IL SCOPE:

This specification describes 100%acrylic polymer type, low VOC, fastdrying, white waterborne traffic paintsthat can be used on previously paintedareas, on bituminous and Portlandcement concrete pavements. Thisspecification covers two types of paint:

• white striping traffic paint• white marking traffic paint

It is the intent of these specificationsthat the furnished paint shall have theconcept of being a "high-build" product.

III. GENERAL

The paint shall be formulated andprocessed specifically for service as abinder for beads, in such a manner as toproduce maximum adhesion, refraction,and reflection. Any capillary action ofthe paint shall not be such as to causecomplete coverage of the beads.

GENERAL

The paint shall be well mixed in themanufacturing process and shall beproperly ground when incorporating thepigments in order to conform to therequirements as specified.

The paint shall not liver, thicken, curdle,gel, settle excessively, or otherwiseshow any objectionable properties afterperiods of storage of at least sixmonths; and, at any time during suchperiods, shall be readily remixedmanually to smooth, uniformconsistency throughout.

The paint shall dry on a road surface toa strongly adherent film that will not turndark in sunlight or show appreciablediscoloration with age. It shall be easilyand uniformly applicable withmechanical line-marking equipment andshall have excellent covering properties.The paint shall be suitable for bindingglass beads so as to produce a highlyweather and wear resistant traffic line.

The composition of the paint suppliedshall conform in all respects to allapplicable state and local air pollutionrequirements including, but not limitedto, the South Coast Air QualityManagement District's Rule 1113, andapplicable rules and regulations fromthe Antelope Valley Air PollutionControl District, regarding ArchitecturalCoatings, regardless of the quantities ofpaints delivered.
