“…Moreover, the specific gravity and density of the plastic waste need to be evaluated in order to ensure the material are lightweight. Vaslestad et al [20] found that the insertion of lightweight fill material will not give stress to the soil. It can be deduced that the plastic waste has viability as a reinforcement material in soil reinforcement technology.…”

The current statistic shows that the percentage of plastic has significantly increased in the landfill and leads to environmental issues due to its non-biodegradable characteristic. However, these challenges can be turned into opportunities by reusing and recycling such waste for civil engineering applications. Hence, the focuses of this paper are to analyze the possibility of utilizing plastic waste in the soil reinforcement field using VOSviewer software and to evaluate the chemical, thermal, physical, and mechanical properties of the plastics (plastic straw, plastic bottle, and plastic bag). The data for this study was collected from the articles published in Scopus. Nevertheless, there are very limited articles that relate soil reinforcement with the thermal, chemical, physical, and mechanical properties of plastic waste. Therefore, this paper aims to evaluate the properties of plastic waste, which were plastic bottles, plastic bags, and plastic straw. The properties of plastic waste have been investigated to ensure it meets the requirement for soil reinforcement technology. The Fourier transform infrared (FTIR) spectra indicated the presence of carbon and hydrogen chains in those plastics waste. The plastic straw, plastic bag, and plastic bottle were degraded at 382°C, 456°C, and 449°C, respectively. This finding indicated that all of these plastics waste were thermally stable in the tropical temperature. Moreover, the densities of the plastics waste were less than 1 g/cm3, which contributes to the lightweight material and it’s very crucial to eliminating the self-loading from the reinforcement material.

“…Lightweight construction/fill materials include expanded polystyrene (EPS) block geofoam [5,6], and soil blends incorporating various lightweight additives (e.g., tire-derived aggregate [7][8][9][10], wood chips, and mineral pumice). Applications for the former in transportation infrastructure include, for instance, bridge foundations supported by EPS-block geofoam embankments founded on soft soil [11], protecting buried pipelines and culverts [12] and reducing seismic excitations to soil-steel bridges [13]. For the latter (soil blends incorporating lightweight additives), it is known that the type, aspect ratio and content of these additives have important roles in the mechanical properties of the mixtures.…”

Lightweight fill can be advantageous in embankment construction for the purposes of reducing the (i) bearing pressures on the underlying soil foundation, (ii) destabilizing moments for constructed earthen slopes, and (iii) earth pressures acting behind retaining walls. This paper investigates the merits/limitations of particulate expanded polystyrene (EPS) beads mixed with clayey sand (CS) soil as lightweight fill, considering both geotechnical and environmental perspectives. The bench-scale geotechnical testing programme included standard Proctor (SP) compaction, California bearing ratio (CBR), direct shear (sheardox), oedometer and permeability testing performed on two different gradation CS soils amended with 0.5, 1.5 and 3.0 wt.% EPS, investigating two nominal bead sizes equivalent to poorly-graded medium and coarse sands. Compared to the unamended soils, the compacted dry density substantially decreased with increasing EPS beads content, from 2.09 t/m3 (0 wt.% EPS) to as low as 0.33 t/m3 for 3 wt.% (73 v.%) of larger-sized EPS beads. However, from analyses of the test results for the investigated 50 to 400 kPa applied stress range, even 0.5 wt.% (21 v.%) EPS beads caused a substantial mechanical failure, with a drastic decay of the CBR and compressibility parameters for the studied CS soils. Given the more detrimental environmental cost of leaving myriads of separate EPS beads mixed forever among the soil, it is concluded that the approach of adding particulate EPS beads to soils for producing uncemented lightened fill should not be employed in geotechnical engineering practice.
