【国外标准】 Standard Test Method for Laboratory Determination of Degree of Bleeding of Traffic Paint (Withdrawn 2010)

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 test method describes how to prepare a panel for evaluation. The very subjective method of evaluating the degree of bleeding raises questions as to the usefulness of the result for specification compliance.1.1 This test method covers a laboratory test procedure for determining the degree of bleeding of traffic or pavement marking paints.1.2 The values stated in inch-pound 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.
