Specifications include, but are not limited to: As far as possible, all roads will be overlaid variable widths and from 1-1/2" to 2-1/2" thick asphalt. Some of the subdivision roads will have to be less than 20 feet, but as much width as possible will be obtained. Where warranted, some roads will get more than 22 feet of width. Numerous roads will receive extra thickness as needed for strength and/or leveling. The Engineer reserves the right to lay asphalt on each road as work progresses to meet field conditions without any change in unit prices. The Contractor will blade shoulders and perform any other work necessary to prepare for paving. There is a price in the proposal for the Contractor to do all digging out and patching. The Contractor will be required to clean and tack the old asphalt before the overlay is started and this will be an absorbed item. In some areas, a leveling coarse may be needed ahead of the overlay and this asphalt will be paid for at the same unit price per ton as the overlay on the road. All asphalt used in patching will be a separate bid item.
