(B) Rigid type pavement (cement concrete).
(1) Minimum design characteristics of rigid street pavement shall be as follows:
Concrete *(Reinforced) | Major Residential | Minor Residential | Cul-de-Sac |
Uniform thickness | **8 in. to 9 in. | 7-1/2 in. | 6 in. |
Leveling course | 1 in. | 1 in. | 1 in. |
Compaction | 95% mod. proctor | 95% mod. proctor | 95% mod. proctor |
*Wire mesh continuous between expansion joints with steel dowels at expansion joints | |||
**9 in. required at all intersections and where heavy truck traffic is proposed by developer or subdivider | |||
(2) The Plan Commission shall determine the subbase requirements for rigid pavement based upon the area’s characteristics. The developer shall submit with the preliminary plan supporting data on the subbase being proposed for rigid pavement streets. Final required pavement must be installed prior to final plat approval.
