Bituminous Mixtures - Test Methods - Part 48: Interlayer Bonding
Also Known As:
The DIN EN 12697-48 standard outlines the procedures for assessing the bond strength between asphalt layers and other construction layers or existing substrates in road or airfield pavements. This standard applies to both field and laboratory testing.
The standard includes three normative tests for determining the bond strength: the Torque Bond Test (TBT), the Shear Bond Test (SBT), and the Tensile Adhesion Test (TAT). The TBT is generally applicable to any layer thicknesses, while the SBT is suitable for layer thicknesses exceeding 15 mm. On the other hand, the TAT is specifically designed for layer thicknesses of 15 mm or less.
These tests help evaluate the quality of the bond between asphalt layers and other layers or substrates, ensuring that they are adequately bonded to each other. These test methods provide valuable information for the construction and maintenance of road and airfield pavements, ultimately contributing to their durability and performance.
