Four Point Bending beam tests (4PB) were conducted on asphalt (bituminous) hot mixes placed on Arizona Department of Transportation (ADOT) test projects. The evaluated mixes were constructed over a wide range of climate zones and traffic loadings. The 4PB tests were primarily conducted byArizona State University for theADOT.The tested hot mixes included dense graded, gap graded and open graded. In addition various asphalt binders were evaluated including several different performance graded asphalts and asphalt rubber. This paper evaluates the results of the 4PB tests in terms of the asphalt content, air voids and the asphalt binder properties, as well as the viscosity temperature intercept and slope values, A and VTS, in terms of the long term field cracking performance.
