  • Description:
    Dust produced on seasonal road construction sites in Alaska is both a traffic safety and environmental concern. Dust emanating from

    unpaved road surfaces during construction severely reduces visibility and impacts stopping sight distance, and contributes to the local

    burden of PM 2.5, small particulates that present an important environmental air quality concern. This research aims to assist

    ADOT&PF in developing safe, efficient techniques for short-term dust suppression. Experts believe applying a dust-control palliative

    like calcium chloride, Enviroclean, Durasoil, or EK35 to the unpaved surface during road construction will solve the dust problem. This

    research will gather necessary information to determine when, what type, in what concentration, and how often the dust-control

    palliative should be applied. The amount and size of the dust particles, the time the surface is to remain unpaved, the makeup of the

    unpaved road surface, local environmental conditions, and the availability and cost of the dust control palliatives are factors to consider.

    The project is especially valuable because measurement systems used in other states involve special equipment and/or certification of

    observers, neither of which may be practical in Alaska with our remote locations and short construction season.
