"MDOT's Highest Priority is the Preservation of (the) Current Highway System…."

PREVENTIVE MAINTENANCE is the planned treatment of existing highways and roads that
protects the pavement, decreases the rate of deterioration and adds 5 to 10 years to the service life of the pavement. Compared to rehabilitating or reconstruction of a road, preventive maintenance
of roads that are in fair to good condition has proven through studies to be very cost effective.
