This document specifies test methods for determining the bond strength between an asphalt layer and other newly constructed construction layers or existing substrates in road or airfield pavements. The tests can also be applied on laboratory prepared interlayers. The normative tests described in this document are: — Torque Bond Test (TBT), generally applicable to any layer thicknesses; — Shear Bond Test (SBT), generally applicable to layer thicknesses > 15 mm; — Tensile Adhesion Test (TAT), generally applicable to layer thicknesses ≤ 15 mm. NOTE Further non normative test methods are described in informative annexes: — Annex A (informative) - Compressed Shear Bond Test (CSBT); — Annex B (informative) - Alternative Shear Bond Test (ASBT); — Annex C (informative) - Layer Adhesion Measuring Instrument (LAMI).
