Cold recycling in plants of old asphalt pavements

Therefore, cold recycled pavements should not be laid very late in the year and the temperature during laying should be over +5°C. The pavers and rollers used for cold recycled asphalt are generally the same as those used for newly manufactured cold asphalt. Suitable layer thicknesses may be 80-120kg/m2.
