“…On the other hand, the SBS 6/S bitumen shows higher stability with the morphology of the PMB in the top and the bottom parts of the tube being very similar. These results are in agreement with other research published on the advantages of using sulphur as a cross-linking agent with PMBs (Mandal et al, 2015;Das & Panda, 2017;Zhang et al, 2010).…”

“…The advantages of using sulphur in unmodified and elastomer modified bitumens have been investigated by several researchers (Das & Panda, 2017;Kumar, & Khan, 2013;Mandal, Sylla, Bahia, & Barmand, 2015;Masegosa et al, 2012;Zhang, Yu, Wu, 2010). Considering the procedures followed for bitumen modification in the referenced works, it appears that sulphur can be used as a modifier in bitumen with concentrations up to 5% by the weight of bitumen (Das & Panda, 2017). However, in the early '70s, the use of sulphur in road bitumens received extra attention prompted by the abundance of this material from industrial processes.…”

Polymer additives are widely used to improve the performance of road bitumens including their resistance to hardening during oxidation, although their oxidative inhibitor effect has not been well documented. This study aims to investigate the effect of laboratory-simulated ageing on the microstructure, and rheological properties of Polymer Modified Bitumens (PMBs) prepared with a Styrene-Butadiene-Styrene (SBS) copolymer and sulphur as a cross-linker. The laboratory ageing was conducted through the Rolling Thin Film Oven (RTFO) and the Pressure Aging Vessel (PAV) procedures. The unaged and aged binders were characterised using the Multiple Stress Creep and Recovery (MSCR) test, Gel Permeation Chromatography (GPC) and fluorescence microscopy. The MSCR test showed that the cross-linked polymer had a higher capability of mitigating the effect of bitumen hardening on the rheological response, while for the PMBs without cross-linking, the polymer effects decreased significantly after RTFOT ageing. The GPC results showed that the aromatics, resins and asphaltenes fractions of the unmodified bitumens shifted towards heavier molecules after one cycle of PAV ageing but showed limited variation with further ageing. Similar behaviour was observed for the uncross-linked polymer binders, while for the cross-linked polymer binder, the behaviour depended on the polymer concentration.

“…Zhou et al [59] added 10% sulphur to bio-modified rubberised (BMR) bitumen at a temperature of 155 ± 5 • C for 30 min using a mixer at 1000 rpm. Das and Panda [72] added 2% of sulphur to bitumen at various temperatures ranging from 100 to 160 • C, with a 10 • C increment for various mixing times of 15, 30, 45, 60 and 75 min.…”

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.

The bitumen is used as binder in bituminous pavements. The heavy growth of traffic loads and their contact tyre pressure with different climatic conditions improve the demand of bituminous flexible pavement. The bituminous pavement failure occurs due to heavy traffic load which can cause higher stress as well as temperature variations on surface of pavement due to which cracking, rutting occurs. To protect the surface course binders from such distresses, binders can be associated with various modifiers which can improve the durability, performance, quality of pavement etc. In this paper locally available sulphur added to the conventional VG 30 bitumen of different percentages i.e. 1 to 9% to form modified binder. The bituminous concrete mixes of grading -2 accompanying from mid-point gradation using sulphur as modifier. This research work states the physical properties, Marshall Stability test properties of bituminous concrete mixes of VG 30, optimum sulphur content of bitumen using sulphur as modifier. The main objective of the research work is to investigate the effect of addition of sulphur of various percentages on the physical properties and replacement of fly ash as filler in of sulphur modified bitumen to find out optimum fly ash content. This study helps to find out the wholesomeness of sulphur modified bitumen by virtue of which the consumption of plain bitumen can be reduced and also recycling of waste materials.
