“…Rutting is one of the major stressors of asphalt pavements, caused by high temperature and high traffic loading. According to Singh et al [42], higher values of the rutting parameter indicate better rutting resistance. Figure 6 shows the trend of the rutting parameter as a function of three different temperatures, chosen in accordance with the literature [43][44][45].…”

In recent times, circular economy initiatives in addition to the need for sustainable biomaterials have brought about several attempts at the eco-friendly, eco-sustainable and cost-effective production of asphalt pavements. It is an increasingly common practice in the asphalt industry to improve road pavement performance using additives to enhance the physico-chemical properties of bitumen, which performs the role of the binder in the asphalt mix. This paper evaluated the potential of a bio-based additive derived from olive leaf residue as a modifier and antioxidant agent for bitumen. Samples of neat, aged and doped aged bitumen were analyzed. In this study, the two bio-based additives were characterized in terms of phenol, chlorophyll, lignin and cellulose content, which was correlated with the mechanical properties of the tested samples. The mechanical properties of the neat, modified, aged and unaged samples were evaluated via Dynamic Shear Rheology. The bio-based additives proved to be promising and can improve the properties of bitumen binder and the performance of asphalt pavements in general.

“…Over the years, conventional/basic test methods including penetration, softening point, and Saybolt-Furol viscosity have been explored to characterize and quantify the hightemperature rheological characteristics of asphalt-binders relative to HMA rutting performance [15][16][17][18][19][20][21][22][23]. Although relatively simple to perform, these tests are empirical in nature and not directly performance related [19,23]. From a technical perspective, these shortcomings can be attributed to: (a) the use of a single test temperature, (b) the specimen loading condition, (c) the high variability among test results, (d) the inability to reasonably characterize the asphalt-binder with respect to the mix rutting resistance and overall pavement performance, and (e) the unreliability to adopt for new generation materials such as modified asphalt-binders [18][19][20][23][24][25].…”

Asphalt-binder is one of the key constitutive components of hot-mix asphalt (HMA) that considerably affects its rutting performance. In particular, the high-temperature rheological properties measured from the Multiple Stress Creep and Recovery (MSCR) test are critical in quantifying the HMA rutting resistance. In this study, the Texas flexible pavements and overlays database (the Texas Data Storage System [DSS]) was used as the data source to investigate the effect of asphalt-binder high-temperature rheological properties on the HMA rutting resistance. The methodology of this study was based on correlating the results of the MSCR test and the Hamburg Wheel Tracking Test (HWTT) to HMA field rutting performance. The data matrix for this study included asphalt-binder (PG 64-22) from three different sources, three Texas widely used HMA mixes (fine gradation to coarse gradation), and five in-service highway test sections constructed using the same asphaltbinders and HMA mixes. In general, the MSCR non-recoverable creep compliance parameter, Jnrdiff, showed fairly strong correlations with the HMA rutting performance in the laboratory and field. The percent recovery parameter (R), on the other hand, exhibited the potential to ascertain and quantify the modifiers presence in the asphalt-binders. Furthermore, the test results indicated that material source/supplier has an impact on the rheological properties of the asphalt-binders with the same PG. Overall, the use of the MSCR Manuscript Walubita et al. 2 test to quantify the asphalt-binder high-temperature rheological properties indicated the potential to compliment the laboratory HWTT test for assessing the field HMA rutting performance in terms of the effects of asphalt-binder.

“…To address this shortcoming, Shenoy (2001) introduced a new parameter: G*/(1 − (1/tan(δ)*sin(δ)), which considers the elastic component of binder and hence can be beneficial in determining the rutting resistance of both unmodified and modified binders [8][9][10]. However, none of the parameters, G*/sin (δ), and G*/(1 − (1/tan(δ)*sin(δ)) is able to simulate the behaviour of binders under high stress conditions such as those in the field [11]. Therefore, the Federal Highway Administration (FHWA) developed a new PG binder test called the Multiple Stress Creep and Recovery (MSCR) test to characterise the asphalt binder properties related to HMA rutting [7].…”

Characterisation of Permanent Deformation Behaviour of Asphalt Mix Based on a Combined Elastic Plastic (CEP) Parameter

Permanent deformation or rutting is a major mode of failure in Hot Mix Asphalt (HMA) pavements. The binder used in the asphalt mixture plays an important role in the rutting resistance performance of the mixture. Currently, the Superpave rutting parameter and a more advanced test called multiple stress creep and recovery (MSCR) are the most widely used tests for rutting characterisation of asphalt binders. However, they both have their own merits and demerits. This study was undertaken to introduce a combined Elastic-Plastic (CEP) parameter as an additional binder rheological rutting parameters. The study also aimed at investigating the applicability and potential of this parameter to supplement the existing binder rheological parameters to characterise the properties of asphalt binder related to HMA rutting performance. Additionally, the correlations of the binder rheological parameters with the asphalt mix rutting parameters generated by the dynamic creep and the dynamic modulus tests were investigated. For the polymer-modified binders, Styrene-Butadiene-Styrene (SBS) was added to the PG 70-16 binder at two concentration levels (4, and 6% by the mass of the binder). A dense-graded HMA AC 14 was tested in the Dynamic Modulus (DM) and Dynamic Creep (DC) tests for evaluating the rutting performance. The CEP parameter was found to be much more reliable than the traditional G*/sin (δ) and the non-recoverable creep compliance (Jnr) parameters for evaluating the rutting behaviour of polymer modified asphalt binders, evident from better correlations of CEP with the asphalt mix performance. Unlike Jnr, the CEP parameter revealed a wider range of values, which is comparable with asphalt mixture test results.
