Cost Benefits
- 75% faster construction than traditional mill & resurface treatment, which reduces delays, inconvenience to travelling public, and labor costs.
- Approximately 50% reduction in life-cycle cost compared to traditional mill & fill treatment.
Factors that may Impact Cost
- Traffic staging: It is more effective to pave one lane the full job length, than to do both lanes to the same point each day.
- Urban work vs. rural work: catch basins and intersection control on urban jobs can add to cost.
- Night work: Night work costs more for labor, but has fewer traffic disruptions.
- Letting date vs. completion date: Number of working days affects cost.
- Raw material pricing and accessibility/mobilization: emulsion and aggregate cost variables.
- Number of contractors in region.
Decrease Cost Without Affecting Quality
- Early letting closing, ideally October through December for the following year’s work.
- Clear, constructible specifications, fully understood by inspection staff.
- Longer lane closures so the process can proceed without waiting to reopen a lane.
- Consistent annual Micro Surfacing program, such that contractors are comfortable investining in equipment and people.
