“…ey also concluded that the softening value of EPS-modified bitumen improved as the percentage of EPS content increased, indicating that using EPS-modified asphalt for the construction of flexible pavement in hot temperature conditions would be the best alternative [19].…”

“…In a prior investigation, the authors discovered that when the penetration and softening point of EPSmodified asphalt increased, the ductility and flow values decreased. According to Marshall stability test results, the stability of AC-containing EPS was increased with varying percentages of EPS substitution up to 40%, but after that, a little decline in their stability values was noted at 50% replacement [19].…”

“…Because it is light and cool, it is widely employed in many concrete applications, particularly in the production of concrete blocks and in geotechnical engineering [17,18]. Anwar et al [19] investigated the effects of EPS as a binder replacement at seven different dosages ranging from 5% to 50%. ey concluded that adding EPS to modified asphalt concrete improves its stability.…”

The disposal of massive amounts of waste, particularly nondecaying waste, is now a major issue for both developed and developing countries. One of the most sustainable solutions to this problem is to recycle garbage into valuable items. Expanded polystyrene, which is manufactured in large quantities, is one of these waste materials. This is being used globally as packaging material, construction material, and household appliances. The waste expanded polystyrene (EPS) is necessary due to its biodegradability, and aesthetically, it has a great negative impact on the environment. The goal of this research would be to see how shredded waste EPS affects the characteristics of asphalt and asphalt concrete. For this, four separate serial asphalt concrete samples were made with varying amounts of shredded expanded polystyrene waste (0.25, 0.50, 0.75, and 1% by the weight of the total aggregate) and five different percentages of asphalt (4.0, 4.5, 5.0, 5.5, and 6.0% by the weight of the total aggregate). In this study, 60/70 grade bitumen was used. Modified asphalt concrete properties were examined and compared with those of the standard specimens. The penetration, ductility, softening point, flash point, and fire point of the asphalt will all be affected by the addition of EPS plastic waste. The optimal asphalt content of the conventional specimen was 5.1 percent, and different percentages of EPS with OAC were applied. The mechanical properties of all specimens were studied in terms of Marshall properties after Marshall specimens were created with regard to OAC by adding EPS. It has been discovered that applying a 0.5% addition produces improved results than other methods. Simultaneously, as the EPS percentage increased, the stability value increased by approximately 82.61% compared to the traditional mix.

Styrofoam is a recyclable petroleum origin product. However, releasing it and/or its waste into nature causes permanent damage to environment and human health owing to toxic materials that it contains. This study was set out on sustainable recycling of waste styrofoam (WS). To recycle the waste, it is used as a modifier in bitumen. In this respect, three type of bitumen in different penetration grade, which are one used for modification the other two used for reference in optimization analysis and WS in five different rate ranging from 1% to 5% by weight of bitumen were utilized. Different conventional test methods were applied on each samples to identify the effect of WS rate on bitumen basic characteristics. Optimum rate of WS required to produce new grade bitumen was evaluated based on modification index found for all test results. The test results showed that WS modification changes the bitumen properties, significantly. It can be possible to produce new graded bitumen using certain rate of WS. Test method was found a critique factor, since optimum rate of WS considered based on modification index changes due to the test method. Overall, the recycling WS using as a modifier in bitumen can an alternative, energy efficient, economic, and eco-friendly method.

Eco-friendly waste utilization helps in the development of sustainable infrastructures. Recently, researchers have focused on the production of road infrastructures using the circular economy concept of human safety. The objective of this study is to investigate and explore the utilization of optimum polymer waste content for the development of polymer-modified asphalt mixtures using response surface methodology (RSM). RSM based on Box–Behnken design (BBD) was employed to optimize experimental design and included three factors: X1, polymer type; X2, polymer contents; and X3, testing day. The optimized responses determined by the RSM were as follows: MS of 42.98 kN, MF of 5.08 mm, and MQ of 8.66 kN/mm, indicating a favorable and consistent precision in comparison with experimental values. Moreover, the Marshall characteristics of samples prepared with PE were quite improved compared to PET. In conclusion, the incorporation of such polymer wastes in road construction is a sustainable and cost-effective way of improving their engineering properties. This study will help in the development of sustainable road infrastructures supporting human safety and environmentally friendly practices.
