The Contractor shall provide markers produced f rom any suitable combination of uniformly mixed clays, shales, talcs, flints, feldspar s, or other inorganic Materials that meet the required properties. The Contractor shall provide markers thoroughly and evenly cure d and free from defects. 704-E.2.2 Non-Reflective Raised Pavement Markers: Finish Requir ements The Contractor shall provide non- reflective raised pavement ma rkers in accordance with Table 704-E.2.2:1, “Non-Reflective Raised Pavement Marker Requi rements.” Table 704-E.2.2:1 Non-Reflective Raised Pavement Marker Requirements Specific Intensity (mcd/lux/m2) Test White (A) Yellow (AY) Section 704-E: Raised And Recessed Pavement Markers Page 797 Table 704-E.2.2:1 Non-Reflective Raised Pavement Marker Requirements Specific Intensity (mcd/lux/m2) Test White (A) Yellow (AY) Directional reflectance, Glazed surface (min) ≥75 n/a Directional reflectance, Body of marker ≥65 n/a Yellow Index, Glazed surface (min) n/a ≤0.07 Yellow Index, Body of marker n/a ≤0.12 Purity n/a 76-96% Dominate wave length n/a 579-585μm Total luminous reflectance (Y value min) n/a ≥0.41 Autoclave resistance n/a Glaze shall not spall, craze, or peel Strength (min) n/a ≥1.5kip Water absorption (max) n/a ≤2.0% 704-E.2.3 Reflective Raised Pavement Markers The Contractor shall provide the prismatic reflector type of r eflective raised pavement markers consisting of a methyl methacrylate or suitably compoun ded acrylonitrile butadiene styrene shell that is filled with a mixture of an inert thermo- setting compound and filler Material. The Contractor shall ensure a smooth exterior surface of the shell containing one (1) or two (2) methyl methacrylate prismatic reflector faces of the specified color. 704-E.2.4 Reflective Raised Pavement Markers Requirements If illuminated by a motor vehicle headlight, ensure the reflec tors appear an approved white, yellow, or red in accordance with Table 704-E.2.4:1, “Re flectorized Raised Pavement Marker Requirements. ” The Department will reject markers with off-color reflection.

Ensure a smooth exterior surface of the shell containing one (1) or two (2) prismatic re flector faces of the specified color. The Contractor shall provide a reflector of either polycarbona te microprism sheeting or prismatic air cell reflective lens. The Contractor shall provi de a sealed, metallic backed reflector to prevent water penetration with a reflector face ar ea of 1/2 inch. 704-E.2.6 Temporary Reflective Raised Pavement Markers Requirem ents If illuminated by a motor vehicle headlight, ensure that the r eflectors appear an approved white, yellow, or red in accordance with Table 704-E.2.6:1, “Te mporary Reflective Raised Pavement Marker Requirements.” The Department will reject mark ers with off-color reflection.

The Contractor may substitute rapid-set epo xy adhesive or standard-set epoxy adhesive with approval from the Project Manager and at no additional cost to the Department. 704-E.3 CONSTRUCTION REQUIREMENTS 704-E.3.1 Application and Weather Limitations The Contractor shall set the raised pavement markers to the al ignment established by the Project Manager. The Contractor shall place reflective markers so that the refl ective face of the marker is perpendicular to a line parallel to the Roadway centerline. Th e Contractor shall not place pavement markers over longitudinal or transverse joints in the pavement surface. The Contractor shall place the adhesive and markers in accorda nce with manufacturer’s recommendations. When installing temporary reflective raised pavement markers, the Contractor shall insure that they are easily removed without heating or diamond grinding, and without damage to the pavement surface. 704-E.3.2 Plowable Raised Pavement Markers The Contractor shall accurately lay out the locations of saw-c ut slots on the pavement as per Project Plans, mill or cut slots for the plowable raised pa vement markers in accordance with the manufactures Specifications, install marker as per Sec tion 704-E.3.1 “Application and Weather Limitations.” The Contractor shall not install plowabl e markers on Bridge decks or concrete surfaces. 704-E.3.3 Equipment The Contractor shall use Equipment recommended by the manufact urer for the installation of raised pavement m arkers. For recessed markers, the Contactor shall use Equipment capable of cutting or milling slot in asphalt pavemen t. Cuts should be smooth and machine should not damage surrounding Roadway surface. 704-E.3.4 Surface Preparation For raised pavement markers, the Contractor shall clean by swe eping, high pressure air or water, the specified pavement locations of dirt, curing comp ound, grease, oil, moisture, loose, or unsound layers, paint, a nd Material that would advers ely affect the adhesive’s bond. For recessed pavement markers, the Contractor shall ensure tha t saw cut slots for plowable raised pavement markers are dry and free of loose Mate rial before applying the bituminous adhesive. 704-E.4 METHOD OF MEASUREMENT The Department will measure refl ective and non-reflective rais ed and recessed pavement markers by the each and will be paid by each. 704-E.5 BASIS OF PAYMENT Pay Item Pay Unit Reflective Raised Pavement Marker, Type ____ Each Non-reflective Raised Pavement Marker, Type ____ Each Temporary Reflective Raised Pavement Marker, Type ____ Each Plowable Reflective Raised Pavement Marker, Type ____ Each 704-E.5.1 Work Included in Payment The following Work and items will be considered as included in the payment for the main items and will not be measured or paid for separately: 1. Furnishing, mixing, and applying adhesive or primers; 2. Standard surface preparation; 3. Maintaining and protecting t he pavement markings from traffi c during the marking operations; and 4.
