Description

Continuous and Quick. Hot In-Place Recycling

Encore® hot in-place recycling uses an innovative emulsion specially developed for the process. The emulsion includes rejuvenator oils for bringing the aged asphalt back to life and Stylink® polymer modified asphalt for added adhesion, elasticity, temperature resistance and durability.

Hot in-place recycling is a continuous process performed with a self-contained train of equipment. With Encore, approximately 1 to 1½ inch of the existing pavement surface is heated, scarified, treated with rejuvenating emulsion, milled, mixed, replaced on the road with a vibratory screed and compacted. A surface course or treatment may be applied immediately after the recycling. Or, if it is a better fit for construction scheduling, the surface may be applied later. During hot in-place recycling, only the lane being recycled is closed, and it can be reopened quickly after the compaction is completed.

Features/Benefits

  • Aged, distressed surfaces replaced with new surfaces
  • Deformations leveled
  • Surface cracking removed
  • Crowns re-established
  • Clearances and curb heights maintained
  • Economically reuses existing materials
  • Can, itself, be recycled
  • Quick construction and immediate traffic return
  • The Encore recycled pavement can be higher quality than the original
    • The rejuvenator oils restore the chemical composition of the oxidized, aged asphalt
    • The process completely coats the aggregate
    • The Stylink polymer modified asphalt improves durability, flexibility, adhesion, strength and resistance to temperature extremes, rutting and cracking
    • Encore mixes have shown 35 percent higher strengths than recycled mixes made with conventional, off-the-shelf emulsions
