As part of RILEM TC 237-SIB, TG3 performed a Round Robin Test to evaluate the capacity to measure Poisson's ratio of an asphalt mixture in the laboratory and to check whether it could be considered as an isotropic property. Five laboratories located in five different countries took part in the testing program. This paper presents the different techniques used by the laboratories, reports the measured Poisson's ratios and comments upon the differences found between the results. Sinusoidal or haversine loading either in tension-compression or pure compression was applied to the specimens over a range of frequencies and temperatures. During the loading both the axial and radial strains were monitored to allow the complex Young's modulus and the complex Poisson's ratios to be calculated. It was found that the complex Young's modulus and the complex Poisson's ratios were very close in the Black Diagrams, but diverge sharply in the Cole-Cole plots. It was observed that the maximum difference between the complex Poisson's ratio in direction 2 and direction 3 is less than 0.05. It would appear that this difference is more related to measurement deviation than anisotropy of the material. Some differences were observed in the master curves of complex Young's modulus and complex Poisson's ratio obtained from the five laboratories; however these differences could in most cases be explained by temperature differences. It was concluded that within the linear viscoelastic range (small strains) the results from the different laboratories show similar rheological behavior and the material response follows the same trend.

In Québec, for more than 20 years, cold in-place recycling (CIR) and full-depth reclamation (FDR) have been reliable rehabilitation techniques; restoring pavement condition at an affordable cost with a lower footprint on the environment. Experience reveals that CIR and FDR interventions effectively address the issues of reflective cracking and respect Québec's Ministry of transportation rutting threshold values. However, despite their commendable performance in the field, the cold recycled emulsified asphalt materials (CRM) has yet to be adequately characterized with respect to their rheological properties. This study was undertaken to evaluate the rheological behavior of the CRM with four different combinations of RAP (50, 75, 85, and 100%). The scope of work for this study consisted of preparing the laboratory compacted CRM specimens, determining the complex modulus (E*) of compacted specimens at various testing temperatures and loading frequencies, analyzing the experimental data with the help of 2S2P1D (2S: two springs, 2P: two parabolic elements, 1D: one dashpot) model and finally, validating the results with pavement design. It was concluded that 100% RAP mixture exhibits extremely high stiffness value at high frequency and low temperature. The results revealed that all four mixtures respect the time-temperature superposition principle with respect to the complex modulus. From a pavement design perspective, the moduli measured in this study do have a big impact. However, since different pavement structure are achieved with those different materials, the stiffest material, the CIR, ended up giving the least performant structure.

“…Among currently used mechanistic models for rheological changes in bituminous mixtures, the generalized Huet-Sayegh model referred to as 2S2P1D can be successfully applied for establishing the master curve (Yusoff et al 2013). The model, calibrated by the Ecole Nationale des Travaux Publics de l'Etat (ENTPE), is capable of providing correct characterization of the behaviour of bitumen and bituminous mixtures (Olard, Di Benedetto 2003).…”

Abstract. The article presents the results of dynamic modulus tests carried on the asphalt concrete (AC16W). The sinusoidal load was applied to the samples in accordance with DTC-CY method. The neat bituminous binder (penetration grade 35/50) was modified by means two synthetic waxes, coming from the Fischer-Tropsch raction, with various molecular weights and softening point temperature results (hard and softer). The relaxation phenomenon in terms of changes in complex modulus and phase angle was evaluated using the modified Huet-Sayegh (2S2P1D). Estimated model parameters pointed out that the addition of the synthetic wax with the high (hard wax) and the low (softer wax) molecular weight raised the stiffness of the bituminous binder in relation to the reference bitumen 35/50. The application of the modified Huet-Sayegh model showed that the presence of the synthetic wax in the bitumen significantly affected the stiffness modulus of considered asphalt concretes. Basing analysis on Cole-Cole diagram it was found significant differences in the viscoelastic behaviour between the reference asphalt concrete and the asphalt concretes with synthetic waxes. In contrast, there were no significant differences between viscoelastic properties of tested asphalt concretes modified, used in the experiment, synthetic waxes. Furthermore, the sensitivity to the loading time of asphalt concretes containing both synthetic waxes was marginal.
