Pavement design using recycled asphalt

Pavement design using hot or cold recycled asphalts may be carried out by the same methodologies as the ones used for pavements with virgin hot or cold asphalt layers, provided the mechanical properties of the recycled materials are considered. 

In addition to the pavement design methodologies covered in Chapter 12, the pavement design method developed by Merrill et al. (2004) specifically for pavements with cold recycled materials may also be used.
