Construction of all residential streets in the City shall conform to the minimum standards set forth in this section.
(a) Grading. The road shall be graded the entire width of the right of way. All backsloping shall be done on private property. Grading shall conform to the typical section on file in the City Hall and shall meet the requirements of Roadway Excavation and Embankment, in the State of Ohio Department of Transportation Construction and Material Specifications, current edition.
(b) Concrete Pavement. The pavement shall be a minimum of twenty-seven feet wide, measured back to back of the integral curbs, and shall be constructed in accordance with all applicable Ohio Department of Transportation Specifications, including, but not limited to, the following ODOT material and method specification items:
(1) Item 203 - compacted subgrade;
(2) Item 304 - 4 inch aggregate base;
(3) Item 451 - 7 inch reinforced (78# WWF) concrete pavement;
(4) Item 609 - 6 inch upright concrete curb;
(5) Item 605 - 4 inch perforated underdrain with granular filter aggregate no. 8.
Note: All joints to be installed per ODOT requirements.
(c) Asphalt Concrete Pavement. The pavement shall be a minimum of twenty-three feet wide measured between the inside edges of the gutters, with eleven and one-half foot wide individual lanes with a minimum two foot wide concrete curb and gutter on each side. The concrete combined curb and gutter shall be a minimum of two feet wide, making a total minimum pavement width of twenty-seven feet back to back of the curbs, and shall be constructed in accordance with all applicable Ohio Department of Transportation Specifications, including, but not limited to, the following ODOT material and method specification items:
(1) Item 203 - compacted subgrade;
(2) Item 304 - 6 inch aggregate base;
(3) Item 301 - 5 inch bituminous aggregate base;
(4) Item 407 - tack coat;
(5) Item 448 - 1½ inch asphaltic concrete surface course;
(6) Item 609 - upright concrete curb and gutter, type 2;
(7) Item 605 - 4 inch perforated underdrain with granular filter aggregate no. 8.
(Ord. 14-2005. Passed 3-14-05.)
(d) Alternate pavement design. The following pavement design is an alternate to the desing listed in subsection (c), which shall be constructed in accordance with the ODOT material and method specific items. With this design, Item 304 may be reduced to a minimum of four inches aggregate base. Item 206, ODOT Geotechnical Bulletin GB-1, Plan Subgrades, dated June 29, 2005, shall be followed. In addition, a subsurface investigation and sub-base stabilization design summarized in a report, signed and sealed by a registered geotechnical engineer with recommendations for the specific site shall be submitted to and approved by the Municipal Engineer.
(1) Asphalt concrete pavement with a chemically stabilized subgrade. The pavement shall be a minimum of 23 feet wide measured between the inside edges of the gutters, with 11.5 foot wide individual lanes with a minimum two foot wide concrete curb and gutter on each side. The combined curb and gutter shall be a minimum of two feet wide, making a total minimum pavement width of 27 feet back to back of the curbs, and shall be constructed in accordance with all applicable Ohio Department of Transportation Specifications (ODOT), including but not limited to the following ODOT material and specification items.
(2) Ohio Department of Transportation Specifications.
A. Item 206 - Proofrolling. Subgrades shall be proofrolled with a loaded tandem dump truck with a gross weight of 60,000 pounds minimum (30 tons) to determine the stability of the soils. The movement of the subgrade will be observed for any deflection of the subgrade. A zero (0) deflection of the subgrade dictates suitability of placemenet of the overlaying layers of pavement. Whereas a deflection does occur, the area will be marked out one-half width by the length of the deflection for repair. The depth of rutting or pumping of subgrade will dictate the depth of the repair. The depth of repair shall be a minimum of six inches to qualify for the consideration in the pavement structure.
B. Item 206 - Chemically stabilized subgrade, 6" minimum. Material for the chemically stabilized subgrade shall be determined by a contractor design in accordance with ODOT Item 206.06. The contractor shall blend cement, lime by-product or a combination of cement and lime by-product with the site soil to determine the required percentage and mixture for the project. The minimum strength of test samples must meet a five days unconfined compressive strength of 200 psi. For quality control cylinder samples taken f rom the chemically stabilized streets shall be tested at five days to confirm that they comply with the above criteria.
C. Item 206 - Curing coat. If deemed necessary by the Municipal Engineer, a curing coat is required. The application of a curing coat may not be required on new residential subgrades with little or no traffic. The material for curing shall be in accordance with ODOT Item 206.05.D.
D. Item 304 - Aggregate base. Four inches is required.
E. Item 301 - Bituminous aggregate base. Five inches is required.
F. Item 407 - Tack coat.
G. Item 448 - Asphaltic concrete surface course. One and one-half inches is required.
H. Item 609 - Upright concrete curb and gutter. Type 2 (T = 7").
I. Item 605 - Perforated underdrain. Four inches perforated underdrain with granular filter aggregate number 8.
