- Total resurfacing area: 673 linear feet by 17 feet wide.

- Compact and grade surface to provide a crown or appropriate cross slope for drainage.

- Tie resurfaced areas into adjacent pavement smoothly.

- All work shall conform to Maine DOT or FHWA standards for materials and installation.

Washed-Out Section Repair and Paving

- Excavate and remove all loose and unsuitable material in the washed-out area.
