This document specifies three test methods for determining the effect of saturation and accelerated water conditioning: - method A uses the indirect tensile strength of cylindrical specimens of bituminous mixtures; - method B uses the compression strength of cylindrical specimens of bituminous mixtures; - method C defines the bonding value for a bituminous mixture 1 h after mixing, where the bonding of bitumen and aggregate can be equated to a bonding value. Method C is suitable for soft asphalt with bitumen of kinematic viscosity at 60 °C of 4 000 mm2/s or less. These methods can be used to evaluate the effect of water on asphalt mixtures with or without anti-stripping additives including liquids, such as amines; and fillers, such as hydrated lime or cement.

This document describes a test method for the determination of the water content of samples of bituminous mixtures. The test method is suitable for checking conformity to a product specification, where required. Exposure levels are related to both handling procedures and ventilation provision and it is emphasized that adequate training should be given to staff employed in the usage of these substances.

This document specifies a framework of additional characteristics and associated test methods for bitumens and bituminous binders, which is complementary to other product standards for bitumens and bituminous binders. This document is applicable to bitumens and bituminous binders suitable for use in paving applications, but it is also applicable for other uses such as waterproofing membranes. With regard to paving applications, the following characteristics are addressed: - resistance to permanent deformation (rutting); - resistance to low-temperature cracking; - resistance to ravelling; - resistance to fatigue cracking; - temperature susceptibility; - equi-stiffness temperature and phase angle; - durability (evolution of equi-stiffness temperature and phase angle); - mixing and handling characteristics (paving and compaction) temperatures; - additional characteristics (e.g. solubility, elastic recovery and storage stability). Not all the properties and characteristics established in the framework are universally relevant to all binders. For example, elastic recovery is not relevant for unmodified binders.
