Recycled asphalt pavement (RAP) technology

Atmos’ patent-pending HyRAP® manufacturing process and rejuvenating oil are a ground-breaking avenue to producing a high-quality asphalt pavement utilizing up to 100% recycled asphalt pavement (RAP) for city and county roads, local streets and parking areas.

We offer:

  • Proprietary technology
  • Innovative RAP plant engineering design
  • Technical support in structuring effective mix designs
  • A rejuvenating oil which allows manufacturers to achieve 100% pavement reuse

HyRAP is a lower-cost, more accessible substitute for some key asphalt inputs. It performs just as well as a virgin mixture but costs far less, reducing overall road building costs.

Even greater environmental and financial impact is possible when Atmos HyRAP is coupled with our proprietary asphalt pavement recycling process.

Game-changing HyRAP plant design

Ever since manufacturers first began recycling asphalt pavement, they’ve chased an elusive milestone: 100% usage of RAP.

Until now, it hasn’t been possible. The imbalance of RAP generated versus consumed has resulted in RAP piles continuing to grow. Perfectly reusable RAP is forced to be landfilled or is resting in unsightly mountain-sized stockpiles.

Today, Atmos Technologies offers a commercially proven patent-pending recycled asphalt pavement (RAP) process that allows manufacturers to use 100% recycled asphalt pavement in their mix designs.

100% RAP processing is only possible thanks to our proprietary HyRAP® equipment design and rejuvenating oil.

The use of RAP is not new. In traditional operations, the mix design consists of mostly virgin aggregate and virgin asphalt binder. There are common issues around quality and pollution control when trying to utilize high percentages of RAP.

Higher percentages of RAP typically result in stiffer asphalt, poor workability in the field and a finished product more prone to brittleness and cracking. Due to the presence of asphalt binder in the RAP aggregate, blue smoke is generated and is a limiting factor for RAP used in a conventional plant.

Our process eliminates these quality impediments by carefully managing the RAP input and the mix design parameters. Crucial to the mix design is the incorporation of our uniquely developed rejuvenating oil.

Consider the many environmental benefits of 100% recyclability:

  • The aggregate in RAP is infinitely reusable, reducing reliance on new quarrying
  • By mitigating the transportation of virgin aggregate, emissions and truck traffic are significantly reduced
  • RAP piles are dramatically reduced, eliminating unsightly eyesores and the black dust they generate which harms air quality
  • Burying old pavement in landfills is no longer necessary, extending the longevity of finite permitted trash disposal space

According to the National Asphalt Pavement Association (NAPA), “RAP usage during the 2019 construction season is estimated to have reduced the need for 4.5 million tons (24 million barrels) of asphalt binder and more than 84 million tons of aggregate.

A joint NAPA-Federal Highway Administration survey reported that the industry reclaimed 97 million tons of RAP for future use, saving enough landfill space to fill up the dome of the U.S. Capitol 1,223 times.

Our flexible asphalt recycling plants can be designed for permanent placement in traditional sites or configured for portable recycling at locations closer to the RAP source.
