526-1 Description.
Furnish and install architectural pavers in accordance with this Section.
526-2 Materials.
526-2.1 General: Architectural pavers shall meet the following requirements:
Table 526-1 Architectural Paver Requirements Proposed Use ASTM C902 (Brick Paver) ASTM C1272 (Brick Paver) ASTM C936 (Concrete Paver) Local Side Streets ( ≤ 35 mph Design Speed) Do Not Use X X Commercial Driveways Do Not Use X X Sidewalks and Medians X Do Not Use X Residential Driveways X Do Not Use X Ensure that the pavers are consistent in color, size, and appearance. Architectural paver type, pattern, shape and/or color will be in accordance with plan details, when specified.
526-2.2 Architectural Pavers - Roadway: For installations on roadways and
commercial driveways, p rovide architectural pavers having a minimum thickness of 3 -1/8 inch.
526-2.3 Architectural Pavers - Sidewalk: For installations on sidewalks, medians and
residential driveways, p rovide architectural pavers having a minimum thicknes s of 2-3/8 inch.
526-2.4 Bedding and Joint Sands: Provide clean, non -plastic bedding and joint sand,
free from deleterious or foreign matter, natural or manufactured from crushed rock. Ensure the bedding sand meets the grading requirements of ASTM C33 Standard Specification for Concrete Aggregate. Ensure the joint sand meets the grading requirements of ASTM C144 Standard Specification for Aggregate for Masonry Mortar. Bedding sand may be used for joint sand. Do not use joint sand for bedding sand.
526-2.5 Bedding and Joint Grouts: A suitable grout, in thickness specified by the
manufacturer and approved for use by the architectural paver manufacturer, may be substituted for either bedding sand, joint sand or both when specified in the Plans and appro ved by the Engineer.
526-3 Construction Methods.
526-3.1 General:
526-3.1 1 Submittals: For Architectural Pavers – Roadway, furnish full size
samples to the Engineer for approval prior to beginning placement. For Architectural Pavers - Sidewalk, submit to the Engineer a certification that the architectural pavers meet the requirements of this Section. In addition, for all architectural pavers , submit a certified sieve analysis for gradation comparing results of the bedding sand and joint sand with the requirements of ASTM C33 or ASTM C144 as applicable. FY 2023-24 Return to Table of Contents
526-3.1 2 Mock -ups: Prior to beginning placement, install a 6 foot by 6 foot
paver area following these specifications. This area will be used to determine surcharge of the bedding material layer, joint sizes, lines, laying patterns and colors of the job. This area will be adjacent to an edge treatment, incorporated into the work, and will be the standard from which the work will be judged.
526-3.1 3 Environmental Conditions: Cover stockpiled materials with
waterproof covering to prevent exposure to rainfall. Do not install bedding mater ials or architectural pavers during heavy rains or over wet substrata.
526-3.2 Installation: Install the architectural pavers in the following manner:
1.Spread the bedding material evenly over the base course and screed to plan thickness, not to exceed a thickness of 1 -1/2 inch. Do not disturb the screeded bedding material. Ensure placement of sufficient bedding material to stay ahead of the laid architectural pavers. Do not use the bedding material to fill depressions in the base course.
2.Lay archi tectural pavers in the pattern(s) shown in the Plans and maintain straight pattern lines.
3.Joints between the architectural pavers, on average, will be between 1/16 to 3/16 inch wide.
4.Fill gaps at the edges of the paved area with cut or edge archi tectural pavers.
5.When utilizing bedding and joint sand:
a.Use a low amplitude vibrator capable of 5,000 foot-pounds with 7 - 100 Hz frequencies to vibrate and compact architectural pavers into bedding sand.
b.Vibrate the architectural pavers, sw eeping dry joint sand into the joints and vibrating, until the joints are full. Do not vibrate within 3 feet of the unrestrained edges of the architectural pavers.
c.At the end of each day, all work within 3 feet of laying face must be left fully compa cted, with sand -filled joints.
d.Sweep off the excess sand.
6.Leave a final surface elevation of architectural pavers of 1/8 to 1/4 inch above adjacent drainage inlets, concrete collars or channels.
7.Do not permit the final surface elevations of the pavers to deviate more than 3/8 inch under a 10 foot long straightedge , or more than 1/8 inch between adjacent pavers.
526-4 Method of Measurement.
The quantity to be paid for will be the plan quantity, in square yards, for architectural pavers compl eted and accepted. No deduction will be made for the areas occupied by ornamental trees left within and any other areas occupied by manholes, inlets, drainage structures or by public utility appurtenances within the normal areas of the architectural pavers .
526-5 Basis of Payment.
Price and payment will be full compensation for all work, including all materials, equipment, labor, and incidentals necessary to complete the work. Payment shall be made under: Item No. 526 - 1- - Pavers, Architectural - per square yard. FY 2023-24 Return to Table of Contents SECTION 527 DETECTABLE WARNINGS
527-1 Description.
Detectable warnings are products used for the visually impaired and installed on newly constructed and/or existing concrete or asphalt walking surfaces (sidewalk curb ramps, sidewalks, shared use paths, etc.).
527-2 Materials.
Use detectable warnings as approved for use on uncured concrete, existing concrete, and asphalt surfaces. Use only products and materials appropriate for the surface on which they will be applied. Use safety yellow, brick r ed, or black colored d etectable warnings on concrete walking surfaces. Use safety yellow colored detectable warnings on asphalt walking surfaces. Use detectable warnings listed on the Department ’s Approved Product List ( APL) meeting the requirements of Section 974. Methods used to form detectable warnings in wet concrete will not be permitted.
527-3 Construction Requirements .
Prepare the surface and install detectable warnings in accordance with the manufacturer’s installation instructions, using material s and equipment recommended and approved by the manufacturer. Construct in accordance with Standard Plans, Index 522-002. Open the walking surface to pedestrian traffic within 72 hours for uncured concrete surfaces. Immediately open the walking surface to pedestrian traffic for asphalt and existing concrete surfaces. Surface color and texture shall be complete and uniform. Detectable warning s will be securely installed as recommended by the manufacturer and free from lifting, cracking, missing or partial domes, and with no significant defects. Surfaces shall not deviate more than 0.10 inch from a true plane.
527-4 Method of Measurement.
Detectable warnings will be paid by plan quantity , per square foot, furnished, installed and accepted.
527-5 Basis of Payment.
Price and payment will be full compensation for all work specified in this Section, including all labor, surface preparation, materials and incidentals necessary to complete the work Payment will be made under: Item No. 527 - 2- Detectable Warnings - per square foot.
