Chapter 98-8 — PAVEMENT

The structural design of the pavement includes the determination of the thickness and type of subbase, base, and surfacing to be placed over the basement soil according to an accepted method used by the public works department. The public works department shall specify the structural design for the streets.

(Ord. 78-5).

The subdivider, at the subdivider's expense, may make tests of the soil over which the surfacing and base is to be constructed and furnish the test reports to the public works department for use in determining a preliminary structural design of the roadbed. Tests and pavement structural design will be made by the public works department after the payment of the inspection fee.

(Ord. No. 2024-23, § III(Exh. A), 12-3-24; Ord. 78-5).

In no case shall the thickness of the base material be less than five-tenths of one foot, nor shall the thickness of asphalt concrete surfacing be less than fifteen-hundredths of a foot.

(Ord. 78-5).

The pavement crown and geometric design of the street cross-section shall be shown and dimensioned on the improvement plans, and shall conform to accepted design standards. The minimum cross-slope shall be two percent. On street grades over six percent, a five percent cross-slope shall be provided adjacent to the curb and gutter for a distance of not less than ten feet from the face of the curb, reduction of which may be approved by the public works department. Crown requirements are waived for private roads.

(Ord. 78-5).
