This paper presents results of laboratory tests on hot and warm bituminous mixtures produced with Reclaimed Asphalt Pavement (RAP). Additives were used to produce warm bituminous mixtures. Fatigue behaviour and thermomechanical behaviour at low temperature were investigated. Fatigue was studied by analysing the tension/compression fatigue test results. Four different failure criteria were used in order to evaluate fatigue life. The low temperature behaviour of the materials was characterized using the Thermal Stress Restrained Specimen Test (TSRST). For each material, three replicates were performed. The experimental device was improved so that radial strains in two directions could be measured during the tests. Tri-dimensional behaviour could thus be investigated. The results of both tests were analysed and the influence of the void content, RAP content, type of additives and manufacturing process was evaluated. The results show that RAP addition and warm bituminous mixtures could be combined to obtain mixtures with performances comparable to classical hot mixtures.

This paper focuses on the influence of the RAP-extracted binder and rejuvenator contents on the steady shear viscosity obtained as a linear viscoelastic property of different binder blends. One pure fresh 50/70 binder, a RAP-extracted binder and a rejuvenator of vegetal origin were mixed in different dosages. Steady shear viscosity (η0) values at different temperatures (from 25 °C to 85 °C) were determined from complex shear modulus results for all tested binders. In addition, η0(T) values of all binder blends were estimated from η0(T) values of base constituents by using two different approaches. Good correspondences with experimental results were found.

The properties of various blends of a fresh binder (50/70 penetration grade) and a RAP-extracted binder, with and without a rejuvenator, were studied. A mixture of vegetal oils was used as rejuvenator in different dosages. A total of 17 binders were tested, including pure fresh and RAP binders. Conventional tests were performed in order to determine penetration at 25 °C, softening point (TR&B), Fraass breaking point (TFraass), ductility (elongation at 25 °C) and density at 25 °C. The steady-shear viscosity (η0) of all binders was calculated from complex modulus test results. Two different approaches were proposed in order to estimate values of penetration, TR&B, TFraass and η0 of blends from properties of base constituents. Excellent correspondences with experimental results were observed.

This paper investigates the effects of reversible phenomena (nonlinearity, self-heating and thixotropy) and damage on bitumen. Four specimens were subjected to different cyclic loading tests: complex shear modulus (G∗), strain amplitude sweeps (SAS) and Loading and Rest Periods (LRP). LRP test consists of applying series of cyclic loading at high strain amplitude (γ0), such as in classical fatigue tests, followed by rest periods (five repetitions). During rest, G* was regularly measured. Specimen temperature was carefully measured during all tests. 2S2P1D rheological model was used along with G∗ tests to characterise linear viscoelastic behaviour, and to calculate the self-heating effect on the measured G∗ during LRP test. SAS results were used to evaluate nonlinearity effect. LRP results showed that temperature may significantly increase during loading. About 5°C increase was observed after 10,000 cycles with γ0= 2%. Such increase results in 70% to 80% modulus decrease, depending on the analysed γ0. Damage was found to cumulate linearly with the total number of applied cycles at fixed γ0, with negligible phase angle variation. After correcting temperature and damage effects, thixotropy evolution could be observed on Black diagrams, where a shared direction with nonlinearity was observed. This suggests a shared intrinsic mechanism, possibly on the microstructural level. Finally, it is clear that reversible phenomena play an important role on the measured G∗, especially at higher γ0. Such effects could not be neglected for the analysed LRP tests (whose loading part is similar to classical fatigue tests). Tests producing less reversible effects should be preferred.

