Public Works Superintendent Riemer stated the residents do not want to pay for the sewer or <br />water assessments and the City does not want to reconstruct a road and then in ten years have to <br />tear it out to install utilities. He agreed that is one of the biggest questions holding it up. <br />Councilmember Elvig stated that will be a dilemma for many of the reconstructed roads and . <br />whether to add concrete curb and gutter. He noted the City will need to establish a policy. <br />Acting Mayor Backous asked whether staff's recommendation is to reconstruct to a 9 -ton <br />standard even for residential streets. <br />Public Works Superintendent Riemer answered in the affirmative since the roads will hold up <br />longer. <br />Acting Mayor Backous asked if staff recommends curb and gutter because it extends the life of <br />the roadway by creating sides to hold up and protect the blacktop edges. <br />Public Works Superintendent Riemer confirmed that is the case. <br />Interim Engineer Nelson stated staff wanted to present information for the Council's discussion. <br />He described the materials of which blacktop is comprised and provided a presentation on <br />pavement maintenance. <br />Councilmember Elvig asked whether RV sunlight rays also deteriorate blacktop and if the use of <br />granite chips prevents deterioration. <br />Interim Engineer Nelson stated that is correct and the layer of oil prevents RV sunlight from <br />deteriorating the blacktop. He continued presentation of pavement maintenance by describing <br />how moisture undermines the aggregate road base, and how patching, crack filling, sealcoating, <br />and overlays can extend the life of the pavement. Interim Engineer Nelson reviewed the costs <br />for pavement rehabilitation and number of years it would extend the life of the road. He <br />indicated that Ramsey has good subsurface soils and explained how regular maintenance can <br />extend the pavement and avoid the most costly method, reconstruction. <br />City Administrator Ulrich asked about the use of geo- textile fabric underlayment to extend <br />pavement life. <br />Interim Engineer Nelson described how geo - textile fabric underlayment is used and explained <br />that every time he has looked at the costs, he has found the money would be better used to <br />increase the depth of the subsurface or inches of blacktop. In addition, underlayment can cause <br />problems when the road is reconstructed. <br />Councilmember Riley asked when crack sealing is done. <br />Public Works Superintendent Riemer stated the City only does crack sealing just prior to <br />sealcoating. <br />City Council Work Session / March 19, 2013 <br />Page 3 of 16 <br />
