Influence of limestone filler on the rheological properties of bituminous mastics through susceptibility master curves

An experimental laboratory study of fiber-reinforced asphalt mortars with polyolefin-aramid and polyacrylonitrile fibers

“…It is worth mentioning that asphalt mortar only contains filler and fine aggregates with maximum particle size of 2 mm. These particles have greater surface area than coarse aggregates and hence it is necessary to increase the binder content in the mix to ensure the same aggregate binder film thickness [44,45]. The second fiber used was polyacrylonitrile fiber (PAN).…”

Rheology of Polymer Processing in Spain (1995–2020)

“…On the other hand, the effect of inorganic filler concentration, composition, and size distribution on the rheology of bituminous mastics has been studied, where continuous phase may be either a neat bitumen or a polymer-modified binder. In this respect, Lagos-Varas et al [ 177 ] found that the filler increases the rigidity of the mastic at all temperatures and frequencies tested, but the observed increase depends on the type of bitumen used. For LDPE-modified bituminous mastics, Roman et al [ 178 ] found enhanced complex shear modulus and elasticity at high in-service temperature.…”

Study of the permanent deformation of binders and asphalt mixtures using rheological models of fractional viscoelasticity

“…In this way, all deformation states of the asphalt binder can be explained, reducing the number of rheological variables involved in curve settings. The use of fractional exponents (α and ) allows the elastic-viscous transition of the binders to established, since they are not considered Newtonian fluids at a temperature of 20°C [3]. The differential equation (Eq.…”

“…However, the increase in vehicle traffic and tremendous climatic variations have caused permanent damage to the asphalt layers along the path of the wheels, resulting in traffic accidents due to the poor quality and comfort of driving [2]. The asphalt binder is a petroleum-based product that has little elastic capacity when subjected to different stresses, generating plastic deformations due to its anelastic nature [3]. Therefore, in recent decades, the rheological study of this material has generated great scientific discussions and comparisons on its mechanical behaviour in the asphalt mix.…”