The linear viscoelastic (LVE) behaviour of several combinations of two binders, a straight run 35/50 bitumen and a RAP-extracted bitumen in various proportions (20%, 40% and 60% of RAP binder), was simulated. Two different methods were used to carry out the simulations, The first method consists of a blending rule from the 2S2P1D (2 Springs, 2 Parabolic elements, 1 Dashpot) rheological model, that was calibrated for straight run bitumen and RAP. The second approach is based on the self-consistent model proposed by Hervé and Zaoui [1], considering the two binders as a layered composite sphere embedded in a homogenous medium. Both possible juxtapositions, 35/50 binder over RAP binder (“fresh over RAP”) and vice versa (“RAP over fresh”), were taken into account. All the simulations were compared with 2S2P1D simulations of experimental data obtained from DSR and Tension/Compression tests on samples of perfect blends of the binders, in the same proportions. The two methods yielded different results. Simulations obtained with the blending rule are remarkably close to 2S2P1D simulations of experimental data. “Fresh over RAP” simulations of the self consistent approach are closer than “RAP over fresh” simulations to the results obtained with the blending rule. A statistical analysis was also performed to compare all the considered combinations. Norm (|E*|) and phase angle (φ) of complex modulus at different frequencies (from 1 × 10−6 to 1 × 10100 Hz) and steady state viscosity (calculated from norm of complex viscosity, |η*|, at 1 × 10−100 Hz) were considered as responses. First, a block design approach was used to estimate that significant differences were obtained between all various simulations and 2S2P1D fits of experimental data. Then, the Turkey method was applied in order to compare all combinations with each other and to identify which pairs of combinations show significant differences. The results of the statistical analysis generally confirm the conclusions drawn from the visual judgment of the rheological simulations.

Eiffage developed a high-performance bituminous mixture known as GB5. It is based on aggregate optimization method. This paper presents the results of a research project checking whether, in the small strain domain, this type of mixture behaves like the more conventional asphalt mixture GB3 currently used as a base layer in French bituminous pavements. Three-dimensional complex modulus tests are performed on GB5 and GB3, two hot mixtures asphalt (HMA) made with the same bitumen but produced with different aggregate skeletons. Tension-compression sinusoidal testing is applied to the specimens over a wide frequency and temperature range. Both axial and radial strains are monitored, thereby allowing the computation of the complex Young’s modulus and complex Poisson’s ratios. From the experimental results, the time–temperature superposition principle (TTSP) is verified for both complex Young’s modulus and complex Poisson’s ratios in two directions. The obtained shift factors and normalized complex modulus curves for the two mixtures indicate that the bitumen phase drives the viscoelastic behaviour of the asphalt mixture, regardless of the granular skeleton. The effect of air-void content on the static, glassy, and characteristic time values of modulus and Poisson’s ratios, which is obtained from simulation using a linear viscoelastic model with two springs, two parabolic elements, one dashpot, is analyzed. The anisotropic properties of the two mixtures and the reproducibility between the two laboratories is also checked.

In the presented research, conventional cyclic tension–compression tests and dynamic tests were performed on two types of asphalt mixes (AM). For the tension–compression tests, the complex modulus was obtained from the measurements of the axial stress and axial strain. For the dynamic tests, an automated impact hammer equipped with a load cell and an accelerometer were used to obtain the frequency response functions (FRFs) of the specimens at different temperatures. Two methods were proposed to back-calculate the complex modulus from the FRFs at each temperature: one using the 2S2P1D (two springs, two parabolic elements and one dashpot) model and the other considering a constant complex modulus. Then, a 2S2P1D linear viscoelastic model was calibrated to simulate the global linear viscoelastic behaviour back calculated from each of the proposed methods of analysis for the dynamic tests, and obtained from the tension–compression test results. The two methods of analysis of dynamic tests gave similar results. Calibrations from the tension–compression and dynamic tests also show an overall good agreement. However, the dynamic tests back analysis gave a slightly higher value of the norm of the complex modulus and a lower value of the phase angle compared to the tension–compression test data. This result may be explained by the nonlinearity of AM (strain amplitude is at least 100 times smaller for dynamic tests) and/or by ageing of the materials during the period between the tension–compression and the dynamic tests.

