Bituminous Mixtures - Test Methods - Part 48: Interlayer Bonding
Also Known As:
The DIN EN 12697-48 standard provides a set of test methods for evaluating the bond strength between asphalt layers and other newly constructed layers or existing substrates in road or airfield pavements. These tests can also be conducted on interlayers prepared in a laboratory setting.
This standard specifies three normative tests for assessing interlayer bonding: the Torque Bond Test (TBT), the Shear Bond Test (SBT), and the Tensile Adhesion Test (TAT). The TBT is generally applicable to any layer thickness, while the SBT is suitable for layer thicknesses equal to or greater than 15 mm. The TAT, on the other hand, is specifically designed for layer thicknesses below 15 mm.
By providing a framework for these test methods, the DIN EN 12697-48 standard helps ensure the quality and performance of bituminous mixtures used in road and airfield pavements. The results obtained from these tests can be used to assess the strength of the bond between different layers, aiding in the design and construction of durable and reliable pavement structures.
