Investigation of rutting potential of Open Graded Friction Course (OGFC) mixes using asphalt pavement analyzer
Abstract This study presents a laboratory evaluation on rutting resistance of Open Graded Friction Course (OGFC) mixes made with different polymer modifiers and coarse aggregate sizes. For this research work, six mix designs for three polymer modifiers (3% SBS modified, 6% LDPE modified, and 12% rubber modified) and two aggregate sizes (13 mm and 10 mm) were carried out to determine the optimum asphalt contents. The OGFC specimens were fabricated using the Superpave gyratory compactor at a compaction level of 50 gyrations. The air void contents and final rut depths of the mixtures were measured by the Corelok system and the Asphalt Pavement Analyzer (APA), respectively. In general, the results indicated that the polymer modifier plays an important role in the rutting resistance of the OGFC mixes used in this study. With respect to the coarse aggregate size, it was found to have little effect on the rutting potential.