In this paper, conventional cyclic tension-compression tests and dynamic measurements have been applied to three cylindrical specimens of asphalt mixes. The results of the two tests have been compared. For the tension-compression tests, the complex modulus was obtained from the measurements of the axial stress and axial strain. For the dynamic testing, an instrumented impact hammer and an accelerometer have been used to obtain the frequency response functions of the specimens at different temperatures. The dynamic complex modulus was then back calculated by optimizing finite element calculated frequency response functions to match the measured frequency response functions. The 2S2P1D linear viscoelastic model was used to estimate master curves of the complex modulus for the two test methods. The two tests give similar results. However, the dynamic measurements give a higher value of the norm of the complex modulus and a lower value of the phase angle compared to the tension–compression results. This result is probably explained by the nonlinearity of asphalt mixes as dynamic tests are performed at a much smaller strain level than the tension-compression tests.

Recently, the use of geogrids as bituminous pavements reinforcement has increased in pavements construction and rehabilitation, mainly to avoid reflective cracking. One major research topic is to characterize the mechanical behaviour of actual reinforced pavement structures, from laboratory experimentation and take it into account for the design. This paper aims at presenting a methodology for the determination of the Interface Linear Viscoelastic (LVE) behaviour of specimens reinforced with geogrids. This method is based on a tension-compression test on cylindrical sample, classically used for complex modulus tests. A geogrid produced by Texinov was glued with tack coat, which constitute the studied interface. This geogrid is composed by fiberglass filaments and polyester veil, both coated with emulsion. Axial cyclic tests at controlled strain mode of loading (tension-compression) were performed on the same bituminous mixtures samples with and without geogrid. The experimental data was fitted using the 2 Springs, 2 Parabolic Elements and 1 Dashpot (2S2P1D) model both for the mixtures and for the interface. The results indicate that the proposed methodology can successfully provide the interface LVE behaviour.

Highlights•The TSRST test setup was improved to measure radial strain variation during the test.•The repeatability of the TSRST is very good before the failure and reasonable for stress at failure.•The DBN and 3D-2S2P1D were used successfully to simulate the TSRST test in 3D mode.•The thermal cracking resistance remains good for mixes with up to 5% shingles and 15% RAP.•The calibration of the DBN model with 19 calibration parameters gave very good simulation of experimental data. AbstractThe thermo-mechanical behavior of asphalt mixes, with Recycled Asphalt Pavement (RAP) and manufacturing waste roofing asphalt shingles (RAS), is investigated. The cracking behavior at low temperature is studied using the Thermal Stress Restrained Specimen Test (TSRST). The experimental device has been improved with a radial strains measurement system during the performed TSRST. Tri-dimensional behavior could thus be investigated. Studied mixes are made with different RAP contents (up to 25%) and RAS contents (up to 10%). First, the influence of the content of RAP and RAS is analyzed and a ranking of the different mixes is proposed based on the classical TSRST results (stress and temperature at failure). Then, in order to simulate TSRST, a three dimensional modelling is performed with the visco-elasto-plastic DBN model. The calibration steps in the small domain (linear visco-elasticity) and in the large strain domain (non-linearity and visco-plastic flow) are presented. The comparison between experimental and simulated results obtained using the DBN model has shown the potential of the DBN model to simulate the low temperature cracking behavior of asphalt mixes.

Treatment with hydraulic binder is one of the techniques for recycling of reclaimed asphalt pavement (RAP) recovered from road deconstruction. The combined presence of hydraulic binder and bituminous binder (from the RAP) in the mix makes it a composite material, on which the feedback from real road networks is still limited today and which has not yet been considered in the French rational pavement design method (RPDM). The addition of steel fibres in the composite mix allows minimising crack width, solution adopted by the steel fibre-reinforced roller-compacted concrete (FRCC™) technique. FRCC™ mixes with different fibres and RAP contents are compared with another RAP-based material treated with hydraulic binder, ERTALH®. The study discussed in this paper is part of the French National Research Agency project “Recyroute” which aims to evaluate the use of these composite materials in the base layer of heavy traffic roads. Mechanical properties of these composites were investigated by an extensive laboratory test programme. Performance of full-scale pavements was also evaluated throughout an accelerated pavement test (APT). This paper presents the main features and results of the laboratory test programme and the APT experiment as well, leading to propose design parameters of these innovative pavement structures, according to the French RPDM.

