Sidewalks and Bikeways

Description

608.01This work consists of the construction of bituminous or concrete sidewalks, bikeways,

and curb ramps per these specifications and in conformity with the lines and grades shown on the plans or established. Materials

608.02Materials shall meet the requirements specified in the following subsections:

Joint Fillers 705.01 Bed Course Material 703.07

Concrete for sidewalks, bikeways, and curb ramps shall be Class B and meet the requirements of Section 601.

Bituminous material for sidewalks, bikeways, and curb ramps shall meet the requirements of

Concrete and bituminous mixes will be subject to inspection and tests as required to ensure compliance with quality requirements. Construction Requirements

608.03Concrete Sidewalks and Bikeways

the installation and bracing of the forms. The foundation shall be shaped and compacted to a firm even surface conforming to the section shown on the plans or as staked. When the Engineer determines that material is uncompactable, the material shall be removed and replaced per subsection 206.03.

full depth of the concrete. All forms shall be straight, free from warp, and of sufficient strength to resist the pressure of the concrete without springing. Bracing and staking of forms shall be such that the forms remain in both horizontal and vertical alignment until their removal. A satisfactory slip-form method may be used.

placing of the concrete. The proportioning, mixing, and placing of the concrete shall be per the requirements for the class of concrete specified.

transverse broom finish. Plastering of the surface will not be permitted. All required hand finishing shall be performed in conformance with subsection 601.12(a). All outside edges of the slab and all joints shall be edged with a 1/4-inch radius-edging tool.

inch-thick full depth, preformed expansion joint filler. The sidewalk or bikeway shall be divided into sections by dummy joints formed by a jointing tool or other acceptable means as directed. These dummy joints shall extend into the concrete for at least a quarter of the depth and shall be approximately 1/8 inch wide. Dummy joints shall be spaced at intervals approximately equal to the width of the sidewalk or bikeway.

608.04 Construction joints shall be formed around all appurtenances such as manholes, and utility poles, extending into and through the sidewalk. Preformed expansion joint filler 1/2 inch thick shall be installed in these joints. Expansion joint filler 1/2 inch thick or the thickness indicated shall be installed between new concrete and any fixed structure such as a building or bridge. This expansion joint material shall extend for the full depth of the contact surface.

moistened and kept moist for three days, or they shall be cured by the use of membrane- forming curing compound. The method and details of curing shall be subject to the approval of the Engineer. During the curing period, all traffic, both pedestrian and vehicular, shall be excluded. Vehicular traffic shall be excluded for such additional time as the Engineer may direct.

608.04Bituminous Sidewalks and Bikeways

(a) and (b)

depth and each layer shall be thoroughly compacted.

on the compacted bed course in one or more courses as indicated to give the required depth when rolled. When practicable, spreading, finishing, and compaction shall be accomplished by equipment conforming to the requirements of Section 401. When the Engineer determines such equipment is not practicable, bituminous material may be spread by small or special pavers, by spreader boxes, or by blade graders and may be compacted by small self-propelled rollers or vibratory compactors acceptable to the Engineer. In areas inaccessible to the roller, hand or mechanical tamping will be permitted. Bituminous material shall be uniformly compacted. The Contractor shall state at the Pre-construction Conference what type of paving equipment will be used.

Method of Measurement

608.05Concrete sidewalks, bikeways, and curb ramps will be measured by the square yard

of finished surface. Bituminous sidewalks, bikeways, and curb ramps will be measured by the ton of bituminous mixture placed.

Basis of Payment

608.06The accepted quantities will be paid for at the contract unit price for each of the pay

items listed below that appear in the bid schedule. Payment will be made under:

Pay Item Pay Unit Concrete Sidewalk Square Yard Bituminous Sidewalk Ton Concrete Curb Ramp Square Yard Bituminous Curb Ramp Ton Concrete Bikeway Square Yard Bituminous Bikeway Ton

Bed course material will be measured and paid for per Section 206.

All work necessary and incidental to the construction of sidewalks, bikeways, and curb ramps will not be measured and paid for separately but shall be included in the work.
