“…This specific condition causes the foam spongy but strong with a very lightweight property, resulting in efficient load-bearing and heat insulation. Recycling of that EPS foam can be applied in many ways e.g., admixture for the emulsion paint, admixture for the cement mortar, or modification of the asphaltic binder [3][4][5]. However, in the sense of Civil Engineering, the EPS foam can be used as a cohesive binder when it was dissolved in any suitable solvents e.g., acetone or toluene.…”

Expanded Polystyrene (EPS) foam wastes become a huge environmental issue as most of them are non-biodegradable materials and are disposed of inappropriately. It was reported that the amount of plastic and foam wastes for food containers and other packagings was evidently increased during the past 5 years, especially since the COVID19 pandemic. This work studied the development of the polymeric foam binder from the EPS foam waste for the production of green construction blocks or pavement tiles. The types of solvent (acetone and toluene) and the amount of additional EPS foam binder were investigated. The results show that the appropriate mixtures contained EPS foam binder from 15% to 30% to achieve maximum compressive strength at approximately 10 to 12 MPa with the optimal unit weight of 1,600 to 1,900 kg/m3. Those outcomes have equally passed the strength class of Thai Industrial Standard (TIS 57 and 77) for construction brick and block. This eco-friendly technique could facilitate value-added production and reduce the environmental impact of EPS wastes disposal. Moreover, it is one of the alternative approaches to promote greener and cleaner production for environmentally friendly construction materials.

“…They found that the addition of 1% EPS, by weight of total aggregate, the maximum EPS content they used, produced the maximum flash, fire, and softening points but the minimum ductility values. Yıldız et al [11] investigated modifying a base asphalt binder with waste EPS with ratios of 2%, 4%, 6%, and 8% (by weight of asphalt binder) and the following tests were applied to the modified binders: ductility, softening point, flash point, penetration and specific gravity. They found that increase in EPS content decreased the penetration and ductility values.…”

EPS (Expanded polystyrene) is widely used in construction and packaging industries. Unfortunately, EPS is not mostly recyclable because it might not be economically feasible to store, transport, and process EPS so that it becomes recyclable. Therefore, alternative waste management strategies are urgently needed. The main objective of this study is to experimentally investigate the potential use of waste EPS in asphalt binder modification. As part of this study, a base asphalt binder with a Penetration grade of 70/100 was modified with waste EPS in four different ratios (0%, 1.5%, 3% and 4.5%, by weight of asphalt binder). The modified asphalt binder specimens were tested based on several physical (penetration, ductility, softening points and viscosity) as well as rheological/Superpave binder grading system tests including Rolling Thin Film Oven (RTFO), Pressure Aging Vessel (PAV), Dynamic Shear Rheometer (DSR), and Bending Beam Rheometer (BBR). Based on the tests results, rheological and engineering properties of the modified asphalt binders were compared with the ones of the base binder so that effect of waste EPS addition on the properties of the base binder was evaluated; and how the Superpave binder grades of the modified binders were changed with the additions of waste EPS was discussed. It was found out that modifying asphalt binders with EPS provided them with a better rutting resistance at the expense of lowering their fatigue and low temperature cracking resistance. Overall, it could be concluded that waste EPS can be potentially used in the asphalt binder modification by paying special attention to these factors, and it should be noted that using waste EPS in the asphalt binder modification has many economic and environmental benefits.
