- Pavement Repair
The contracting company is required to replace the pavement cut with a cross section of the road exactly as it currently exists in type, thickness, and material of pavement, with an additional six inches of stone underneath the existing cross section. All granular or aggregate base is to be replaced with aggregate base meeting 21AA specification or equal as approved by the City engineer.
The limits of the pavement cross section repair will be two feet greater than the limits of excavation.
If this limit falls within an additional two feet of an existing joint, full depth crack, or an edge of metal, the limits of the cross section repair will be expanded to include this. Therefore if any joint or crack is within four feet of the limits of excavation, the pavement repair will be moved out to include the joint or crack.
The longitudinal joint of the repair must fall on the centerline between two lanes, or along the centerline of a lane of travel. The only acceptable location for a longitudinal joint is on the centerline of a lane of travel, or between two lanes of travel. All work can be superseded by the recommendation of the City engineer.
All existing sub-base and aggregate base must be compacted to 95% of the modified proctor.
All existing utilities unearthed, encountered, or touched during excavation will be referred to each appropriate agency for inspection before backfilling.
All excavated material will be hauled away. All backfill will be class II granular material. All backfill will be compacted in appropriate lifts to 95% of the modified proctor.
Asphalt pavement repairs shall be sealed with polymer modified overband crack seal as per 2003 MDOT specification 505. All materials shall meet the requirements of 2003 MDOT specification 904 or better.
Concrete pavement repairs shall be sealed with hot poured rubber per 2003 MDOT specification 602 and 603. Materials shall conform to 2003 MDOT 914 or better.
