Cracking has become the primary asphalt pavement distress in Arkansas. Arkansas along with other states have implemented a test to measure rutting resistance. This paper presents research to implement a cracking resistance test to further modify the Superpave volumetric asphalt mixture design method in Arkansas. The Illinois Flexibility Index Test (I-FIT) was the test chosen to analyze for this research. Two aging methods were tested, a short term oven aging (AASHTO R30 ST) and a long term oven aging (NCAT) method. Six asphalt mixtures were selected to be tested. The mixtures testes were recreated from Arkansas Department of Transportation (ARDOT) …
