Chanhassen Explains Road Repair Strategy in Educational Series
The City of Chanhassen has released an educational video explaining its pavement management plan, focusing on full depth reclamation as a key road repair technique for the city's 119 miles of streets.
Full depth reclamation, or FDR, involves grinding up existing asphalt and mixing it with the top portion of the aggregate base to create a new foundation layer. New asphalt layers are then installed on top, with excess recyclable material hauled away for use elsewhere.
The city uses this construction method when existing pavement shows significant deterioration and scores below 60 on the Overall Condition Index, a zero to 100-point scale used to rate road health. The city reviews and grades all roads every three years, prioritizing work based on available funding and condition scores.
According to the video, full depth reclamation is more expensive than mill and overlay techniques but less costly than total reconstruction, which requires additional improvements. The method allows the city to recycle existing materials while extending road life.
The educational video is part of a pavement management series available to residents. Additional information about city projects is available at chanhassenm.gov/projects.

Full depth reclamation or FDR involves grinding up a road's existing asphalt and mixing it with the top part of the aggregate base to create a new base layer.
We use this construction technique when the existing pavement shows signs of significant deterioration and generally scores below a 60 on the overall condition index a zero to 100 point scale we use to rate a road's health.
Although this method is more expensive and extensive than the mill and overlay technique it avoids the more costly total reconstruction which involves various additional improvements.
