What is Chip Sealing?

Chipseal is a pavement type that combines one or multiple layers of asphalt with fine aggregate. This type of pavement is typically seen on rural roads with lower traffic volumes. Chip Sealing is created with the same ingredients as asphalt concrete paving. However, the difference is that it introduces the key aggregate that forms the "chips." These chips are heavily compacted within asphalt surfaces to provide an even, seamless finish.

• Chip seals provide ODOT
• Chip seals cost about one fourth to one fifth the cost of a conventional asphalt overlay.
• With extending the time between asphalt overlays, chip seals result in lower costs.
• Place chip seal sooner than an asphalt overlay, the traveling public benefits from roads maintained in better condition.
• Chip Seals eliminate the need to crack seal as well as enhances safety with a good skid resistance.
• These seals also proven to be an effective moisture barrier for e underlying pavement. This helps protect against water intrusion.
• They help prevent deterioration.
• ODOT has successfully used chip seals for over 25 years in maintaining state routes.
• They are only used on roads that have less than 2500 vehicles per day.
• Chip seals virtually eliminate black ice.
• Chip seals re-seal cracks by flowing back together in hot weather.
