“…As a result of the stiffening brought about by incorporating NR into asphalt binders, a general improvement against rutting was seen that the binder might keep its rutting potential up to 85°C. Both control and modified asphalt binder (i.e., 2.5%, 5%, 7.5%, and 10%) can be classified as PG based on performance grades (70, 70, 76, 76, and 82), respectively [68]. In another study, cashew nut shell liquid (CNSL) was used with an increase of 0.5%-3%.…”

“…In certain regions, the costs associated with conventional additives (e.g., lime and cement) can be up to three times greater than those of bio-based materials. In addition, the expenses related to conventional stabilizers might be considerably greater due to their bulky nature, especially during long-distance transportation to road sites [68]. Biobased additives, due to their recyclability, are widespread on earth.…”

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%.

“…Natural rubber can be utilized as a thermoplastic elastomer form to create modified polymer bitumen. The thermoplastic elastomer known as natural rubber, commonly referred to as latex, helps improve the stiffness and elasticity of asphalt while reducing its sensitivity to temperature fluctuations (Daniel et al, 2019;Poovaneshvaran et al, 2020;Jamaris et al, 2021). Natural rubber is available in liquid and solid forms.…”

Flexible pavement itself uses asphalt binder as a binding material between aggregates, but with the increasing number of vehicle loads, the ability of flexible pavement needs to be improved. A rubber is a natural polymer material that can be used to improve asphalt mixtures’ performance. This paper aims to analyze the effect of using pre-vulcanized latex on characteristics in hot mix asphalt wearing course mixtures. Pre-vulcanized latex is used as a substitute material for asphalt binder at levels of 7% and 9% by weight. Based on Marshall test results, the AC-WC mixture using pre-vulcanized latex achieved Marshall stability of 11.63 kN or increased by 32.28% at 7% content, while at 9%, it resulted in Marshall stability of 10.69 kN or increased by 21.06%, compared to the specification limit, which is 8.83 kN. The stiffness modulus test results of the asphalt mixture showed that at a temperature of 25°C, there was an increase of 17.46% and 28.26%, respectively, when using pre-vulcanized latex at levels of 7% and 9%. These findings indicate that the use of pre-vulcanized latex as a partial replacement for asphalt has a positive impact on temperature changes in the pavement material.

“…Latex of ratio (2.5, 5.0, 7.5 and 10)% has used with bitumen (pen 60/70) and evaluated penetrability, softening point and viscosity; in addition ductility, loss upon heating and dynamic shear rheometer. The addition of latex led to hardened the bitumen, increases the viscosity and provides better resistance against rutting [8].…”

The influence of natural rubber along-side with chlorine gas on the bitumen blends characteristics have inspected. The modification performed through passing chlorine gas on molten bitumen mix prepared using bitumen and rubber latex of variety percentages. Penetration, penetration index, ductility and softening point have tested. In addition, viscoelasticity, rutting resistance and thermal stability have measured using dynamic shear rheometric analysis and differential scanning calorimetry, respectively. The chlorination has confirmed via Fourier-transform infrared spectroscopy analysis and asphaltene ratio determination. The acquired data showed an improvement in the thermal stability besides obvious enhancements in the viscoelasticity and rutting performance of the resulted blends. The results give clear advantage, for potential usage of such blends in the road paving application.
