Caracterización reológica avanzada de betunes tradicionales y modificados utilizados actualmente en Chile Advanced rheological characterization of traditional and modified bitumens currently employed in Chile

The purpose of this research was to achieve an advanced rheological characterization and classification for a set of modified and non-modified asphaltic bitumens currently employed in Chile. Six asphaltic bitumens were employed, which are locally produced by three asphalt manufacturer companies. Each company provided a traditional bitumen and a modified bitumen. The three traditional bitumens were classified as CA 24 and, SBS-modified bitumens were classified as 60-80. Rheological characterization tests were carried out by employing a dynamic shear rheometer and a bending beam rheometer on bitumens under original condition; primary
