Effects of nano-particles on cold recycled asphalt properties
Abstract Cold recycling of asphalt is an effective solution to reduce the environmental impacts of pavement construction and operation. This approach reduces the use of scarce resources and fossil fuels, and prevents the spread of greenhouse pollutants in the air. Despite its benefits, recycled asph...

| description | Abstract Cold recycling of asphalt is an effective solution to reduce the environmental impacts of pavement construction and operation. This approach reduces the use of scarce resources and fossil fuels, and prevents the spread of greenhouse pollutants in the air. Despite its benefits, recycled asphalt does have drawbacks, some of which include nibbling, stripping, and less resistance to fatigue. The use of additives can improve the mechanical properties of recycled asphalt. In this research, the addition of Nano-lime, Nano-Alumina, and Nano-clay instead of cement, to bitumen emulsion in recycled asphalt was used to improve the properties of asphalt resilient modulus and fatigue. A comparative method was used to analyze the obtained experimental results. In this study the resilient modulus and fatigue properties of asphaltic concrete were measured. The results show that asphalt fatigue properties and resilient modulus improve significantly with the addition of different Nano-particle percentages. |
