  • Abstract:
    The Maine Department of Transportation (MDOT) is responsible for maintaining approximately 14,000

    kilometers 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,

    maintaining the structural integrity and extending the 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

    trying 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 overlay 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.
