The 408 Bituminous Prime Coat is required on all 303 and 304 items at a rate of .5 gallon per sq. yd.
(3) Pavement material testing. All paving materials shall be tested at the developer's or contractor's expense. Samples shall be taken and tested from the material source, or material producer, prior to construction. During construction, samples of materials being used shall be taken and tested at every third station of each pavement lane and at other locations as the City Engineer may request. All testing shall be done by an approved testing laboratory and in accordance with current Ohio Department of Transportation testing practices for material approval for highways. Three (3) copies of the laboratory report for each sample shall be submitted to the City Engineer.

(d) Vertical Curvature. Minimum clear sight distance of 200 feet.
(e) Curbs and Gutters. Curbs and gutters shall be provided on both edges of all pavement and shall be cast in place, concrete and constructed in accordance with Item 609, Combination Curb and Gutter Type 2.
Intersection Standards. All curbs at right-angle intersections shall have a minimum radius of twenty-five (25) feet measured to the back of the curb, except intersections involving arterial and collector streets, for which the City Engineer shall specify the radius. At intersections where the angle is other than ninety (90) degrees, the City Engineer shall specify the curb radius.
Where sidewalks are interrupted by curbs at street intersections or other locations, curb ramps shall be constructed at each pedestrian crosswalk. Curb ramps shall have non-slip surface texture and the design shall be in accordance with ODOT Standard Construction Drawing BP-12.
(f) Roadway Crown. Roadway Crown shall be 3/16 inches per foot from centerline to edge of pavement.
(g) Guard Rail and Seeding, etc. The necessity of guard rail, seeding, type of backfill or other special conditions, shall be determined with the assistance of the City Engineer before completion of the construction plan.

TYPES OF STREETS | WIDTH OF PAVEMENT |
Primary roads, arterial highways and streets | Variable 20'-48' * |
Collector streets as described in the Comprehensive Plan | 38 feet |
Local streets serving low-density suburban development of over two families per acre | 28 feet |
Industrial service roads and residential development of less than two families per acre | 24 feet |
* To conform to applicable cross sections of Major Highway Plan, as determined by Planning Commission and Engineer.
(i) Sidewalks. Concrete sidewalks are to be constructed and shall have a minimum width of four (4) feet and a minimum thickness of four (4) inches.
