Description
608.01 This 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
608.02 Materials 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 Section 403. Concrete and bituminous mixes will be subject to inspection and tests as required to ensure compliance with quality requirements. Construction Requirements
608.03 Concrete Sidewalks and Bikeways.
a.Excavation. Excavation shall be made to the required depth and to a width that will permit 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.
b.Forms. Forms shall be of wood, metal, or other suitable material, and shall extend for the 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.
c.Placing Concrete. The foundation shall be thoroughly moistened immediately before the placing of the concrete. The proportioning, mixing, and placing of the concrete shall be per the requirements for the class of concrete specified.
d.Finishing. The surface shall be floated with a wooden or magnesium float and given a 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.
e.Joints. Expansion joints, at intervals of not more than 500 feet, shall be filled with 1/2- 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. 608-1 608.04 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.
f.Curing. Immediately upon completion of the finishing, sidewalks and bikeways shall be 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.
608.04 Bituminous Sidewalks and Bikeways.
a.Excavation and Forms. Excavation and forms shall meet the requirements of subsection 608.03(a) and (b).
b.Bed Course. Bed course material shall be placed in layers not exceeding 4 inches in depth and each layer shall be thoroughly compacted.
c.Placing Bituminous Material. Bituminous sidewalk and bikeway material shall be placed 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
608.05 Concrete 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. 608-2 608.06 Basis of Payment
608.06 The 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. 608-3 608.06 This Page Intentionally Left Blank 608-4 609.01
