A concrete or asphaltic concrete pavement shall be constructed in each street proposed to be dedicated. The pavement material shall be as determined by the City Engineer. In certain special instances where it is proposed to use an existing dedicated street with an inadequate pavement as a principal access street to the proposed subdivision, the City may require that new pavement and sidewalks be constructed on the principal access streets at no expense to the City. The new pavement shall be built with a six-inch Ohio Department of Transportation (ODOT) Type 2A or Type 6 Portland cement concrete curb on each side of the pavement. The minimum section of the pavement shall be as follows, and shall be constructed in accordance with the Ohio Department of Transportation (ODOT) "Construction and Materials Specifications", as directed by the City Engineer.
PAVEMENT TYPES
(a) Concrete Pavement.
(1) A seven inch minimum thickness per ODOT Item 451 and 452, excluding the base course.
(2) Tests will be made by a commercial testing laboratory, at the expense of the contractor, twice each day. Tests will be done for air content and slump. Each test will consist of three cylinders, one to be broken at seven days and the other two cylinders will be broken at 28 days.
(b) Asphaltic Concrete Pavement.
Subgrade CBR Value* | Pavement Thickness (inches), excluding base course | ||
Item 301 | Item 402 | Item 404 | |
3 | 6 | 2 | 1-1/2 |
5 | 5 | 1-1/2 | 1-1/2 |
7 | 4-1/2 | 1-1/2 | 1-1/2 |
10 and more | 4 | 1-1/2 | 1-1/2 |
*To be determined by laboratory analysis and field verification prior to pavement construction. All testing shall be at the expense of the contractor. | |||
(c) At all street intersections, the pavement shall be joined by a circular curve or turnout of a minimum radius per Table 4 in Section 1135.10, measured to the outside of the pavement. It is recommended that wherever feasible, the radius point of the pavement turnout should be made coincident with that of the right-of-way.
(d) In order to insure a minimum sight distance of 500 feet and with due allowance for reasonable vertical curves, the maximum gradient shall be 8%.
(e) In order to have a good drainage, no longitudinal pavement grade shall be less than 0.5%.
(f) Changes of gradient of 1% or more shall be connected by a vertical curve.
(g) A four-inch or six-inch curb underdrain, Ohio Department of Transportation (ODOT) Item 605, of material acceptable to the City Engineer with a suitable granular backfill shall be provided on the outside of each curb to adequately drain the subbase or subgrade.
