“…As a result, it prevents molecular mobility, especially for asphalt bindersaturated components, by strengthening the lignin-asphalt binder interaction. Hence, lignins improve the performance, increase it at high temperatures, and increase the resistance to rutting [28].…”

“…Unlike hemicellulose and cellulose, lignin does not decompose within a specific temperature range. The reason is that it is a complex three-dimensional macromolecule with various chemical Advances in Civil Engineering bonds [28]. Instead, lignin degrades over a wide temperature range because of the abundance of functional groups with varying degrees of thermal stability.…”

Biomasses are environmentally friendly additives that lower pollution in pavement engineering because of their biodegradability. On the other hand, to build a safe, long-lasting pavement, rutting prevention is crucial. This study provides a comprehensive review of the efficacy of biomass as recyclable materials in reducing rutting and enhancing characteristics of asphalt mixtures. According to findings, the hydrocarbon polymer properties of lignin and biomass ash improve asphalt binder consistency, hardness, and function at high temperatures. The results showed that biochar, due to its solid shape, enhances the stiffness and viscosity of the mixtures. The high-temperature performance of asphalt binder is improved by bioshell waste, which increases rutting parameters. Thus, biomass like ash, lignin, and biochar can increase asphalt binder rheology and rutting resistance due to chemical forces such as Van der Waals and hydrogen ions. The macroscopic and microscopic investigation also shows higher interaction and better adhesion in bioasphalt. However, asphalt binders containing bio-oil exhibited no unique behaviors due to their lubricant impact. Based on the estimation of the life cycle assessment (LCA), it was determined that biomass utilization has the potential to decrease the cost and CO2 emissions of pavement engineering by as much as 10% and more than three times, respectively. An examination of recyclability revealed that biomass utilization can decrease the requirement for additional stabilizers by as much as 20%.

“…The composition and microstructure of the mastic as well as its rheological characteristics, have a significant impact on the asphalt mixes' high-temperature stability and low-temperature deformation resistance. Recently, fibers have become a common additive or modifier to enhance the adhesion characteristics of asphalt mastic, increase the shear resistance of the mixture, and extend the pavement's service life [1,2]. The fibers disperse uniformly throughout the asphalt mixture and form a network structure that produces reinforcing and bridging effects, significantly enhancing the stability of both asphalt and asphalt mixtures.…”

Incorporating fibers into asphalt mixtures as additives and stabilizers can significantly enhance the performance of asphalt pavements. This study aimed to analyze the impact of using basalt and bamboo fibers as modifiers on the properties of asphalt mastics. The effects of different types of fibers on rutting resistance, fatigue resistance, elastic recovery, and low-temperature cracking performance were tested using frequency scanning, linear amplitude scanning (LAS), multiple stress creep and recovery (MSCR), elastic recovery, and bending beam rheometer (BBR) experiments. The study results suggest that adding fibers into asphalt mastics can effectively improve their stiffness, and the higher the fiber content, the better the stiffness enhancement. Moreover, the characteristic flow index of asphalt mastics grows gradually with the rise in temperature, indicating that these materials exhibit near-Newtonian fluid behavior at elevated temperatures. Furthermore, incorporating fibers significantly enhances the high-temperature rutting resistance of asphalt mastics. However, the addition of fibers did not demonstrate any appreciable benefits in terms of fatigue resistance. The elasticity of asphalt mastics cannot be significantly changed by fiber content without compromising their elastic recovery. Surprisingly, the study’s findings showed that adding basalt fibers to asphalt mastics did not improve their resistance to low-temperature cracks. On the other hand, it was discovered that the ability of asphalt mastics to resist cracking at low temperatures could be made up for by the use of bamboo fibers as a modifier together with a raised temperature. Overall, it was discovered that bamboo fibers performed better than basalt fibers at improving the performance of modified asphalt mastics.

“…For these reasons, bio-binders are currently considered a promising solution for flexible pavements. They consist in a partial or total replacement of bitumen, which derives from the distillation process of crude oil, with various bio-resources such as animal waste, bio-oils (wood, sunflower, corn, soybean) [2][3][4] waste cooking oil [5], and lignin [6][7][8] In particular, lignin is gaining much interest since it is largely available in nature [9][10][11]. It can be in dusty or liquid form and derives from specific pyrolysis [12] or hydrolysis [13] processes carried out on wastes of the wood pulp and paper industries.…”

“…Overall, nonunivocal results were found in the literature on the fatigue performance offered by lignin-based asphalt binders and mixtures. The highlighted discrepancies could be due to the strong influence of the raw material from which lignin derives, its consistency (i.e., powder, liquid, fiber form) and replacement amount [6] and, above all, to the fact that the available results reflect the specific boundary conditions given by the tests performed [16,27].…”

In the near future, the world of civil and building engineering will be dominated by the advent of bio-materials. Even the road paving sector is involved in the transition towards more sustainable solutions, promoting at the same time environmental benefits and economic savings. Currently, one of the main goals is to ensure that bio-binders offer good performance, at least comparable with that offered by conventional materials. In the last decades, the exponential increase in traffic volumes has led to various types of asphalt pavement distresses, among which fatigue cracking is one of the most common. Within this context, this study presents the characterization of a bio-based asphalt mixture obtained by replacing 30% of bitumen with lignin, which was compared with a reference asphalt mixture containing a plain bitumen characterised by the same penetration grade. Laboratory produced and compacted specimens were subjected to complex modulus and cyclic fatigue tests with the Asphalt Mixture Performance Tester (AMPT). Both unaged and long-term aging conditions were investigated. The tests and the subsequent analyses were based on the simplified viscoelastic continuum damage (S-VECD) approach. Overall, the results showed that the presence of lignin led to a lower aging susceptibility, but also caused a slight reduction in fatigue life due to an increase in the material stiffness. Furthermore, the obtained results confirmed previous findings deriving from the study of the two binders and from the conventional characterization of the same asphalt mixtures as well.
