“…It is known that a filler with a higher surface area enlarges the interaction between the filler and the bitumen (Jiménez, Recasens, & Martínez, 2008;. Also, fillers that are embedded inside the bitumen can absorb part of the bitumen and form an absorbed layer on the outside of the particle, changing thus locally the flow properties of the bitumen (Hesami, Jelagin, Kringos, & Birgisson, 2012).…”

In this contribution the development and results of a new test protocol for measuring the viscosity of bituminous mastics are presented. The paper describes the various considerations that need to be taken into account when dealing with mastics, gives a detailed description of the sample preparation, the test set-up and the actual test performance. A demonstration of the use of the test procedure is given by developing three types of mastics in which different filler types, but a similar bitumen base, were used. From the results it can be seen that the developed protocol is sensitive enough to allow for detailed studies of the effect of filler shape, chemistry and size distribution. In continuation of this work, more types of mastics will be investigated and the test results will be linked to additional chemical and mechanical test results to further enhance the fundamental understanding of mastics.

“…It is widely recognised that the fatigue resistance of bituminous mixtures employed in the construction of flexible pavements is strongly influenced by rheological properties of the binder phase (Soenen et al 2003;Boussad et al 1996). In particular, mixture performance is closely controlled by the binder-filler mastic as a consequence of the aptitude of the finest portion of the aggregate skeleton to alter the rheological behaviour of base bitumen (Faheem and Bahia 2010;Pérez Jiménez et al 2008).…”

The research work described in the paper focused on fatigue and healing properties of bituminous mastics reinforced with nano-sized additives.Commercially available multiwall carbon nanotubes (CNTs) and montmorillonite nanoclay (NC) were combined with a single base bitumen and a standard mineral filler to produce bituminous mastics. These blends were prepared in the laboratory by making use of a technique consisting in simple shear mixing followed by sonication.Fatigue behaviour of mastics under repeated loading was investigated by means of time sweeps performed in the strain-controlled mode at various amplitudes. Healing potential was assessed by adopting a testing protocol specifically conceived to discriminate between recovery of damage induced by fatigue loading and other artefact phenomena which may affect material response. All rheological measurements were carried out with a dynamic shear rheometer in the parallel plates geometry.Outcomes of the experimental investigation were found to be highly dependent on the nature of additive type, as a result of the key role played by interaction mechanisms that nano-particles can establish within the bituminous mastic.

“…The UCL method can also be used to evaluate the filler effect of bituminous mastics (Pérez Jiménez et al, 2008). The filler is an essential element of the bituminous mixtures because it is the mixture component which is most intimated mixed with the binder, modifying both its rehology and its behavior.…”

ABSTRACT. The aim of this paper is to study the influence of crumb rubber on the improvement of cohesion provided by bitumen. The UCL Method is a procedure for binder characterization based on the evaluation of the degree of cohesion provided by a set amount of binder to an aggregate of a set grading (standard mixture). This method can be used to evaluate both, the dry and the wet adding procedures. The results obtained show that the wet procedure presents clear advantages over the dry procedure with and without digestion, especially when the binders are manufactured by microscopic dispersion.
