RECYCLING

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.

  • Less impact on natural resources (fewer oil and aggregate requirements)
  • Reduction of expensive storage facilities
  • CO₂ reductions

 

RAP Cold Addition into the Mixer

  • 25-40% of RAP utilisation possible, depending on system, mix temperatures and moisture content
  • Inexpensive, straight-forward system
  • Low maintenance
  • Possible to retrofit on all plants
  • RAP and aggregates dosed separately into pug mill
  • Good combination with low temperature mixes

RAP Cold Addition into the Dryer

  • 40% of RAP utilisation achievable
  • Easy to retrofit on most plants (with some adjustments on hot elevator chute and hot mineral bins)
  • Can be combined with cold RAP system for greater flexibility during plant operation

RAP Warm Addition with Counterflow RAP Dryer

Low bitumen damage
  • No radiation heat
  • Gentle heating of RAP
High efficiency
  • Low exhaust temperature
  • High RAP temperature
Low emissions
  • Indirect heating
  • Homogenous heat distribution
  • Recycling rates of up to 100% are achievable
  • Enhances chances of approval by governmental agencies
  • Recipes are more flexible as there is no need to overheat the minerals
