RECLAMATION
The pavement reclamation process removes a faulty asphalt surface, grinds it up, and replaces it back down as the subgrade of a new asphalt surface. This process reduces or eliminates hauling costs and dump fees. It also reduces the need for virgin aggregates.
Once the sub base is thoroughly compacted, a new asphalt surface would be applied typically consisting of a base course layer, of 2- -4 inches and a surface course layer of 1 - 2 inches. Specifications for reconstruction are always determined by soil conditions, anticipated traffic loading, and desired design life of the pavement factored in with budget constraints in mind.
The Process:
- Crush the surface using a pavement reclamation machine.
- Grade the mix with a motor grader.
- Spread lime over the graded mix.
- Inject water into the lime mix to ensure the correct density.
- Grade sub base for proper water flow.
- Compact stone base with power-driven vibratory rollers.
- Install geotextile water-resistant fabric, if necessary.
- Install two lifts of asphalt.
- Lift 1: Large aggregate base mix. Compact.
- Lift 2: Small aggregate surface mix. Compact.
- Lay out and paint pavement markings.
- Allow the new paint pavement markings.
- Allow the new pavement to cure.
- Your lot is new again.
