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 SECTION 524 CONCRETE DITCH AND SLOPE PAVEMENT
524-1 Description.
Construct concrete pavement in the flow channel of drainage ditches and on slopes as shown on the Plans and in accordance with the Standard Plans .

524-3 Forms.
Provide forms as specified in 520 -3.
524-4 Foundation.
Shape and compact the foundation materials, upon which the pavement is to be constructed, to a firm, even surface, true to grade and cross slope. Dispose of surplus material.
524-5 Joints and Weep Holes.
524-5.1 Joints:
524-5.1 1 Joints in Ditch Pavement: Construct formed (construction joint) or
tooled contraction joints, spaced at 25 feet maximum intervals. Open joints are prohibited. Construct expansion joints with 1/2 -inch preformed joint filler at all inlets, endwalls, and at intervals o f not more than 200 feet.
524-5.1 2 Joints in Slope Pavement: Form open or tooled (dummy) type joints
as shown in the Plans. Form open joints by staking a metal bulkhead in place and placing the concrete on both sides of it. When the concrete has set suf ficiently to preserve the width and shape of the joints, remove the bulkhead. Upon finishing the pavement over the joint, open and edge the slot with a tool having a 1/4 -inch radius.
524-5.2 Method of Placing Slope Pavement: Place slope pavement in vertic al strips,
4 feet, plus or minus 1 inch, wide, except taper radii strips from the 4 -foot width at the bottom to a minimum width of 1 foot at the top. Score the strips horizontally at intervals of 2 feet, plus or minus 1 inch, with a tool having a double 1/ 4-inch radius. Edge construction joints between strips with a tool having a 1/4 -inch radius. The Engineer will allow construction joints at horizontal scorings.
524-5.3 Weep Holes: Locate and construct weep holes as shown in the Plans. Construct
weep hole s at the toe of slope for all slope pavements.
524-5.4 Filter Fabric: Place filter fabric directly beneath all concrete ditch pavement for
the entire length and width of the pavement, regardless of the pavement thickness. Place filter fabric below weep ho le aggregate to form a mat continuous with the pavement filter fabric or underlapping the pavement filter fabric, if present. FY 2023-24 Return to Table of Contents
