Recycle Systems (RAP)

Recycling Work Horse

Take advantage of the savings realized through the use of recycled asphalt pavement (RAP) with Astec RAP systems. The systems are offered in a range of configurations, with a variety of conveyors, screens, grizzlies and crushers. The simplest system consists of one bin, a scalping screen and a conveyor that goes directly to the drum mixer.

The RAP system can be portable, stationary or relocatable. Options include bulkheads, wing walls, screens and grizzlies.

Materials separated by a screen can be crushed. Some systems can then separate lumps, break them up, and deliver that material to the drum along with the portions that passed through the screen.

Features & Benefits

  • A walkway behind the bulkhead provides easy access for maintenance.
  • Bin walls are made from 1/4 inch (.635 cm) thick steel plate with reinforced top openings.
  • The very steep side walls of the RAP bins aid free flow.
  • Standard air cannons keep RAP from compressing in the bin.
  • The bin discharge opening is tapered to make it self-relieving.
  • System can be customized with any number of bins.

Run More Rap

All Astec RAP systems have bins that are built to last and specially designed to feed RAP. Customize your system with any number of bins.
  • A walkway behind the bulkhead provides easy access for maintenance.
    Access For Maintenance
    A walkway in-between the bulkhead and collecting conveyors gives you safer access to the back of the bins and conveyors for maintenance.
  • Standard air cannons keep RAP from compressing in the bin.
    Bins Designed Especially For Rap
    Recycle bins are designed for free flow of RAP even with fine RAP in hot weather. The very steep side walls of the RAP bins aid free flow. One end-wall is vertical and the other is angled at 75 degrees. Air cannons are standard and keep RAP from compressing within the bin.

    The bin discharge opening is tapered to make it self-relieving. It is wider than that of cold feed bins and uses a wider belt feeder. Bin walls are made from 1/4 inch (.635 cm) thick steel plate with reinforced top openings.
  • Multiple bins offer opportunity to recycle other materials such as shingles.
    Advantages Of Multiple Rap Bins
    Multiple RAP bins increase the quantity of RAP while maintaining AC content control through RAP fractionation and use of multiple RAP bins. In-line shingle bins offer additional savings opportunities.
  • Astec conveyors and belt feeders for RAP have high-quality features like extra large belt idler rollers and variable speed drive motors.
    Tough Rap Conveyor And Feeders
    Astec conveyors and belt feeders for RAP have the same high-quality features as feed systems for virgin aggregate. Belt idler rollers are extra large and closely spaced for reliability and long service life. Large, variable speed drive motors assure precision control.
  • Make RAP more usable by breaking the large pieces with a horizontal shaft impactor.
    Break Rock And Hard Rap
    A Telsmith horizontal shaft impactor (HSI), can be used for breaking the asphalt bond between aggregates in hard pieces of RAP.
  • Astec works with its sister companies to design large-scale RAP processing plants.
    Recycle Plants
    Large plants for RAP and roofing shingle processing are available. Astec works with its sister companies KPI-JCI, Astec Mobile Screens and Peterson Pacific to custom-design these plants for each application.
