  • Investigation of a nonwoven fabric as a reinforcement for gravel paved roads

    Creator:
    Kelsay, Harry Stanley
    Abstract:
    Full scale test roads combined with a theoretical analysis were used to evaluate the benefits of incorporating a fabric as a base course support material for gravel paved roads. One material, a synthetic, nonwoven, polypropylene fabric was used in this investigation. This fabric was used on top of the subgrade...

  • Reducing sediment production from forest roads during wet-weather use

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...
