The test method makes it possible to determine the minimum binder content of the slurry seal mixtures during formulation from the abrasion behavior in the presence of water. The abrasion is produced by a rubber cylinder which describes a planetary rotation movement. Different mixtures, varying in their binder content, are subjected to the test, after which the loss of mass by abrasion is measured.
The abrasion lasts 5 minutes on the surface of the sample previously prepared, cured in an oven and moistened by immersion. The test determines the minimum amount of emulsion to resist traffic abrasion.
