“…Among the polymer fiber that is regularly used in asphalt mixtures, for this reason, are steel, glass, natural, and synthetic fiber. This result is in line with a recent study that found the presence of fibers changes the mixture's viscoelasticity, increases its dynamic modulus, improves its sensitivity to humidity, improves flow coherence, and prevents rutting [6][7][8][9][10].…”

“…Steel fiber is one of the new potential additives to asphalt mixes that demonstrate a high durability pavement, increasing the base's fatigue life and enhancing resistance to reflective asphalt cracking [8]. The excellent performance of steel fiber indicates that the material may provide a combination of high functionality and good mechanical properties [10][11][12][13][14].…”

The use of various fibers in asphalt mixes has been developed and applied to enhance pavement performance. The conventional asphalt mixture can be improved by including steel fibre as an additive in the asphalt mixture. However, the use of steel fibre in SMA mixtures was not widely studied. Consequently, the objective of this study was to evaluate the effect of steel fibre on the volumetric properties and characterize the performance of steel fibre in SMA mixture. Different steel fiber proportions of 0%, 0.3%, 0.5%, and 0.7% by the total weight of the mixture were used in this study. The test conducted includes the Marshall stability and Flow test, and the Resilient Modulus Test. Response Surface Methodology (RSM) from Design Expert Software was then performed to determine the most optimum properties from the experimental data. The test results revealed that adding steel fiber greatly improved the SMA mixture’s resistance to deformation while also increasing its stability, reducing the abrasion loss, and increasing the stiffness of the SMA mixture. Optimized performance was observed at 0.3% steel fiber content and 1598 MPa of resilient modulus. The relative error results show acceptable agreement between the prediction and the experiment which is considered tolerable and acceptable. This demonstrates that the software optimization of the specific SMA with steel fiber characteristics by the RSM technique has the desired precision for laboratory tests.

“…The study into the incorporation of steel fibre in hot mix asphalt also draws the attention of researchers, who believe that it is advantageous for enhancing the strength of asphalt hot mix [38]. A research on steel fibre-reinforced asphalt concrete was conducted to evaluate several factors of steel fibres, such as aspect ratio, section type, and roughness by evaluating the cracking resistance using an indirect tension test at low temperatures.…”

“…It is important to note that the steel fibres collected from discarded tyres come in different shapes and lengths, and may also include rubber contamination. These attributes influence the efficiency of this substance when integrated into hot mix asphalt [38].…”

The amount of waste tyres is expected to increase with the surge of vehicle ownership in Malaysia as tyres are vehicle vital components that require regular replacement. The improper disposal of waste tyres has generated environmental issues. Energy recovery through burning, recycling, and disposal in legal and illegal landfills are common methods in disposing of waste tyres in Malaysia. Studies show that waste tyres contain steel fibre that can be extracted and has the potential to be used in construction. In Malaysia, existing methods of material recovery are shredding and pyrolysis. The steel retrieved from waste tyres exhibits good adhesion with mechanical strength recorded up to 2165 MPa and a modulus of 300. However, the uneven shape, length, and geometry can lead to a balling effect when incorporated into concrete but with a proper mix proportion this issue can be managed. Addition of recycled steel fibre to concrete can enhance its structural strength and crack-bridging effect while the use of recycled steel fibre in hot mix asphalt can enhance its tensile strength and toughness. The utilisation of steel recovered from waste tyres presents an opportunity to address environmental concerns related to waste tyre disposal and its potential applications.

This review article provides a comprehensive analysis of the transformative potential of waste plastic in South Africa, with a specific focus on high-density polyethylene-modified bitumen and polyethylene terephthalate plastic fibres asphalt. The review encompasses a wide range of topics, including the environmental and socio-economic impacts of plastic waste, the current state of plastic waste management practices in South Africa, and the potential use of waste plastic in road construction. The aim is to critically evaluate the compatibility of recycled waste plastics as bitumen modifiers and fibre to enhance road performance. Additionally, it explores the challenges and opportunities associated with the incorporation of waste plastic in road construction, shedding light on the environmental, economic and technological aspects. The review also emphasizes the need for targeted interventions and collaborative efforts from the South African government and industry stakeholders to address plastic waste management challenges and promote sustainable infrastructure development. Overall, this review provides valuable insights into the transformative potential of waste plastic in South African road maintenance and offers a roadmap for future research and initiatives in this critical area of sustainable development.
