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).

This document describes a test method for the determination of the water content of samples of bituminous mixtures. The test method is suitable for checking conformity to a product specification, where required. Exposure levels are related to both handling procedures and ventilation provision and it is emphasized that adequate training should be given to staff employed in the usage of these substances.
