CONSTRUCTION REQUIREMENTS

607.03General Requirements

The excavation shall be to the required depth and shape of the bottom of the type and size of the side ditch being constructed, the details of which are shown on the plans. All soft, yielding, or unsuitable materials encountered at the required excavation 20 elevation shall be removed and replaced wi th approved materials which shall be compacted and finished to a firm, smooth surface.

The applicable requirements of 605.04(b) shall apply to forms.

Placing, finishing, and cu ring shall be in accordance with 605.04 except the curing period shall be no less than 72 h. The finished surface need not be brushed.

Reinforcement will be required for all paved side ditch, cut-off-walls, and lugs as shown on the plans. 30

Paved side ditch transitions will be required at intersections with earth ditches and pipe culverts.

607.03

Transitions of 10 ft or less will be required between two different types of paved side ditches.

Cut-off wall and lug details shall be as shown on the plans. A cut-off wall shall be constructed at the beginning and end of any paved side ditch. Lugs shall be poured monolithic with paved side ditch on steep grades. Their locations shall be as shown on 40 the plans or as otherwise directed. Backfilling shall be in accordance with 605.04(g).

607.04Cement Concrete Gutter and Turnout

Concrete gutter and concrete gutter turnout shall be constructed as shown on the plans or where directed. Construction sha ll be in accordance w ith all applicable requirements set out herein for paved side ditch.

607.05Method of Measurement

Paved side ditch or cement concrete gutter will be measured by the linear foot along the centerline of the ditch per each type specified. Each cutoff wall or lug will 50 be measured as 8 lft of paved side ditch or cement concrete gutter. Paved side ditch transitions at earth ditches and pipe culverts will be measured as equivalent lengths in linear feet of the paved side ditch specified at each location. Transitions at the intersection of two different types of paved side ditch will be converted to equivalent lengths in linear feet of the larger type of paved side ditch specified at each site.

Reinforced concrete gutter turnout will be measured as 50 lft of concrete gutter. Additional length, if required, will be measured by the linear foot of concrete gutter.

607.06Basis of Payment 60

The accepted quantities of paved side ditch or cement concrete gutter of the type specified, including cutoff walls and lugs measured in accordance with 607.05, will be paid for at the contract unit price per linear foot complete in place. Concrete gutter turnout will be paid for at the contract unit price per linear foot for gutter, concrete, of the type specified.

Payment will be made under:
