i.Intercoat Adhesion -The adhesion of the system shall be a minimum of 4B when tested in accordance with ASTM D3359, Method B. ii. Accelerated Weathering -After cycling 1000 hours there shall be no evidence of checking, cracking, rusting, or blistering. The degree of chalking shall not be less than No. 6 when tes ted according to ASTM G154. The color difference after 1000 hours shall be no more than five ΔE units. iii. Salt Fog -Testing shall be in accordance with ASTM B117. After 1000 hours of continuous exposure, there shall be no evidence of checking, cracking, rust ing, or blistering.
711.23 Material/System Approval :
711.23.1 The Division will develop an approved list of products meeting this specification.
This list will be placed on the Division’s website. The list may be based upon previous testing performed by the Division, or the Division may choose materials from the National Transportation Product Evaluation Program (NTPEP) and/or the North East Protective Coating Commi ttee (NEPCOAT) tested materials. Upon approval by the Division, further testing may not be required. The Division may request random samples to assure compliance with specification requirements. Any materials not previously tested by MCS&T Division, NTPEP, or NEPCOAT shall be submitted for evaluation and approval testing. Paints and coatings submitted for approval testing shall be furnished to the MCS&T Division in appropriate containers not holding more than one gallon of material. Each component s hall be labeled appropriately, and the following information shall be provided with the sample:
i.Name and address of Manufacturer ii. Trade Name or Trade Mark iii. Type of Paint iv. Lot or Batch number
v.Date of manufacturing vi. All SDS/PDS information pertaining to the mate rial vii. Reference to the Division’s Standard Specifications viii. One (1) one -gallon kit of product/thinner
711.23.2 Any samples for approval testing and all supporting documentation shall be
shipped to the address provided below: West Virginia Division of Highways Materials Control, Soils and Testing Paint Laboratory 190 Dry Branch Drive Charleston, West Virginia , 25306
711.24 through 711.39 -Blank
711.40 Temporary White Or Yellow Traffic Zone Paint :
Temporary Traffic Zone Paint shall be any commercially available white or yellow paint designe d for use on highways. The paint shall be applied with glass beads, designed by the manufacturer to be compatible with the paint. 826 711.40.1 -Color and Retroreflectivity Requirements: The Contractor may retest any areas or sections reported as being def icient, in the presence of a project inspector, in order to verify the deficiency of the areas or sections. However, the final decision in regards to requiring re -striping shall be at the Project Engineers discretion. Color : After the application of the glass beads or other retroreflective elements, each color installed shall fall within the boundaries created by the following CIE Chromaticity Coordinate Limits within three (3) and up to thirty (30) days after application: COLOR CIE CH ROMATICITY COORDINATE LIMITS 1 2 3 4 X Y X Y X Y X Y White 0.480 0.410 0.430 0.380 0.405 0.405 0.455 0.435 Yellow 0.575 0.425 0.508 0.415 0.473 0.453 0.510 0.490 Retroreflectivity : The markings shall be visibly retroreflective, under both dry conditions and conditions of moderate rainfall, within three (3) and up to thirty (30) days after application. The markings shall be readily visible when viewed with automobile headlights at night. Markings not meeting the above visual criteria shall be subject to replacement by the Contractor at no additional charge to the Division. If necessary, retroreflectivity readings representing an adequate sampling, to be determined by the Project Engineer, may be performed by Division personnel. Readings shall be taken with an LTL 2000, or approved equal, hand held Retroreflectometer. The markings shall have a minimum re troreflective reading of 150 mc/1x/m² within three (3) and up to thirty (30) days after application. A 5% tolerance with the stated minimum required retroreflectivity values shall be allowed when tested with a hand held retroreflectometer.
711.40.2 MAP-21 Section 1504 Requirements: Reflective elements that are
manufactured using glass and that are applied to temporary traffic zone paint shall meet all applicable state and federal requirements pertaining to materials content. Specifically, such elemen ts shall meet the requirements of Section 1504 of MAP -21. Prior to application of the markings, the Contractor shall provide certifications of compliance with Section 1504 of MAP -21 for all applicable reflective elements. These certifications shall be fro m each supplier of applicable reflective elements to be used on the project, and shall identify the reflective elements being used on the project by stating the identifier used by the supplier(s), such as the product name(s) or product code number(s). Each supplier’s certification shall be accompanied by a certification(s) from an independent testing laboratory. The lab certification(s) shall certify that a representative sample of the supplier’s product(s) has been tested, and that the product(s) meets the requirements of Section 1504 of MAP -21. The lab certification(s) shall provide clear indication that the products tested include the product(s) specified by the supplier(s) in their certification letter(s), and shall indicate the date(s) that the testing was performed. The date of testing for each product shall be one (1) year or less prior to the letting date of the Contract. The representative sample(s) tested are not required to be from the same batch or lot number assigned to the reflective elements us ed on the project.
