   (a)   The following pavement standards for the various classes of streets are hereby adopted by the City:

 

CLASS OF STREET	RIGID PAVEMENT	FLEXIBLE PAVEMENT
Local or Minor	6" - Item 452	3" Item 404/403 on 10" Item 304*
Collector	7" - Item 452	3-1/2" Item 404/403 on 12" Item 304*

Item 301 Bituminous Aggregate Base

* For total asphalt pavements, the substitution of 1-inch of Item 301 for each 2 inches of Item 304 will be allowed.

   The required pavement sections shall be constructed on a compacted subgrade that has been rolled until it is compacted to at least ninety-five percent of the subgrade material's maximum density at optimum water content based on AASHO Designation T-180-57 Test Methods.

   The required pavement sections, together with diligent control in the field of subgrade compaction, trench backfilling materials and procedures, and pavement construction are designed to provide the City with relatively low maintenance cost street pavements.
(Adopting Ordinance)

   (b)   For the determination of compaction and density of the pavement, the City may take core samples of the pavement. Holes in pavement left by core samples shall be replaced by the developer at no extra compensation. If core tests are positive, the cost shall be paid by the City, and if negative, the cost shall be absorbed by the developer.

   (c)   The final street surface course, at the option of the City, may be applied one year later to allow for settling.
