840PAVEMENT MARKERS

840.01DESCRIPTION. This section covers the material requirements for snow-

plowable raised pavement markers, inlaid pavement markers, replacement lenses, and temporary surface-mounted raised pavement markers. 840.02 GENERAL. Use pavement markers conforming to the following types.

840.02.01 Type IV Markers. Type IV markers are lenses (mono or bi-

directional) installed in grooves of inlaid markers and replacement lenses installed in Type V marker castings.

.02 Type V Markers. Type V markers consist of an iron casting with a

Type IV marker (mono or bi-directional) attached.

.03 Type IVA Markers. Type IVA markers are surface-mounted lenses

(mono or bi-directional) for temporary use in work zones. 840.03 APPROVAL. The Department will approve pavement markers based on conformance to KM 64-206 and the requirements of this section.

840.04PACKAGING. Suitably and substantially package all materials with the name

and address of the manufacturer and vendor, cont ract or purchase number, kind of material, trade name, and net contents plainly marked on each package.

840.05CERTIFICATION. Submit a manufacturer’s certification stating conformance

to the requirements of this section for each shipment of pavement markers delivered for use on projects. Clearly state the manufacturer, product name, product code, type, and color as listed in the Department’s List of Approved Materials. Identify the lot number(s) and quantity of pavement markers delivered. Provide a certification from the adhesive manufacturer stating the adhesive conforms to the requirements of the marker manufacturer and the minimum application temperature at which the adhesive can be successfully applied. Identify the lot number(s) and expiration date of the adhesive.

840.06ACCEPTANCE. The Department will accept pavement markers based on

verification of inclusion on the Department’s List of Approved Materials and compliance of the manufacturer’s certification. The Department will accept adhesive based on the compliance of the manufacturer’s certification and verification that the adhesive has not exceeded its expiration date.

841.01DESCRIPTION. This section covers Styrene-Butadiene latex admixtures for

concrete bridge deck overlays.

841.02GENERAL. Use a certified independent laboratory to conduct annual testing

and evaluation of Styrene-Butadiene latex admixtures as described in the Prequalification Test Program in the U.S. Department of Transportation Research Report No. FHWA-RD-78-35. Submit the certified test results along with a 5-gallon sample of the latex admixture to the Department’s Division of Materials. Use a latex admixture that is produced in the United States. Use only latex admixtures that are free of chlorides.

841.03APPROVAL. The Department will approve latex admixtures based upon

conformance of the required independent laboratory data and test results obtained by the Department to the requirements of FHWA-RD-78-35 and this section.. Submit independent laboratory data conducted within one year of the date of product submittal for Department approval. Obtain Department approval for each latex admixture annually. .

841.04PACKAGING. Package and store the latex admixture in containers and storage

facilities that protect the material from freezing and from temperatures above 85 °F. When storing outside of buildings during moderate temperatures, keep the material shaded and away from direct sunlight. Do not use any latex admixture exposed to freezing temperatures without approval from the Division of Materials.

841.05CERTIFICATION. Submit manufacturer’s certification stating conformance to

the requirements of this section for each shipment of latex admixture delivered for use on projects. Clearly state the manufacturer, pro duct name, and product code as listed in the Department’s List of Approved Materials. Identify the lot number(s), weight percent solids, pH, surface tension, expiration date, and quantity for each lot of latex admixture delivered.

841.06ACCEPTANCE. The Department will accept latex admixtures based on

verification of inclusion on the Department’s List of Approved Materials and compliance of the manufacturer’s certification. The Department reserves the right to sample and test latex admixtures, at the discretion of the Engineer, in accordance with the Department’s Field Sampling and Testing Manual. Do not accept latex admixture that has been exposed to freezing temperatures.