Some anisotropic properties in the linear viscoelastic domain of bituminous mixtures compacted with a French LPC wheel compactor are highlighted in this paper. Bituminous mixture is generally considered as isotropic even if the compaction process on road or in laboratory induces anisotropic properties. Tension–compression complex modulus tests have been performed on parallelepipedic specimens in two directions: (i) direction of compactor wheel movement (direction I, which is horizontal) and (ii) direction of compaction (direction II, which is vertical). These tests consist in measuring sinusoidal axial and lateral strains as well as sinusoidal axial stress, when sinusoidal axial loading is applied on the specimen. Different loading frequencies and temperatures are applied. Two complex moduli, \(E_{\mathrm{I}} ^{*}\) and \(E_{\mathrm{II}}^{*}\), and four complex Poisson’s ratios, \(\nu_{\text{II-I}}^{*}\), \(\nu_{\text{III-I}}^{*}\), \(\nu_{\text{I-II}}^{*}\) and \(\nu_{\text{III-II}}^{*}\), were obtained. The vertical direction appears softer than the other ones for the highest frequencies. There are very few differences between the two directions I and II for parameters concerning viscous effects (phase angles \(\varphi(E_{\mathrm{I}})\) and \(\varphi(E_{\mathrm{II}})\), and shift factors). The four Poisson’s ratios reveal anisotropic properties but rheological tensor can be considered as symmetric when considering very similar values obtained for the two measured parameters (I-II and II-I) In addition, an anisotropic 3 dimensional version of the “2S2P1D” (2 springs, 2 parabolic creep elements and 1 dashpot) model, developed at the University of Lyon—ENTPE laboratory, is presented and used to simulate experimental results. The model simulation provides a good fit to the data. Stability of the material could also be investigated on the whole frequency–temperature range.

The objective of the paper is to investigate the influence of bitumen nature on complex modulus and fatigue resistance of bituminous mixtures produced with reclaimed asphalt pavement (RAP). Eight distinct mixtures were produced with eight different modified and unmodified base binders. RAP content was fixed equal to 20% for all mixtures. For each mixture, the corresponding binder blend was produced by mixing the base binder with RAP-extracted binder, in the same proportions. A total of 16 binders (eight base binders and eight binder blends) were therefore used in the study. Both advanced and classical tests commonly used by road paving industry in Europe were performed. Complex modulus (at 15°C and 10 Hz) and fatigue (at 10°C and 25 Hz) DSR tests were carried out on all binders. Two-point bending complex modulus (at 15°C and 10 Hz) and fatigue (at 10°C and 25 Hz) tests were carried out on trapezoidal samples of mixtures. Complex modulus and fatigue resistance of mixtures appeared to vary significantly depending on the nature of the base binder. However, clear correspondences between values obtained for mixtures and corresponding binders could not be found.

