“…Recycled products, fibres, natural and synthetic polymers, fillers and extenders have been added to bituminous binders or into the asphalt mixes during the design of innovative road solutions [4]. For example, treating the aggregate surface with a suitable additive can be a possible solution to enhance moisture damage performance [5]. Nevertheless, these materials may increase the cost of pavement [6].…”

Asphalt pavements inevitably deteriorate over time, requiring frequent maintenance work to ensure the proper serviceability of the road network. Small interventions, such as resurfacing for pavement preservation, are preferable to reconstruction at the end of roads’ in-service lives as they limit environmental- and economic-related impacts. Thin asphalt overlay (TAO) mixture represents a suitable maintenance solution to restore the functional properties of road surfaces. Due to the increasing awareness of the depletion of non-renewable resources and the importance of promoting the circular economy, this study evaluated the possibility of using fully recycled TAO mixes by investigating their volumetric and mechanical properties. Two eco-friendly TAO mixes were designed using recycled aggregates from reclaimed asphalt pavements, a municipal solid waste incinerator, and steel slags in order to meet EN 13108-2 requirements. The TAO mixes differed in regard to the type of bituminous binder (neat/SBS-modified bitumens) and fibres (natural/synthetic) employed. The preliminary results demonstrated that the presence of recycled aggregates did not negatively affect the workability and the mechanical performances of the two sustainable mixtures in terms of stiffness, tensile resistance, rutting and moisture susceptibility. Of these, the TAO mix with neat bitumen and synthetic fibres showed enhanced mechanical performance highlighting the structural effects of the used fibres.

“…Research on polymer-modified asphalt has covered a lot of ground, illuminating the advantages of adding polymers to hot mix asphalt (HMA) mixes. Integrating polymers like styrene-butadiene-styrene (SBS) [13], styrene-butadiene rubber (SBR) [14], and polyethylene (PE) [15] into HMA formulations has been shown to have beneficial impacts in tests. The results of these studies provide strong evidence of improvements in various important pavement performance parameters.…”

The effect of polymer composition on hot mix asphalt (HMA) is the primary focus of this research. The primary goal is to examine how temperature affects HMA's mechanical characteristics and performance, especially concerning polymer concentration. Polymer composition and modifications to HMA, including synthetic rubber and high-density polyethylene (HDPE), are the object of this research. Optimizing HMA polymer mix to improve durability, load-bearing capacity, and structural integrity is the study's key issue. The study also seeks to understand the intricate interaction between polymer concentration and HMA parameters, such as compressive strength, modulus, and stress. The research findings indicate that the maximum load of 68.169 kN was achieved with a mixture containing 5 % synthetic rubber at a temperature of 200 °C. The material exhibited stiffness and resistance to deformation, with an average crack size of 0.01 kN/mm2 and a modulus value of 0.309 kN/mm2. According to the Marshall function, the optimal blend consists of 5 % asphalt mixed at 175 °C. The results indicate that polymer mix considerably affects HMA's mechanical properties, particularly load-bearing capacity and deformation resistance. To optimize HMA performance, polymer content and temperature must be optimized. The results show that HMA with 5 % synthetic rubber under specified temperature settings has better mechanical qualities, including load-bearing capacity and stiffness. These findings help optimize polymer composition for HMA performance. These findings can be used to create more lasting and eco-friendly paving solutions. Road engineers and designers can extend asphalt pavement life and reduce environmental effects by adjusting the HMA polymer mix and temperature

“…These goals are also core elements related to the long-term durability of road surfaces [ 1 ]. Aging modifiers are frequently utilized in asphalt and its mixtures to increase pavement longevity and maintain high service levels [ 2 ]. Among them, nano graphene, rubber powder, petroleum resin, and SBS modified asphalt have good compatibility and excellent performance.…”

After aging, the adhesiveness of asphalt deteriorates, leading to a reduction in the durability of asphalt mixtures and affecting the service life of asphalt pavements. To enhance the anti-aging performance of asphalt, this study employed the method of melt blending to prepare three types of modified asphalt: graphene/SBS modified asphalt (G/SBSMA), crumb rubber/SBS modified asphalt (CR/SBSMA), and petroleum resin/SBS modified asphalt (PR/SBSMA). Different dosages of the three types of modified asphalt were tested for changes in conventional performance indicators. The optimal dosages of graphene, crumb rubber, and C9 petroleum resin were determined to be 2%, 15%, and 5%, respectively. Based on the theory of surface free energy, the effects of anti-aging agents on the microscopic properties of SBS modified asphalt before and after aging were analyzed using the three-liquid method. The mechanisms of strength attenuation at the asphalt–aggregate interface under water exposure and aging were revealed. The results showed that with the increase of aging gradient, the asphalt-aggregate biphasic system became more active. The cohesive energy and peel energy of SBS modified asphalt increased continuously, while the adhesive energy decreased continuously, leading to a decrease in the energy ratio parameter. Resin-based anti-aging agents exhibited the most significant improvement in asphalt adhesion performance, while graphene demonstrated a more stable enhancement in asphalt’s water stability during the aging stage.
