Effect of Flat and Elongated Coarse Aggregate on Characteristics of Gyratory Compacted Samples
This report presents findings on the effect of flat and elongated coarse aggregate particles on the volumetrics of Superpave Gyratory Compactor (SGC) prepared asphalt mixtures. Select aggregate sources were sampled to provide aggregate with varying levels of flat and elongated particles. The particles were hand separated and classified according to the flat and elongated ratio. Mixtures with specific gradations were assembled using the gravel and dolomite aggregates with controlled percentages of 3 to 1 and 5 to 1 particle shapes. Changes in the gradations of the compacted mixtures were noted and related to initial particle shapes and amounts and the aggregate source. No significant impact on mixture volumetrics could be assigned to the presence of flat and elongated particles.
