The alternatives available in street maintenance can take various forms <br />including pot hole patching, crack sealing, sealcoating, bituminous overlay, mill and overlay, <br />mill and patch, cut and patch, and concrete curb repair to name a few. Public Works has <br />typically provided the labor on maintenance projects when the scope fell within the bounds of <br />the expertise and equipment available to the department. For those maintenance projects that <br />require specialized skills or equipment not available to Public Works we contract for those <br />services. <br /> <br />Sealcoating or chipsealing has been one of the staples of pavement maintenance for many years. <br />A relatively new pavement distress called stripping has been observed in bituminous pavement <br />throughout Minnesota. General consensus among bituminous engineers is that sealcoating is the <br />cause of stripping. In response to this many cities across the metro area have curtailed <br />sealcoating as a maintenance practice until more is known about the relationship between <br />sealcoating and stripping. Arden Hills Public Works has followed suit and suspended any <br />sealcoating until there are more answers on this topic. <br /> <br />Discussion <br /> <br />Many of the streets throughout the city have been reconstructed though a Pavement Management <br />Project. The city has had a fairly regular schedule of reconstruction projects every one to two <br />years for the past 16 years. During the course of these projects one comment we get from <br />residents is “if the city maintained our street, we would not have to reconstruct it and pay the <br />AGENDA ITEM –8A <br /> <br /> <br />MEMORANDUM <br />
