Bituminous mixtures - Test methods - Part 26: Stiffness
Also Known As:
The DIN EN 12697-26 standard defines methods for evaluating the stiffness of bituminous mixtures. These methods involve various types of tests, such as bending tests, direct tensile tests, and indirect tensile tests. The tests are conducted on compacted bituminous material under controlled loading conditions, typically employing sinusoidal loading.
The primary purpose of these tests is to assess the relative stiffness of different bituminous mixtures, providing guidance on their performance in pavement applications. The results obtained from these tests are also used to estimate the structural behavior of the material in road construction and to verify compliance with specifications for bituminous mixtures.
This standard does not prescribe a specific testing device, allowing for flexibility in selecting the appropriate test conditions based on the capabilities of the chosen equipment. However, the requirements specified in the product standards for bituminous mixtures should be considered when determining the specific test conditions. The applicability of this standard is further defined in the relevant product standards for bituminous mixtures.
