Historical (view previous versions of standard)
Significance and Use
Solvents in a traffic paint may cause bleeding of pavement constituents into the traffic marking, thereby rendering the traffic marking less effective as a lane or directional indicator. This practice describes how to prepare a panel of the coating to be tested and a reference panel coated with a specific solventborne traffic paint to be used as a control for evaluation.
This practice can be particularly useful for evaluation of solventborne traffic paints, but it may also be used for other types of traffic markings including waterborne traffic paints.
Two basic procedures are described for measuring the amount of bleeding. The procedure used shall be agreed upon by the purchaser and seller.
1.1 This practice describes test procedures for determining the degree of bleeding of traffic or pavement marking paints. A specific formulation for a solventborne traffic paint formulation is included as a potential bleeding reference control
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
