Developer shall submit an AASHTO pavement design showing the calculated pavement section required.  If analysis shows that less than the minimum section is required, the minimum section shall be installed.
