“…Recycled materials such as electroplating sludge and fly ash have also been utilized to manufacture lightweight concrete, paver blocks, bricks, and structural components [39]. Limited studies have investigated the use of sand and acrylonitrile styrene acrylate (ASA) polymer for outdoor applications such as sidewalk paving bricks [40]. This has the potential to be further extended into road surfaces with PC due to the high durability, UV resistance, and high temperature resistance of this material.…”

Concrete contributes 8% of all global carbon emissions making the need to find substitute critical for environmental sustainability. Research has indicated the potential for recycled plastics to be used as concrete substitutes. This study extends existing research by investigating the use of polycarbonate (PC) in plastic sand bricks as a mechanical equivalent to concrete. PC has high compressive strength, durability, impact strength, thermal resistivity, clarity, fatigue resistance, and UV resistance. This work provides a method and mold to produce a matrix of sand-plastic sample compositions with dimensions adhering to ASTM D695 standard for compressive properties of rigid-plastic. Compositions of 0% (control), 20%, 30%, 40%, and 50% sand by weight were tested. Samples were tested for compressive strength until yield and stress-strain behaviors plotted. The results for 100% PC demonstrated an average and maximum compressive strength of 71 MPa and 72 MPa, respectively. The 50% PC and 50% sand composition yielded an average and maximum compressive strength of 71 MPa and 73 MPa respectively with an increase in compressive stiffness, and transition to shear failure resembling cement. With a composite density of 1.86 g/cm3 against concrete’s average 2.4 g/cm3, and a compressive strength exceeding commercial concrete demands of 23.3 MPa to 30.2 MPa, this lightweight alternative meets the strength demands of concrete, reduces the need for new construction materials, and provides an additional recycling opportunity for nonbiodegradable waste plastic.

“…The main principle of these systems is to manufacture the designed parts based on the layer-by-layer approach, resulting from the additive production process without any subtractive or removal steps such as milling, drilling, grinding, or cutting. Metal, polymer, and composite materials can be processed with additive manufacturing technologies, and the technology has been used in many industrial areas, such as automotive [9], aerospace [10,11], health [12][13][14][15] and construction [16,17].…”

Additive manufacturing is a widely used method in industry and research areas. In particular, fused deposition modelling is the most prevalent technique used by many professional and nonprofessional users. Many polymers can be used with this system, including thermo polyurethanes (TPU). TPUs have excellent elastic properties and high endurance against corrosion, humidity, and oil, and they ex-hibit a great absorbance capability to noise and vibrations, biocompatibility, and chemical resistance. Thermoplastic polyurethane (TPU) is also preferred for use in 3D/4D printing applications due to its easy casting, injection, and extrusion capabilities and its shape memory features. In this study, flexible TPU and carbon-mixed TPU were used to produce specimens with fused deposition modelling tech-niques at different infill ratios with the same patterns. The effects of the infill ratio within the different and same materials were investigated in terms of wear and friction profiles. Additionally, thermal and worn surface images were taken using a digital microscope. The hardness and diameter value altera-tions were also investigated for different materials and infill ratios. As a result of the study, material al-teration is more effective than the infill ratios in all parameters.

“…Jin et al conducted a study on using stamp sand and ASA plastic composite as pavement or road surfacing mixture. Their results showed that the stamp sand and acrylonitrile styrene acrylate waste mixtures have better moisture susceptibility and rutting resistance than the standard asphalt mixtures 17 . Solving the world's plastic pollution crisis is one of the objectives of circular economy.…”

One of the objectives of the circular economy is solving the world’s plastic pollution crisis and recycling of materials by ensuring less waste. The motivation of this study was to demonstrate the possibility of recycling two types of wastes with a high risk of pollution, such as plastic based polypropylene and abrasive blasting grit wastes in asphalt roads. The effects of adding together polypropylene based microplastics and grit waste in asphalt mixture for wear layer performance have been shown in this study. The morphology and elemental composition of the hot asphalt mixture samples before and after freeze–thaw cycle were examined by SEM–EDX and the performance of the modified asphalt mixture was determined with laboratory tests including Marshall stability, flow rate, solid–liquid report, apparent density, and water absorption. A hot asphalt mixture suitable for making wear layer in road construction, containing aggregates, filler, bitumen, abrasive blasting grit waste and polypropylene based microplastics is also disclosed. In the recipe of modified hot asphalt mixtures were added 3 proportions of polypropylene-based microplastics such as 0.1%, 0.3% and 0.6%. An improvement of the mixture performance is shown at the asphalt mixture sample with 0.3% of polypropylene. In addition, polypropylene-based microplastics are bond with aggregates from mixture well, so the polypropylene-modified hot asphalt mixture can effectively decrease the appearance of cracks during sudden temperature changes.
