[holding answer 30 November 2009]: The estimated cost per mile of resurfacing each lane of concrete pavement on a motorway using quieter surfacing materials ranges between £200,000 and £1,900,000 at today’s prices. Accurate cost estimates can only be obtained once a scheme’s detailed design has been undertaken, as this will depend on the type of treatment required and associated site specific requirements. The higher costs would only be incurred where roads constructed to old design standards (i.e. before 1987) were resurfaced, so these are becoming increasingly rare.
