Bituminous mixtures - Test methods - Part 12: Determination of the water sensitivity of bituminous specimens
|Publication Date:||1 June 2018|
|ICS Code (Road construction materials):||93.080.20|
This European Standard 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 antistripping additives including liquids, such as amines; and fillers, such as hydrated lime or cement.
