The goal for interstate maintenance is to meet or exceed the public’s expectations of a smooth, safe and visually appealing roadway by maintaining interstates with quality in a timely manner.
The Interstate Maintenance Quality Assurance (IMQA) Program has been developed by MoDOT to rate the condition of Missouri’s interstates. MoDOT Maintenance employee expectations for pavements, shoulders, bridges, traffic control, roadside features, roadsides, drainage, Welcome Centers and uninterrupted traffic flow are provided. Elements of primary concern include mainline pavement repair, bridge deck and approach pavement smoothness and ramp and shoulder pavement.
Missouri is divided into six Interstate Corridor Engineer Areas: Northwest Missouri, Kansas City Metro, I-70 Outstate, St. Louis Metro, I-55 Outstate and I-44 Outstate. IMQAs for each Interstate Corridor Engineer Area will contain random samples of approximately
- 1% of the total number of roadway segments
- 10% of the total number of interchanges and
- 10% of the total number of bridges.
Contents
Corridor Engineer Responsibilities
The Corridor Engineer plans Maintenance’s efforts and establishes work priorities. Management of on-call maintenance contracts and ensuring consistencies are additional responsibilities.
Maintenance Superintendent Responsibilities
Scheduling pavement replacement crews work, coordinating work with regional Maintenance buildings and providing quality control are the responsibility of the Maintenance Superintendent. A map of the Maintenance Supertintendent areas is available.
Pavement Repair Crew Responsibilities
The pavement crew is responsible to make minor concrete repairs and minor asphalt repairs that produce a smooth ride and look good.
District Maintenance Responsibilities
District Maintenance will provide temporary traffic control for on-call pavement repair contracts and corridor pavement repair crews. MoDOT will also stripe the roadways and may haul millings.
