Chip overlay
WebA chip seal is about one fourth to one fifth the cost of a conventional asphalt overlay. By extending the time between asphalt overlays, chip seals result in lower costs over the long term. By placing a chip seal sooner than an asphalt overlay would be placed, the traveling public benefits from roads maintained in better condition. WebModern chips can have up to 100 layers, which all need to align on top of each other with nanometer precision (called 'overlay'). The size of the features printed on the chip varies depending on the layer, which means …
