How does the asphalt compare with concrete as far as dollar volume?

It does save taxpayers dollars. In a 3-year analysis conducted by the Florida Department of Transportation, initial construction of an asphalt pavement cost $544,981 to concretes $766,729. After wear and tear and maintenance, the residual value of the asphalt pavement was 203% more than the concrete road. While each road needs to be analyzed based on its own merits, for maintaining roads, the Florida Department of Transportation calculated their routine annual maintenance costs as $132 per lane mile for asphalt pavement and $261 per lane mile for concrete pavement. HMA gives the best return on investment of any paving material. HMA pavements can be cold milled and recycled which saves costly readjustment of manholes, curbs and sewer drains when rehabilitating urban streets.  more
