Stiffness Comparison of Asphalt Concrete Containing Reclaimed Asphalt Using Various Test Methods – 4-point Bending Test and Indirect Tensile Test
As part of ongoing research study two different methodologies of stiffness determination have been compared. Stiffness tests on a selection of Asphalt Concrete mixtures (AC) containing various contents of reclaimed asphalt have been performed using the indirect tensile test on cylindrical specimen with pulse load form (IT-CY) and 4-point bending test with prismatic specimens (4PB-PR). The determining aim presented by this paper was to compare interdependency of resulting stiffness values from both test methods. The above-mentioned test methodologies are commonly used for many years. A total of 56 mixtures was manufactured and tested. The evaluated samples covered asphalt mixtures containing varying content of reclaimed asphalt as are used in the Czech Republic in all pavement layers. The group was further divided according to used bituminous binder (non-modified vs. modified) and reclaimed asphalt content.
