For a standard lane 12-feet wide and 1 mile long, what would be the cost per-lane mile of pavement?
Cost per lane-mile per inch depth are:
Asphalt = $39,352.50
Base = $15,840.00
Subbase = $2,656.50
If an alternative base material is available for $5,791.50 per lane-mile per inch depth, to use it, the minimum depth for asphalt has to be increase to 6 inch with no change of base and subbasedepth. What will be the total cost per lane-mile per inch depth? If this design can extend the pavement life to 25 years (Normal life is 20 years), which design would you recommend?
