Cold Mix Asphalt Using Waste Materials: A Review on Performance and Sustainability

Abstract Road construction uses large amounts of energy, raw materials, and money. Hot mix asphalt (HMA), the most common road material, requires heating aggregate and bitumen to temperatures of 150 to 190°C, which consumes significant energy and produces greenhouse gas emissions. Cold mix asphalt (CMA) is a type of road material that is produced and laid at room temperature without heating, using bitumen emulsion or foamed bitumen as the binder. CMA offers important environmental and cost benefits but has traditionally been limited to low-traffic roads because it tends to be less stiff and durable than HMA. In recent years, many researchers have studied the use of waste materials such as recycled tyre rubber, fly ash, bottom ash, recycled concrete aggregate, plastic waste, waste glass, steel slag, reclaimed asphalt pavement, and coal mine waste in CMA mixtures. Adding these waste materials can improve the mechanical performance of CMA while also providing environmental benefits by diverting waste from landfills and reducing the use of virgin materials. This paper reviews the published journal research on the use of waste materials in CMA, covering mechanical performance, binder properties, curing behaviour, durability, moisture resistance, and environmental and economic benefits. The review shows that waste-modified CMA mixtures can achieve indirect tensile strength (ITS) values of 410 to 610 kPa, Marshall stability of 7.5 to 12.5 kN, and tensile strength ratios (TSR) of 78 to 91 percent, which are comparable to or better than conventional CMA without waste materials. Environmental analysis shows CO2 savings of 8 to 42 percent and energy savings of 10 to 45 percent depending on the waste material and replacement level. Research gaps and future directions are also discussed.
