(A) General. All privately constructed roadways to become part of the county highway system:
(1) Must be set forth in a plot plan prepared by a registered state land surveyor;
(2) Must receive full approval of the county’s Planning and Zoning Board;
(3) Must have obtained all required permits;
(4) Must have a verified inspection report from the County Highway Superintendent stating that all the construction requirements have been met and that the Superintendent has inspected each phase of the road construction;
(5) Must have tendered an executed warranty deed, with title opinion, made out to the County Commissioners with at least a 50-foot right-of-way;
(6) Must have submitted a final, as constructed, plot plan; and
(7) Must have the County Commissioners formally accept the roadway.
(B) Roadway to be constructed. All persons seeking preliminary approval of a proposed privately-built road to be entered into the county highway system must comply with the minimum requirements, those being divisions (A)(1), (A)(2), (A)(3) and (A)(5) above and post a performance bond in the amount of 125% of the projected cost of construction of the roadway.
(C) Roadway construction specifications. The privately-built roadway must:
(1) Have a 50-foot wide (25 feet each way from the center line of the roadway) right-of-way, free and clear of obstruction other than those approved by the County Highway Superintendent, in writing;
(2) Have a 20-foot wide base of at least nine inches in thickness, made of materials approved by the County Highway Superintendent, in writing;
(3) Have a 16-foot wide asphalt paved surface of at least four inches in thickness of materials approved by the County Highway Superintendent, in writing;
(4) Have all necessary culverts, ditches, bridges and the like, to ensure proper drainage, as well as having all ditches sloped such that their maintenance will not be unreasonable, and the County Highway Superintendent must certify in writing that this division (C)(4) has been properly executed;
(5) All roads that dead end must have a turn-around which is adequate to allow a school bus to safely turn-around as approved by the County Highway Superintendent;
(6) Meet all state and county requirements in the construction of the roadway and be verified in writing by the owner that all these requirements have been met; and
(7) The roadway must be in good repair at the time of acceptance.
(D) Provisions for new roads in the county.
(1) Unless otherwise provided, the roadbed below subgrade shall be so constructed that it will have, as nearly as possible uniform density throughout. It shall be rolled with a ten-ton roller or with other approved compacting equipment capable of providing a smooth, even subgrade surface.
(2) The materials used may be crushed stone, crushed or uncrushed gravel. If crushed or uncrushed gravel is used a total of seven inches will be laid. The #73 rock will be used on two inches topcoat of subgrade and will be compacted to a minimum of 100% maximum dry density.
(3) Surface requirement at the time a base or pavement is to be placed on subbase, the subbase shall meet the required density, as set herein and also, the surface tolerance for subbase as required in these specifications for the kind of base or pavement to be placed thereon.
(4) The road itself shall be a minimum of 20 feet. It shall have four feet shoulders on each side with a one-inch fall to the foot making a four-inch fall in four feet.
(5) The slope to the bottom of the ditch shall be a one-foot fall to three feet horizontal or a one to three slope.
(6) The back slope shall be no less than a one to one to a one and one-half slope. All utilities buried along the road shall not be more than two feet from bituminous and shall not be less than two feet deep. There shall not be any culverts less than 15-inch and less than the five-year estimated soil and water runoff.
(7) Rollers shall be of the steel wheel and/or pneumatic tire type and shall be in good condition, capable of reversing without backlash. They shall be operated at speeds not to exceed three mph for static rollers and two and one-half mph for vibratory rollers and slow enough to avoid displacement of the bituminous mixture. No container containing fuel oil shall be hauled on any roller.
(8) Two axle tandem rollers used in this work shall be self-propelled, have two wheels weigh no less than ten tons, have all wheels equipped with scrapers which shall be used as needed to keep the surfaces clean, be equipped with devices to keep the wheels wet enough to prevent material sticking to them, be able to stop and start without jerking, having steering devices capable of easily and accurately guiding the roller along desired lines and have devices to prevent oil, grease or fuel from dropping onto the surface.
(9) The mixture shall be laid upon an approved surface, spread and struck off to the grade and elevation established. Bituminous pavers shall be used to distribute the mixture either over the entire width or over such partial width as may be practicable. The longitudinal joint in one layer shall offset that in the layer immediately below by approximately six inches when practicable. However, the joint in the top layer shall be at the center line of the pavement if the roadway comprises two lanes of width or at lane lines if the roadway is more than two lanes in width.
(10) On areas where irregularities or unavoidable obstacles make the use of mechanical spreading and finishing equipment impracticable, the mixture shall be spread, raked and luted by hand tools. For such areas the mixture shall be dumped, spread and screeded to give the required compacted thickness.
(11) Immediately after the bituminous mixture has been spread, struck off and surface irregularities adjusted, it shall be compacted thoroughly by rolling. The surface shall be rolled when the mixture is in the proper condition and when rolling does not cause undue displacement, cracking or shoving.
(12) Rollers shall move at a slow but uniform speed with the drive roll or wheels nearest the paver. Rolling shall be continued until compaction is completed and all roller marks are eliminated.
(13) Any displacement occurring as a result of reversing the direction of a roller, or from other causes, shall be corrected at once by the use of rakes and addition of fresh mixture when required. Care shall be exercised in rolling not to displace the line and grade of the edges of the bituminous mixture.
(14) To prevent adhesion of the mixture to the steel-wheel rollers, the wheels shall be kept properly moistened with water or water mixed with very small quantities of detergent or other approved material. Excess liquid will not be permitted. Any mixture that becomes loose and broke, mixed with dirt or is in any way defective shall be removed and replaced with fresh hot mixture, which shall be compacted with the surrounding area. Any area showing an excess or deficiency of bituminous material shall be removed and replaced. The bituminous mixture shall be completely compacted within 30 minutes of the time it is spread. No mixture shall be dispatched from the plant so late in the day that it cannot be spread and compacted in daylight of that same day.
