The use of reclaimed asphalt, or recycling, has become a necessity. Governments increasingly want the reclaimed asphalt from old roads re-used in an effort to be more environmentally friendly. Recycled asphalt (RA or RAP) also can provide you with cost savings on several fronts.
Ammann provides several options to help your recycling and cost-saving efforts. Regardless of the system you choose, modern Ammann plant technology will provide a quality recycling process and product.
