Why are some roads sealcoated during the summer and others are not?

The township does not sealcoat all roads each year. Sealcoating is not designed to build up the road bed; it is to keep moisture out and dust minimized. Thus, it is not usually necessary to sealcoat each road each year...once every two or three years is normally adequate. We do check for cracks and deterioration each year, however, and will sealcoat any road that needs it even if it was done the previous year.
