“…Its complex molecular chains create strong bonds and structures, producing a number of unique traits, such as elasticity, the capacity to withstand high tension, thermal stability and resiliency, which contribute to its use in polymer-modified bitumen [2]. In South Asia, NR is produced by the native tree Hevea brasiliensis, which, when combined with other materials that act as insulating membranes and additives, is has been widely utilised in various products in numerous sectors such as the tire industry, footwear and construction [5].…”

“…Thus, it is commonly used even though it has both liquid and solid properties [6,7]. Even though its features contribute to improving water resistance, the use of NR is consistent with the environmental requirement to use recycled materials and environmentally friendly alternatives to conserve finite natural resources [5].…”

“…NRL polymer can be used as a modifier to enhance bitumen's physical qualities, such as increasing the softening point, reducing penetration while enhancing the penetration index, and improving the properties of shortand long-term ageing [3,14,15]. NRL also addresses the common problems of bitumen, such as fatigue, permanent deformation, fracture strength and thermal cracking resistance, helping improve the durability of bitumen pavement [5,16]. Moreover, the addition of NRL improves the rheological properties by improving the rutting factor (G * /sin δ), enabling bi-tumen to resist deformation on the road surface despite high traffic loading, thus achieving better rutting and fatigue resistance [16,17].…”

Conventional bitumen pavement is no longer suitable for handling increasing loads and weather variations, which cause road deterioration, Thus, the modification of bitumen has been suggested to counter this issue. This study provides a detailed assessment of various additives for modifying natural rubber-modified bitumen used in road construction. This work will focus on the use of additives with cup lump natural rubber (CLNR), which has recently started to gain attention among researchers, especially in rubber-producing countries such as Malaysia, Thailand and Indonesia. Furthermore, this paper aims to briefly review how the addition of additives or modifiers helps elevate the performance of bitumen by highlighting the significant properties of modified bitumen after the addition of modifiers. Moreover, the amount and method of application of each additive are discussed further to obtain the optimum value for future implementation. On the basis of past studies, this paper will review the utilisation of several types of additives, including polyphosphoric acid, Evotherm, mangosteen powder, trimethyl-quinoline and sulphur, and the application of xylene and toluene to ensure the homogeneity of the rubberised bitumen. Numerous studies were conducted to verify the performance of various types and compositions of additives, particularly in terms of physical and rheological properties. In general, additives enhance the properties of conventional bitumen. Future research should investigate CLNR because studies on its utilisation are limited.

A detailed analysis of the rubber composites is necessary for the designing and fabrication of advanced rubber products. In this study, composite materials are synthesized by adding different nanofillers of carbon black nanoparticles into epoxidized natural rubber (ENR). The specific characteristics of carbon black (CB) affect the crosslinking density between CB and polymeric chains in ENR. The effects of particle size, structure, thermal conductivity, and functionality of CB on rheology and mechanical properties of filled reinforced ENR are examined. The composite materials are thoroughly characterized for their abrasion, rheology, tensile, hardness, elongation, resilience, and compression behavior. The results revealed that various properties of composite materials depend on the characteristics of the reinforcing CB fillers. It was found that lower particle size and ordered structure provide good tensile strength, tear strength, abrasion, and aging resistance. In contrast, larger particle size and a lower ordered structure provide high flow rate, low hardness, excellent re-bounce, and good compression set characteristics.
