The number of transport or vehicles on the road is increasing, which cause the road pavement or asphalt surface exposed to greater loading. Problems such as permanent deformation, cracking, fatigue, and skidding happened because of this repeated loading. There are many studies have been done to determine the suitable waste materials that can be used in order to improve resistance to rutting and fatigue cracking due to filler hardening and improve adhesion of filler to aggregate. The aim of this study is to investigate the effect of CBA on engineering properties of asphalt mixture. The different percentages of CBA (0%, 2%, 4% and 6%) were added to the asphalt mixture. The 60/70 penetration grade asphalt was used. The performance of the samples was evaluated through Marshall Stability, indirect tensile strength, resilient modulus, dynamic creep and image analysis. From the result obtained, there are significant effect comes from the addition of CBA. The result show that the addition of CBA in range of 2 to 4% produces the best outcomes for the density, stability, stiffness and flow while 6% for indirect tensile strength, dynamic creep and resilient modulus. Thus, it can conclude that the existence of CBA can enhance the performance of asphalt mix.

“…Polymer modification is a frequently used approach to improve the performance of bitumen. The use of polymer-modified binders (PMBs) in asphalt mixtures offers numerous benefits, such as their lower thermal susceptibility and greater resistance to rutting, low-temperature cracking, and fatigue [19], which results in the reduction of life cycle costs of asphalt pavements [20]. Elastomers, plastomers, and recycled tire rubbers are the most frequently introduced polymers.…”

This review scrutinizes current research on new methods for enhancing bituminous binder performance through radiation and radical grafting of polymer modifiers of bitumen. It investigates innovative methods, including using waste polymers as modifiers and applying radiation for polymer grafting, to overcome challenges like high costs, low aging resistance, and storage stability issues, of which separation of phases polymer/bitumen is the most significant obstacle. These advanced modification techniques promise sustainability through the decrease of the carbon footprint of transportation systems by improving the properties and durability of binders. Additionally, this review discusses the parameters and mechanistic aspects from a scientific perspective, shedding light on the underlying processes that contribute to the improved performance of modified bituminous binders.

“…The dynamic creep modulus increases to 6% and then decreases to 8% as the percentage of waste plastic increases. Therefore, it is possible to conclude that incorporating waste plastic into the asphalt mixture can minimize low-temperature cracking of pavement surfacing and permanent deformation in the form of rutting[34].…”

Cracking is a typical problem that deteriorates the strength and longevity of a pavement structure. Waste plastic in pavement construction is cost-effective and environmentally friendly. The use of waste plastic has been growing in recent years. Adding waste plastics to the asphalt mixture would improve its physical and mechanical characteristics. As a result, it is a sustainable and long-term solution that helps to reduce plastic waste and preserve the environment. This research aims to develop the image analysis and assess the characteristic of modifying bitumen with different percentages of plastic wastes (0%, 4%, 6%, and 8%). Using blending processes, modified bitumen was prepared. The binder used in this study is penetration grade PEN 60/70. Marshall Test, Indirect Tensile Strength, Resilient Modulus and Dynamic Creep Modulus test were carried out to determine the optimum percentage of waste plastic in asphalt mixture. The modified binders can be used in high-performance asphalt mixtures, as well as to use a well-developed image analysis technique using ImageJ software to characterize asphalt pavement surfaces. The result shows that the modified asphalt mixture is more efficient than the conventional asphalt mixture. Addition of the waste plastic proved sufficient to increase the performance of the asphalt pavement as modified asphalt mixture performance is more stable than conventional mixture.
