Abstract
Methods are described for maintaining unpaved roads. The methods include applying an aqueous composition to a section of an unpaved road (such as a mine haul road in a mine). The aqueous composition includes from 5 to 10,000 ppm of a synthetic polymer in water, and may be applied periodically. The synthetic polymer may be compatible with chemical processes employed by the mine, and the method may also include subsequently mining the section of the mine haul road.
