Characterization of Dense-Graded Asphalt With the Cantabro Test



Durability of dense-graded asphalt (DGA) is a key issue with regards to long term pavement performance. There is a need for a practical and implementable test to estimate these parameters. Previous research has suggested that the Cantabro abrasion loss test has potential for this application. Both the development of the Cantabro method and its conventional application to open-graded friction course (OGFC) mixtures are reviewed. A four component research approach was undertaken to evaluate suitability of the Cantabro test for DGA mixtures that included testing of 438 specimens from 69 different mixtures. First, sensitivity of the test was assessed using a large range of typical Mississippi DGA mixtures. Second, variability of the test was measured by evaluating data sets with thirty replicates. Third, the effects of oven conditioning protocols were measured. Fourth, the effects of varying reclaimed asphalt pavement (RAP) contents were measured for warm-mix asphalt (WMA). The overall recommendation from the research was that the Cantabro test be given serious consideration for use as a durability measurement tool for DGA mixtures.
