Why American Highways Cost Millions Per Mile. Road Construction & Heavy Machinery

America spends millions of dollars building a single mile of highway—but the asphalt is often one of the cheapest parts. This documentary reveals what drivers are really paying for: massive earthmoving machines, precision grading, extreme soil compaction, recycled asphalt, advanced asphalt plants, precast concrete pavement, slipform paving, giant bridge girders, bridge decks, drainage systems, expansion joints and highway maintenance. From projects in Colorado, Washington and Texas to Arizona, Illinois and Ohio, see how heavy machinery, civil engineering and carefully coordinated construction systems create the highways millions of Americans use every day.
