ABSTRACT

ABSTRACT: In this paper two different methodologies of fatigue testing as used in the Czech Republic have been compared. Fatigue tests on selected Asphalt Concrete mixtures (AC) have been done using by two Point Bending (2PB) and four Point Bending tests (4PB) using trapezoidal and prismatic beams respectively. The methodologies of the above stated tests are known for several years. The fatigue characteristics of experimental asphalt mixes have been compared. However, the interpretation of the test results according to the EN 12697-24 standard is according to Czech experience still not completely clear. The paper takes over the results from the 2nd Workshop on Four Point Bending, which took place in Portugal, where stiffness modules were compared on the same mixes.
