608.01 Description . This work consists of constructing concrete sidewalks on a prepared
subgrade in accordance w ith the plans and specifications. This work may also include the placement of detectable warning panels / trun cated domes in concrete sidewalk as shown on the plans or as directed by the Engineer. Lines and grades shall be as shown on the plans or established. "Subgrade" in this section shall mean the prepared foundation on which the sidewalk is constructed. 608.02--Materials . All material furnished for use shall comply with appropriate requirements of the 700 series of these specifications, and the following: Concrete shall be Class B meeting the requirements of Section 804 or Class P or PA meeting the requirements of Section 501. Reinforcing steel shall meet the applicable requirements of Sections 602 and 711 and plan details. Detectable warning panels shall meet the requirements of plans, specifications, and the requirements of the Americans with Disabilities Act (ADA). The panels shall be precast, modular, or prefabricated.
608.03 Construction Requirements .
608.03.1 Equipment . The Contractor may use forms or, if requested in writing and
approved by the Engineer, an approved automatic extrusion type paving machine. Forms shall be wood or metal. If wood, they shall be dressed on all sides, and be free of bulges, warps, and loose knots. If metal, they shall be of approved section and have a flat surface on top. The depth of the forms shall be equal to the depth of the sidewalk. Adequate means shall be provided for securely fastening the ends of forms together. Prior to use, an automatic extrusion mach ine must be demonstrated to produce a consolidated concrete section conforming to th e dimensions, cross section, line, and grades shown on the plans or established.
608.03.2 Excavation and In-Grade Preparation . Excavation shall be made to the
required depth and to a width that will permit the installation and bracing of forms. The foundation shall be shaped and compacted at the proper moisture content to a firm, even surface conforming to the lines, grades, and sec tions shown on the plans or established. All soft, spongy, or other unsuitable materials encountered shall be removed and replaced with acceptable material.
608.03.3 Setting Forms . Forms shall be set to the required line and grade and rigidly
held in place by stakes or braces. Ends of ad joining form sections shall be flush. Forms and division plates shall be cleaned and o iled before placing concrete against them.
608.03.4 Handling, Measuring, Proportioning, and Mixing Materials . The method of
handling, measuring, proportioning, and mixing concrete materials shall conform to Section 501 or Section 804. Where reinforcement is required, it shall be placed in accordance with Section 602.
608.03.5 Placing Concrete . A template resting upon the side forms and having its lower
edge at the elevation of the subgrade shall be drawn along the forms to shape and grade the subgrade before concrete is deposited. The subgrade shall be moist and free of debris and foreign material before concrete is deposited upon it. The concrete mixture shall be placed on the prepared subgrade to the depth required to complete the sidewalk in one course. It shall then be vibrated and/or tamped and struck off with an approved straightedge resting upon the side forms and drawn forward with a sawing motion. The surface shall be given a Class 6 float finish as set out in Section 804. The edges of sidewalk shall be rounded with an edging tool having a radius of 1/2 inch. Expansion joints shall be edged with an edger having a radius of 1/4 inch.
608.03.6 Joints . Expansion joints shall be of the dimensions specified and shall be filled
with the type of premolded expansion joint filler specified. Sidewalks shall be divided into sections by dummy joints formed by a join ting tool or other acceptable means. These dummy joints shall extend into the concrete for at least one inch and shall be approximately 1/8 inch wide. Joints shall match as nearly as possible adjacent joints in curb or pavements. Dummy joints may be sawed in lieu of forming with a jointing tool. Construction joints shall be formed around all appurtenances such as manholes, utility poles, etc. extending into and through the sidewalk. Premolded expansion joint filler 1/4 inch thick shall be installed in these joints. Expansion joint filler of the thickness indicated shall be installed between concrete sidewalks and fixed structure such as a building or bridge. This expansion joint material shall extend for the full depth of the walk.
608.03.7 Protection and Curing . Concrete shall be protected and cured in accordance
with the requirements of Subsection 501.03.20 or by other approved methods. Placement, protection, and curing of concrete during cold or hot weather shall conform to the limitations, conditions, and requirements set out in Section 804.
608.03.8 Backfilling and Cleaning Up . When the concrete has set sufficiently, the sides
of the walk shall be backfilled and compact ed to the required elevation with suitable material. All surplus material shall be disposed of as directed, and the completed work and the site shall be left in a neat and presentable condition.
608.03.9 Detectable Warning Panel . Detectable warning panels shall be installed on the
concrete sidewalk at the locations shown on the detail drawings in the plans and in accordance with the manufacturer’s recommendations.
608.04 Me thod of Measurement . Concrete sidewalks of the type specified will be
measured for payment by the square yard. Transition slopes, turning space, and ramps necessary for ADA curb cuts will be measured as concrete sidewalk. Detectable warning panels will be measured by the square foot of actual panel placed. Concrete sidewalk under the panels will be paid for as sidewalk per square yard. Excavation, backfill, expansion joint material, and other miscellaneous items will not be measured for separate payment.
608.05 Basis of Payment . Concrete sidewalks, measured as prescribed above, will be
paid for at the contract unit price per square yard, which shall be full compensation for all labor, equipment, materials, and incidentals necessary to complete the work. Detectable warning panels, measured as prescrib ed above, will be paid for per square foot, which price shall be full compensation for all materials, labor, equipment, and incidentals necessary to complete the work. Payment will be made under: 608-A: Concrete Sidewalk, Without Reinforcement - per square yard 608-B: Concrete Sidewalk, With Reinforcement - per square yard 608-C: Detectable Warning Panels per square foot SECTION 609 - CONCRETE GUTTER, CURB, AND COMBINATION CURB AND GUTTER
609.01 Description . This work consists of constructing curb, gutter, and combination
curb and gutter in accordance w ith these specifications and in reasonably close conformity with the lines, grades, dimensions, and cross sections shown on the plans or as established.
609.02 Materials . Concrete for detached curb, gutter, and combination curb and gutter
shall meet the requirements of Section 601. Concrete for curbs integral with concrete
