Influence of Type of Filler and Bitumen on the Mechanical Performance of Asphalt Mortars Tauste Martínez, Raúl García Travé, Gema María Moreno Navarro, Fernando Manuel Rubio Gámez, María Del Carmen Fine aggregate matrix Filler Polymer-modified bitumen Asphalt mortar Asphalt mixture Fatigue performance This article presents a new methodology of analysis based on a fast-running experimental procedure to characterise the mechanical response of asphalt mortars in terms of stiffness, ductility, and fatigue resistance. This was achieved using the DMA (Dynamic Mechanical Analyser) threepoint bending configuration. The study was carried out by considering the employment of different types of fillers such cement and CaCO3 and different types of binders such as conventional asphalt binder (B35/50) or modifided polymer-modified bitumen (PMB 25/55–65). From the results of this study, the filler was found to have a greater influence on the stiffness and ductility of the asphalt material, while bitumen had a higher effect on the fatigue life of the asphalt mortar. Fatigue life was observed to increase with the use of a polymer-modified binder, while a lower degree of permanent deformation and higher bearing capacity achieved by the use of cement instead of calcium carbonate as active fillers. 2022-06-02T06:24:17Z 2022-06-02T06:24:17Z 2022-05-05 journal article Tauste-Martínez, R...