Various phenomena other than fatigue (so-called “biasing effects”) occur during laboratory fatigue tests on asphalt mixes because of cyclic loading applications, thus altering experimental results and leading to misleading conclusions. The purpose of the study is to isolate and quantify biasing effects, therefore isolating real fatigue damage. In particular, non-linearity, self-heating and thixotropy (defined as a recoverable viscosity reduction after shear application) were evaluated. Six different mixes were produced using three distinct asphalt binders. Tests were performed in tension/compression mode on cylindrical samples. A particular test procedure was followed, consisting of two parts. In the first part, complex modulus measurements were performed at temperatures from 8°C to 14°C and strain amplitudes from 50 to 110 µm/m, at 10 Hz. Regression equations were fitted in order to evaluate variations of norm of complex modulus and phase angle caused by temperature and strain-level changes around common fatigue test conditions (10°C, 100 µm/m). In the second part of the test, five partial fatigue tests (each one consisting of 100,000 cycles at a 100 µm/m strain amplitude) were performed at 10°C, 10 Hz. After each fatigue lag, a 24 hour rest period was imposed. During rest periods, short complex modulus measurements were performed (10°C, 10 Hz) in order to monitor the recovery of mechanical properties. Surface and internal temperature of samples were constantly measured throughout the entire test, in order to monitor self-heating due to repeated loading. A significant temperature increase was observed during each fatigue lag, while, during rest periods, temperature rapidly decreased to the initial value. Self-heating was observed to be correlated to viscoelastic energy dissipation. The procedure used in the study allowed quantitatively estimating biasing effects. Therefore, unrecovered mechanical properties, due to damage accumulation, were obtained. Ninety per cent of total complex modulus and phase angle variations observed during each fatigue lag were found to be completely reversible. Non-linearity and thixotropy appear to influence mechanical properties variations more importantly than self-heating.

This paper focuses on the three-dimensional (3D) linear viscoelastic (LVE) behavior of bituminous mixtures and the damage occurring after a great number of cyclic loadings. Two complex modulus tests were carried out before and after a fatigue test. The complex modulus E* and complex Poisson’s ratio ν* were measured for large ranges of temperatures (from −25 to 30°C) and frequencies (from 0.03 to 10Hz). First, it is shown that the time temperature superposition principle (TTSP) is verified and applicable in the 3D case. Then, the change of the complex modulus created by fatigue test was analyzed. Lastly, a model with a continuum spectrum called two springs, two parabolic elements, one dashpot (2S2P1D), developed at the Ecole Nationale des Travaux Publics de l’Etat (ENTPE), was used to simulate the 3D linear viscoelastic behavior of the tested bituminous mixture before and after fatigue damage.

This paper presents results of laboratory tests on nine types of specimens consisting of different hot and warm mix asphalts produced with a reclaimed asphalt pavement. Linear viscoelastic behaviour was investigated using tension–compression tests on cylindrical specimens on a wide range of temperatures (from −25°C to +45°C) and frequencies (from 0.03 to 10 Hz). Complex moduli, E*, and complex Poisson's ratios, ν*, were determined in two perpendicular material directions. Differences between measured ν* reveal a negligible anisotropy in the horizontal confection plane. The time–temperature superposition principle was verified with good approximation, with the same shift factor values, in one-dimensional and three-dimensional conditions. The same values of shift factor were also obtained for all specimens that contain bitumen with identical crude oil origin. Experimental results were modelled using the 2S2P1D model previously developed at the University of Lyon/ENTPE. In this paper, a new representation of results using normalised curves is proposed. These curves show identical properties for the different materials, which have the same origin of bitumen and aggregate. Finally, the performance of tested materials was compared.

This paper presents the results of laboratory testing of hot and warm bituminous mixtures containing Reclaimed Asphalt Pavement (RAP). Complex modulus measurements, using the tension–compression test on cylindrical specimens, were conducted to determine linear viscoelastic (LVE) behavior. Sinusoidal cyclic loadings, with strain amplitude of approximately 50⋅10−6, were applied at several temperatures (from −25 to +45 °C) and frequencies (from 0.03 Hz to 10 Hz). In addition to axial stresses and strains, radial strains were also measured. The complex modulus E ∗ and complex Poisson’s ratios ν ∗ were then obtained in two perpendicular directions. Measured values in these two directions do not indicate anisotropy on Poisson’s ratio. The time-temperature superposition principle (TTSP) was verified with good approximation in one-dimensional (1D) and three-dimensional (3D) conditions for the same values of shift factor. Experimental results were modeled using the 2S2P1D model previously developed at the University of Lyon/ENTPE. In addition, specific analysis showed that eventual damage created during complex modulus test is very small and is equivalent to the effect of an increase of temperature of about 0.25 °C.
