Chanhassen Explains Road Reconstruction Process in Educational Series
The City of Chanhassen released an educational video explaining its road reconstruction process as part of its pavement management plan series. The city manages approximately 119 miles of streets and reviews all city roads every three years to prioritize maintenance and construction based on available funding.
Reconstruction represents the most comprehensive road rehabilitation technique used by the city, involving complete removal and replacement of existing roadways. The process can include replacing asphalt pavement, aggregate base, curb and gutter, and sidewalks or trails if not previously present. Additional infrastructure such as sand subsection, drain tile, and public utilities may also be installed or inspected for replacement during reconstruction projects.
The city typically uses reconstruction when existing pavement shows significant deterioration and scores below 40 on the Overall Condition Index, a zero to 100-point scale used to rate road health. However, other engineering factors may influence the selection process beyond the OCI rating system.
Unlike full-depth reclamation, another rehabilitation technique covered in the city's video series, reconstruction involves more extensive improvements including utility reconstruction, subbase and subgrade replacement, and safety enhancements such as curb and gutter additions. The method is reserved for roads that have reached the end of their life cycle.
The reconstruction process represents a significant investment in Chanhassen's transportation network, with the maintenance and rehabilitation cycle beginning again once projects are completed. Residents can find more information about ongoing projects at chanhassenm.gov/pros.

Chanhasson Pavement Management Plan: Road Reconstruction
▸Meeting Analysis
“reconstruction is when the entire road is completely removed and replaced”
“We use this construction technique when the existing pavement shows significant signs of deterioration and generally scores below 40 on the overall condition index”
“reconstruction is necessary when a road reaches the end of its life cycle this type of repair represents a significant investment in the future of Chanhasson's transportation network”

[0:00] the city of Chanhasson manages
[0:01] approximately 119 miles of streets and
[0:03] their upkeep we review and grade all
[0:06] city roads every three years based on
[0:08] funding we prioritize what roads need
[0:10] work and schedule construction and
[0:12] repairs this is our pavement management
[0:16] plan one technique we use to
[0:19] rehabilitate our city roads is
[0:20] reconstruction reconstruction is when
[0:22] the entire road is completely removed
[0:25] and replaced this can include replacing
[0:28] the existing asphalt pavement aggregate
[0:31] base curb and gutter and sidewalk or
[0:33] trails if not previously present a sand
[0:36] subsection drain tile curb and gutter
[0:39] and sidewalk may be installed during
[0:42] reconstruction public utilities such as
[0:44] sewer and water are inspected for
[0:45] replacement we use this construction
[0:47] technique when the existing pavement
[0:49] shows significant signs of deterioration
[0:51] and generally scores below 40 on the
[0:54] overall condition index a zero to 100
[0:56] point scale we use to rate a road's
[0:58] health although we use the OCI to
[1:00] address road rehabilitation keep in mind
[1:02] that other engineering factors may play
[1:05] a role in the selection process similar
[1:07] to full depth reclamation a technique we
[1:09] covered in a previous video in this
[1:10] series this method is used when roads
[1:12] are in need of substantial rehab unlike
[1:15] a full- depth reclamation reconstruction
[1:17] involves improvements such as utility
[1:19] reconstruction subbase and subgrade
[1:22] replacement the addition of a curb or
[1:24] gutter and other safety improvements in
[1:27] short reconstruction is necessary when a
[1:29] road reaches the end of its life cycle
[1:31] this type of repair represents a
[1:32] significant investment in the future of
[1:34] Chanhasson's transportation network once
[1:36] complete the cycle of maintenance and
[1:38] rehabilitation begins again that's
[1:41] reconstruction the rehabilitation method
[1:43] we use to renew a road when it reaches
[1:45] the end of its life cycle for more
[1:47] information about why we choose certain
[1:48] repair techniques over others an
[1:50] overview of the construction process and
[1:52] less intensive repair techniques make
[1:54] sure to check out the other videos in
[1:56] our pavement management plan series for
[1:58] more information about the projects
