This document defines three procedures to evaluate the compatibility of the constituent materials of a bituminous mixture with bitumen emulsion. These organoleptic methods can be used together to evaluate the compatibility of the constituent materials after a hand mixing procedure for given emulsion and water content: - Method A describes a test method to determine visually the degree of coating; - Method B describes a test method to determine the consistency; - Method C describes a test method to determine the hydric aspect. This document applies to mixtures prepared in the laboratory or taken from the plant.
