Abstract:

Because aggregates compose about 95% of the hot mix asphalt (HMA), properties of the aggregates have a significant impact on the performance of HMA pavement. Several specialized aggregate tests, some of which are commonly used in Europe, are evaluated. The tests include methylene blue, Rigden voids index, stiffening power, and dust coating on aggregates. The evaluation was conducted using aggregate sources from 20 projects with known field performance. The methylene blue, dust coating on aggregates, and Rigden voids index or stiffening power, when used with one another, accurately identified aggregate problems in the stripping pavements. The results of this study indicate that if an HMA fails a performance-related test, such as the Hamburg wheel tracking device, these aggregate tests can be used to isolate the potential problematic components of the HMA.
