CONCRETE SIDEWALK S AND DRIVEWAYS
522-1 Description.
Construct concrete sidewalks and driveways in accordance with the Plans and the Standard Plans. Sidewalk will include curb ramps, landings, transition slopes, sidewalk curb, and edge beams.
522-2 Materials.
Meet the requirements specified in 520 -2 and the embankment utilization requirements of Standard Plans Index 120 -001.
522-3 Forms.
Provide forms as specified in 520 -3.
522-4 Foundation.
Shape and compact the foundation materials with suitable equipment to a firm, even surface, true to grade and cross -slope. Meet the testing frequency and maximum lift thickness requirements of Section 120. Record density test results in the Earthwork Records System (ERS) section of the Department’s database. Compact cut-and-fill areas within 1 foot beyond each side of the sidewalk or driveway , when right -of-way conditions allow . Compact the foundation material below the bottom of concrete for a minimum depth of 1 foot for cut areas, 1 foot for fill areas less than 1 foot, and 2 feet for all other fill areas to a density not less than 95% of the maximum density as determined by FM 1-T099. Compact the material in the remaining fill areas to match the adjacent area density.
522-5 Joints.
Install expansion and contraction joints in accordance with the Plans and the Standard Plans.
522-6 Placing Concrete.
Place the concrete as specified in 520 -5.
522-7 Finishing.
522-7.1 Screeding: Strike-off the concrete by means of a wood or metal screed, used
perpendicular to the forms, to obtain the required grade and remove surplus water and laitance.
522-7.2 Surface Requirements: Imprint concrete as detailed in the Plans, otherwise
provide a broom finish. Ensure that the surface variations are not more than 1/4 inch under a 10-foot straightedge or more than 1/8 inch on a 5 -foot transverse section. Finish the outer edges of the concrete with an edging tool having a radius of 1/2 inch.
522-7.3 Sidewalk Cross Slope Requirements: Construct sidewalk with cross slope as
shown in the Plans and Standard Plans. Sidewalks must have some cross slope, but no more than 2.0%, in either the positive or negative direction after construction.
522-8 Curing.
Cure the concrete as specified in 520 -8. FY 2023-24 Return to Table of Contents
522-9 Opening Sidewalk to Pedestrian Traffic.
Install detectable warnings, when shown in the Plans, in accordance with Section 527 on completed sections of sidewalk before opening to pedestrian traffic.
522-10 Method of Measurement.
The quantity to be paid will be plan quantity, in square yards, completed and accepted.
522-11 Basis of Payment.
Price and payment will be full compensation for all work specified in this Section. Excavation for new installations will be paid for under the items for the grading work on the project. Payment will be made under: Item No. 522 - Concrete Sidewalk s and Driveways - per square yard. FY 2023-24 Return to Table of Contents SECTION 523 PATTERNED PAVEMENT
523-1 Description.
Patterned pavement is defined as a post applied surface marking material to either the pavement surface or to an imprinted pavement surface.
523-2 Materials.
Use patterned pavement products listed on the Department ’s Approved Product List (APL) meeting the requirements of Section 974. Prior to installation, submit pattern and color samples to the Engineer for confirmation that the product meets the pattern and color specified in the Plans. Do not begin installation until acceptance by the Engineer. The Engineer will take random samples of all material in accordance with the Department’s Sampling, Testing and Reporting Guide schedule.
523-3 Construction Require ments.
Install patterned pavement on asphalt or concrete locations with the color and pattern as specified in the Plans. Prepare the surface and install patterned pavement in accordance with the manufacturer’s installation instructions, using materials an d equipment recommended and approved by the manufacturer. Install overlay products to a thickness not exceeding 180 mils. Patterns and v ariations within the installation shall comply with ADA requirements. Complete all utility, traffic loop detector, and other items requiring a cut and installation under the finished surface, prior to product installation. Protect treated surfaces from traffic and environmental effects until the product is completely installed, including drying and curing according to the manufacturer’s instructions. For installation on new asphalt roadways, apply patterned pavement a minimum of 14 days after placement of the adjacent pavement . Patterned pavements shall be weather resistant , friction resistant, and through normal wear, shall show no signs of failure due to tearing, stretching, rollback, blistering, excessive cracking, chipping, discoloration, poor adhesion to the pavement, pavement damage, or vehicular damage. Upon completion of the installatio n, the Engineer will check the area at random locations for geometric accuracy. If any of the chosen areas are found to be deficient, correct the entire patterned area at no additional cost to the Department. Submit certification to the engineer, includin g the APL number and that the patterned pavement was installed in accordance with the manufacturer’s installation instruction s and this Section.
523-4 Method of Measurement.
The quantity to be paid will be the plan quantity in square yards of patterned pavement, completed and accepted. No deduction will be made for areas occupied by landscaping, manholes, inlets, drainage structures, or by any public utility appurtenances within the area.
523-5 Basis of Payment.
Price and payment will be full compensation for all work specified in this Section. Payment will be made under: Item No. 523 - 3- Patterned Pavement - per square yard. FY 2023-24 Return to Table of Contents
