Influence of warm mix additives on the low-temperature behavior of bitumen using the Bending Beam Rheometer (BBR)

The mechanical and rheological characteristics of bitumen are crucial for the behavior durability bituminous road layers. A susceptible to high temperatures can lead plastic deformation layers, whereas a low temperature binder cracking penetration test at 25 °C, softening point - ring ball method ductility were carried out on 50/70 five types blends. In order determine temperatures, Bending Beam Rheometer was implemented. presented research aims how different additives that have purpose increase workability asphalt mixtures (for making warm mix asphalts) influence commonly used in Romanian technique. this regard, results regarding susceptibility presented, compared those same which various introduced. To further highlight bitumen, is completed by tests mastic each type binder. do not significant changes rheology pure bitumen. wax has biggest bitumen‘s properties. limit increases with addition filler
