How does the maintenance cost per mile for portland cement concrete pavement compare with other types?
Several years ago a study based on records kept by the highway departments of 24 states showed an annual maintenance cost of $161.99 per mile for portland cement concrete pavements, compared with $219.52 per mile for the next best (bituminous concrete--rigid base) from the standpoint of maintenance cost. Other types of bituminous surfaces showed maintenance costs as high as $350 per mile.
