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: \u2014 Torque Bond Test (TBT), generally applicable to any layer thicknesses; \u2014 Shear Bond Test (SBT), generally applicable to layer thicknesses > 15 mm; \u2014 Tensile Adhesion Test (TAT), generally applicable to layer thicknesses \u2264 15 mm. NOTE Further non normative test methods are described in informative annexes: \u2014 Annex A (informative) – Compressed Shear Bond Test (CSBT); \u2014 Annex B (informative) – Alternative Shear Bond Test (ASBT); \u2014 Annex C (informative) – Layer Adhesion Measuring Instrument (LAMI).<\/p>\n
