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.

530-1 Description.
530-1.1 Riprap: Construct riprap composed of sand -cement or rubble (consisting of
broken stone or broken concrete) as shown in the Standard Plans and in the Plans.
530-1.2 Articulating Concrete Block (ACB) Revetment Systems: Furnish and install
an ACB revetment system in accordance with this Section and in conformance with the lines, grades, design, and dimensions shown in the Plans. Submit vendor drawings for review and approval by the Engineer. Submit signed and sealed calculations of the block and cable sizing design for approval. Comply with the National Concrete Masonry Association’s Design Manual for Articulating Concrete Block Revetment Systems, Second Edition, or the National Highway Institute, Hydraulic Engineering Circular (HEC) No. 23, Publication No. FHWA NHI 09-110. Use a minimum Factor of Safety of 1.5 and 0.5 inch for the block projection. Blocks must be open cell and non -tapered unless otherwise stated in the Plans. Revetment cabling must be bi -directional or, for mono -directional cabling, the block instal lation must include a permanent mechanism within the block matrix to prevent lateral displacement of the installed blocks. Cabling must be polyester and free to move within the block. Use only ACB revetment systems currently listed on the Department’s A pproved Product List (APL). Manufacturers seeking evaluation of their product shall submit an application in accordance with Section 6, and include certified test reports from an independent test laboratory certifying the ACB revetment system meets the req uirements of this Section. If the ACB revetment system is intended for use as bridge abutment protection, include the following drawings with the APL submittal:
1.At the corner transition between the front and side slopes .
2.For anchorages, geote xtile fabric, treatment of voids between adjacent blocks, limits on void size between adjacent blocks and other special details required to successfully install the ACB .
3.For areas adjacent to bridge abutments, detail mat placement around curves, con nections, protection of mat ends , and splicing of mat.
530-1.3 Gabions: Furnish and install gabions, including gabion baskets and gabion
mattresses, filled with rock in accordance with this Section and in conformance with the lines, grades, design, and dimensions shown in the Plans .
