Abstract:Environmental concerns have changed the way Oregon Department of Transportation (ODOT) controls roadside vegetation. Additionally, rules to control noxious weeds and promote natural vegetation have prompted many agencies to adopt an Integrated Vegetation Management (IVM) Program.
A prototype roadside infrared vegetation control unit, manufactured in Eugene, Oregon, applies intense heat (approximately 1500ºF / 800ºC) to unwanted growth. It uses liquid propane fuel to heat a radiating unit made of steel. The bottom of the deck travels 2 to 4 inches above the ground, allowing the heat to radiate without the equipment touching the vegetation.
