.V.‘ ' , <br />Our reconunendatioii is before the house construction begins that Orono and <br />Independence work together to blade patch die qq;xoximately SOO feet of poor pavement, <br />in the Orono/lndependence section, a^ then spot patch the rest of the road in this <br />section. This is only a temporary solution to get d^ugh the temporary heavy <br />construction traffic time period while the subdivision is being built out. Once the house <br />construction is completed, a longer term pavement rehabilitation project can be <br />dieted on this r^. <br />Blade patching consists of using the road grader to spread the pavement which is ^n <br />compacted with a steel drum roller. For snudler pavement areas, this is more efficient and <br />Ifti expensive than hiring a paving contractor with an aqihalt paver. This work could be <br />completed in a day and will require about 10 truck loads of asphalt at a cost of <br />approximately $3,000. Both cities can provide trucks to haul the asphalt in order to split <br />the costs. This bl^ patching should most likely be sufficient to last during the house <br />construction period as the road previously had 1,000 vehicles per day with some trucks <br />iiHli«itig the rood. If the road does have some areas of substantial pavement breakup <br />ihiring the construction period, we may have to remove the pavement and correct the soft <br />spots in the aggregate base. <br />Once the house construction is conqileted, the 2S0 vehicles per day from the new <br />development, which will be predominately cars, will have a minimal impact on the road. <br />The long term solution for this road will t^ be to complete full depth pavement <br />reclamation and repave Townline Road. Full depth pavement reclamation utilizes a <br />reclaiming machine tiuU pulverizes the existing pavement into an aggregate base type <br />material which is then graded, soft qwts repaired, and paved over. This process <br />elittUnalet the reflective cracking in the new pavement. This is the same process that <br />was used in 1999 on Stubbs Bay Road north of Watertown Road and this pavement is in <br />good condition and will last ftxr many years. <br />I ’ <br />4. <br />f Mi) <br />Page 2 of2 <br />I
