Description
Annual Minnesota Department of Transportation State Aid Office reports, cost estimates, and interviews were used to determine a typical county spending history for low volume roads. It was found large initial costs for bituminous roads (HMA), but the ongoing routine annual maintenance activity in later years was less costly than for gravel. The graph of cumulative maintenance costs verifies that annual maintenance costs/mile for a gravel road increase with traffic volume.
