“…The E* value ratio increased with the PAV conditioning time and the test temperature, although the bitumen was no more affected than the mastics. These results do not agree with the previous analysis of these materials [19], which showed smaller shear modulus (G*) value ratios obtained at 20ºC for the mastics (especially with BF2). However, it should be emphasised that the differences in E* value ratios among the tested materials are not large (except for BF2-25h at 17.5 ºC)…”

“…In this study a paving grade bitumen, grade 50/70 [18], was used with a needle penetration at 25ºC of 49·10 -1 mm and a softening point of 48.2 ºC. Before, in [19], good ageing resistance was reported for this bitumen due to its balanced chemical composition. The bituminous mastics were fabricated with this bitumen and two different mineral fillers.…”

“…To complement the analysis of the ageing effect on cyclic loading behaviour, Figure 7 plots the results of the linear amplitude sweep (LAS) test performed previously with these materials (unaged and aged 25 h) at 25ºC and reported in [19]. The LAS is a strain sweep test protocol implemented in the dynamic shear rheometer that was developed for the evaluation of the fatigue performance of binders [29].…”

“…Also, the increase in stiffness is more noticeable in the low frequency range. These results obtained under tension-compression loading agree in general with the conclusions reported in similar studies that adopted a shear-loading setup [38,39]. For the first ε i value (0.076%), σ i is mostly nearly constant, and the same trend occurs with the other mechanical variables.…”

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.

“…Numerous researchers have utilised intermediate materials, for example, mastics, i.e. mixes of just bitumen and filler, as a model framework [11][12][13]. The thought behind this methodology is that the material sticking together the aggregates inside the mixture is not the bitumen only but is the bitumen mixed with the finest components of the mineral aggregate, called 'filler' [14].…”

In asphalt mixture, a strong affinity between binder and aggregates is of prime importance, especially under conditions susceptible for moisture damage. To improve this affinity between binder and aggregates various additives and modifiers have been identified by the researchers across the globe. Among all the available additives or modifiers, hydrated lime has been reported as one of the best, which can be used to enhance the affinity between bitumen and aggregates. This study attempts to quantify the affinity of hydrated lime modified mastics with different aggregates under moisture conditions. Various techniques are available for the affinity assessment between binder and aggregates, with the rolling bottle test (RBT) reported as one of the best empirical techniques which is used worldwide.In the RBT test the assessment for affinity is made through visual inspection by two experienced operators as per a standard procedure which can also be the major drawback of this technique. An effort has been made to reduce this deficiency in the method and to make the RBT a more reliable and repeatable means of measuring the affinity between aggregate and binder in the presence of water. This has been done using image analysis techniques with no special setup, employing the Matlab program. The results after image analysis were compared to the results of visual observation and both were found to be very similar to each other. Hence the RBT can now be used confidently for the comparison of different binder/aggregate combinations. The beneficial effects of HL addition were clearly quantified with granite, basalt and greywacke aggregates, but limestone aggregates did not respond to the effect of HL addition when tested in the RBT. Based on the results of the RBT test, 10% HL substitution was found to be more efficient than a 20% HL substitution, which gave very similar results to 10% HL substitution in most of the studied combinations.
