scope:

This draft European Standard specifies test methods for determining the bond strength between an asphalt layer and other construction layers in road or airfield pavement. The tests can also be applied on laboratory prepared interlayers. Further informative test methods are defined for evaluating the complex bond stiffness between road construction layers. The normative tests described in this standard are - Torque bond test (TBT), - Shear bond test (SBT), - Tensile Adhesion Test (TAT). Further two test methods for evaluating the complex bond stiffness are described in informative annexes: - Compressed shear bond test (CSBT), - Cyclic compressed shear bond test (CCSBT).
