Cold recycling in plants of old asphalt pavements

2019-8-9  Old asphalt materials can be recycled using cold, warm or hot production methods, and the addition of new binder, asphalt mixture, water or mineral aggregate in the old asphalt can be performed either in the plant or on site. Recycled asphalt can be used for wearing courses, basecourses or roadbases. Cold and warm methods are mainly intended for roads with low or medium traffic volumes, while hot recycling is also suitable for roads with high traffic volumes. In cold and warm recycling, the proportion of recycled asphalt may be up to 100%, while in heated plant recycling the proportion may be 10-40%. In Sweden, a total of just over 1 million tonnes of old asphalt pavements is recycled
