The City of Eden Prairie's annual bituminous overlay and rehabilitation project is underway. The contractor is GMH Asphalt Corporation and the project streets are located generally in the southern portion of the City as indicated on this project map [PDF]. Repair work by City crews within the project area has already started, which includes concrete curb and gutter repair (where concrete curb and gutter is present), storm sewer catch basin and sanitary sewer manhole repairs, and street patching.
The intent of the project is to prolong the life of the street in a cost-effective way, addressing issues before the street deteriorates completely and a much more costly street reconstruction is required. There are no assessments to the adjacent property owners for this project.
The bituminous milling is scheduled to begin in late June or early July. This work includes milling off the top layer of existing bituminous pavement to improve street drainage and remove surface defects. The actual bituminous overlay is placed after the milling and additional repair work has been completed, generally lagging the milling by one to four working days, weather dependent.
Several streets within the project area will receive an “underseal” in addition to the mill and overlay. These areas include Dell Road from Scenic Height Road to Crestwood Terrace and other streets as shown on the project map. The top layer of asphalt will be milled off followed by a chip sealcoat. Once the excess rock from the sealcoat has been swept up, a new layer of asphalt will be placed for the final surface. This process is designed to minimize reflective cracking.
Parking on project streets should be avoided during the milling operation, sealcoat and the placement of the asphalt. Letters to properties adjacent to streets to be worked on will be sent out to residents prior to the work occurring on their street with a more detailed schedule.
Repair work on sections of Mitchell Road from Sorrel Lane to Carmody Drive and Homeward Hills Road from approximately Horseshoe Trail to Tanglewood Drive will also occur as part of this project. This work requires removal of the full depth of the street including the aggregate and asphalt, followed by placement of geotextile fabric and a new street section. This work may require short-term closures of the roadways. Prior to any road closures, appropriate traffic control and detours, if necessary, will be provided.
