ASTM D969 "Determination of the bleeding degree of road marking paint in the laboratory" specifies the standard method for measuring the bleeding degree of road marking paint in the laboratory. The standard specifies the preparation requirements of the sample, specifies the test procedure for coating the road marking paint on a specific substrate and contacting the material that may cause bleeding. By setting the observation time, temperature and other conditions, the bleeding phenomenon is graded and evaluated, providing a unified detection standard for accurately determining the bleeding performance of the road marking paint, ensuring the mass of the road marking paint and the application effect.
