“…As expected, the bitumen has a greater resistance than the mastics because of the lower stiffness and greater ductility, and their behaviour is strongly affected by the temperature. It was shown before that the strain amplitude at the failure of specimens in the EBADE test decreases with their stiffness [11]. Under straincontrolled conditions, the stiffer materials are subjected to higher stresses than the softer materials for the same imposed strain amplitude.…”

“…The highest temperature targets the soft viscoelastic and ductile regime, and the lowest temperature targets the stiff and brittle regime. The discussion of these results to evaluate the effect of ageing and filler on the behaviour of the bitumen was previously reported in [11].…”

“…The objective of this study was to make a critical analysis of the interpretation of cyclic strain sweep test results, relating the observed changes in test quantities with the physical mechanisms determining the material's behaviour upon loading at different temperatures, and to discuss different methods and approaches to define the fatigue resistance. For this purpose, we used the experimental data of a cyclic tension-compression strain sweep test (EBADE test protocol) collected in a previous investigation to analyse the ageing effect on the fatigue behaviour of bitumen and mastics [11]. The EBADE (acronym of Ensayo de BArrido de DEformaciones) is a procedure developed at the Technical University of Catalonia (Spain) for the evaluation of the fatigue resistance of bituminous materials [7].…”

This paper discusses the analysis of uniaxial tension-compression cyclic strain sweep test results for the characterisation of bituminous materials. The test results of one bitumen and two mastics, at different oxidative ageing levels, at three different temperatures are used in the study. The damage mechanisms leading to failure were shown to vary with the temperature, and the transition from slow to fast damage accumulation could be clearly seen in the evolution plots of different mechanical variables with loading cycles. It was shown that the plot of test results in the Black diagram provides an excellent viewpoint for the damage and non-damage related mechanisms affecting the material's response to increasing loading amplitude. Before significant damage has accumulated in the specimen, the stiffness modulusphase angle curve, at different temperatures, follows very closely the linear viscoelastic curve of the undamaged material, and heating was identified as the most important reversible mechanism. The thixotropic effect was clearly observed in mastics. The curve shape during fast progression to failure was related to the level of deformation around the crack zone. The slope of the stiffness modulus-phase angle curve was found to provide a consistent indicator of the material's resistance to cumulative loading, as it is sensitive to the material's ageing state and the test temperature, and a unique relationship between this factor and the number of cycles to failure was found for all materials and test conditions.

“…The LAS test is a commonly used method to evaluate the (shear) fatigue behaviour of asphalt binders; it differs from the time sweep test because the load amplitude is increased throughout the process. For this reason, the LAS test takes less time and fewer samples are needed [81,82]. Regardless of the loading mode adopted, it is acknowledged that the cohesive failure of the disk-shaped specimen occurs due to the progression of radial microcracks from the outer edge towards the centre of the specimen.…”

Biomass is one the most abundant renewable energy sources, and it can be processed through different thermochemical methods to obtain oils that can replace the petroleum bitumen used in road construction. For the construction industry to accept the bitumen replacement with bio-oil, it is necessary to know its properties and determine the applicability of conventional testing methods. This research utilized a liquified wood heavy fraction (bio-oil) obtained from waste wood through an innovative thermochemical liquefaction process. The aim was to investigate a kind of bio-bitumen produced by blending this bio-oil with paving-grade bitumen. The rheological behaviour in a wide temperature range, the performance relative to fatigue cracking and permanent deformation sensitivity, and the evolution with oxidative ageing were evaluated for the bio-bitumen and paving-grade bitumens. The bio-oil significantly affected the rheological behaviour of bitumen through an overall decrease in the phase angle and by failing the time–temperature superposition principle. The strong elastic response of the bio-bitumen improved resistance to fatigue and permanent deformation accumulation; however, resistance to oxidative ageing declined. Linear viscoelastic rheological indicators proposed in the literature to assess the material’s performance showed a similar trend of variation with oxidative ageing for bio-bitumen and paving-grade bitumen, though the indicators’ values could not be directly compared.
