Reclamation road resurfacing

New base materials exit the reclamation machine.
Recycled pavement and base materials exit the reclamation machine.

The Hwy 238 resurfacing project will use a construction process called Reclamation.

Crews grind and mix the old pavement surface with the existing gravel and then place and compact the recycled (reclaimed) pavement materials. A new layer of blacktop is then paved over the reclaimed surface.

In the long run this process saves money. It provides a longer lasting pavement life than a typical mill and overlay resurfacing project. Fewer, if any cracks, will appear in the new road surface with this process.

Rehabilitation Work on Hwy 65 Mora to Woodland

  1. A water tanker feeds water into the reclaim machine to keep the grinder cool and aid in the compaction of the recycled material
  2. A grinder with diamond head teeth, grabs, chops and grinds the blacktop road surface and the below gravel base
  3. Ground up materials travel by conveyor belt to a screened grinder that keeps oversize materials from entering the newly recycled base materials. The reclaimed materials are then placed back onto the existing road surface
  4. A grader smoothes out the new base materials and a compactor packs down and densifies the road base
  5. A new layer of blacktop is paved on top
