Effects of nano-particles on cold recycled asphalt ...

2021-5-17  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.
