• Abstract:
  The Maine Department of Transportation (MaineDOT) is responsible for maintaining approximately 8300 ; miles of public highways. Maintenance of these highways consists of rehabilitation or reconstruction ; when the road has deteriorated to an unacceptable level. With economic fluctuations and ever increasing ; traffic levels, this policy does not effectively address the needs of the highway system when maintenance ; is necessary and creates a backlog of deficient highways. ; To reduce this trend, many states have adopted the policy of Pavement Preservation. This policy consists ; of applying preventative maintenance to the roadway before it has deteriorated to an undesirable level, ; which maintains structural integrity and extends service life of the pavement. Length of time between ; costly rehabilitation is increased, reducing the cost of maintaining the highway system. Several states ; have reported that they were able to improve the overall condition of their highway system after ; implementing this approach and that every dollar spent using preventative maintenance could save up to ; six dollars in future spending. ; Maine has two types of roads: “A” roads, which are built to state standards and “B” roads, which are not. ; Pavement Preventive Maintenance (PPM) can be used effectively on “A” roads to extend service life. ; Examples of PPM treatments include Crack Sealing, Hot Maintenance Mulch, Thin Overlays, and Micro-Surfacing. Crack Sealing prevents water and debris from entering cracks in the pavement by sealing them ; with a rubberized material. Hot Maintenance Mulch is a hot mix asphalt pavement with little or no ; crushed aggregate and is typically used on “B” roads. Thin Overlays are dense - open graded Superpave ; mixes, with or without recycled asphalt pavement incorporated into the mix, that are typically used on ; “A” roads. Micro-Surfacing is a thin layer of a mixture of polymer-modified asphalt emulsion, mineral ; aggregate, mineral filler, and water. ; This report will examine the application of Micro-Surfacing to extend the service life of two projects in ; Aroostook County.
