DIRECT TENSION TEST RESULTS FOR SOME ASPHALT CONCRETES

Several thickness design and analysis techniques that have recently been made available utilize tensile strain as part of the procedure. A study was undertaken to determine the effect of some mixture and environmental variables on strain at failure (limiting strain) for some asphalt concretes. Cylindrical specimens were loaded to failure in direct tension and strain at failure was calculated from axial deformations. The information can be used to establish working values for rational mixture and thickness designs for mixtures where experimental and field parameters are essentially the same. These fundamental data can also be used to correlate direct tension values with those that are obtained with simpler indirect tension test methods.
