3590Multi-Component Liquid Pavement Markings

3590.1SCOPE

Provide reflectorized white and yellow multi-component, 100 percent solids multi-component liquid pavement markings that are free of toxic heavy metals for installation on bituminous and concrete pavement surfaces.

3590.2REQUIREMENTS

A General Apply multi-component liquid pavement markings including lines, legends, symbols, crosswalks, and stop lines, in accordance with 2582, “Pavement Markings.” Use Materials capable of producing pavement markings of specified thickness in accordance with 2582.3B.4, “Thickness Requirements,” and retroreflectivity in accordance with 2582.3C.3, “Retroreflectivity,” unless otherwise required by the Contract. Provide yellow markings distinguishable from white markings in the dark. Provide slow dry Material from the multi-component liquid pavement markings APL, unless otherwise required by the Contract. The Department will not require the mixing of individual components before use if stored for no greater than 12 months.

B Multi-Component Liquid Material Provide multi-component liquid Material meeting the following requirements and characteristics:

mils WFT application rate B.1 Adhesion Capabilities Provide Material meeting the adhesion requirements of the American Concrete Institute Committee 403 when tested on Portland cement concrete. Apply multi-component liquid pavement markings during the test to concrete pavements with a tensile strength of at least 300 psi and ensure the failure of the system occurs in the concrete during testing. B.2 Abrasion Resistance Provide Material with an abrasion resistance wear index no greater than 82 when tested in accordance with ASTM C501, Standard Test Method for Relative Resistance to Wear of Unglazed Ceramic Tile by the Taber Abraser, with a CS 17 wheel under a load of 1,000 grams for 1,000 cycles. The Department defines the wear index as the weight in milligrams of Material abraded from the sample under the test conditions. B.3 Hardness Provide Material with a Type D durometer hardness from 75 to 90 when tested in accordance with ASTM D2240, Standard Test Method for Rubber Property – Durometer Hardness, after curing for 72 hours at 73°F ±4°F.

B.4 Tensile Strength For epoxy-amine based multi-component systems, including variations of this base chemistry, provide Material with a tensile strength of at least 6,000 psi when tested in accordance with ASTM D638, Standard Test Method for Tensile Properties of Plastics, after curing for 72 hours at 73°F ±4°F. For polyurea based multi-component systems provide Material with a tensile strength of at least 3,000 psi when tested in accordance with ASTM D638 after curing for 72 hours at 73°F ±4°F. B.5 Compressive Strength For epoxy-amine based multi-component systems, including variations of this base chemistry, provide Material with a compressive strength of at least 12,000 psi when tested in accordance with ASTM D695, Standard Test Method for Compressive Properties of Rigid Plastics, after curing for 72 hours at 73°F ±4°F.

3590.3SAMPLING AND TESTING

Test the daylight directional reflectance and the color meeting the requirements of ASTM E1349, Standard Test Method for Reflectance Factor and Color by Spectrophotometry Using Bidirectional (45 °:0° or 0°:45°) Geometry. Provide 1 pint samples of each manufacturer’s lot or batch of Material when manufactured to the Department. Provide 1 pint samples of Part A (yellow/white multi-component liquid) and Part B (catalyst) to the Materials Laboratory. Mark the samples with the following information:

Submit to the Engineer a manufacturer’s Certificate of Compliance for each components of the multi-component liquid pavement marking system. Mark containers for epoxy components with the following information:
