ČSN EN 12697-12   (736160) Asfaltové směsi - Zkušební metody pro asfaltové směsi za horka - Část 12: Stanovení odolnosti zkušebního tělesa vůči vodě

Anotace textu normy ČSN EN 12697-12   (736160)

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 anti-stripping additives including liquids, such as amines, and fillers, such as hydrated lime or cement.
