Chip seal is a pavement surface treatment that combines a layer(s) of asphalt with a layer(s) of fine aggregate. In the United States, chip seals are typically used on rural roads carrying lower traffic volumes, and the process is often referred to as "asphaltic surface treatment". In Australia and New Zealand, chip sealing is referred to as a "sprayed seal" or "tarseal" and is used on a larger percentage of roads, both rural and urban.

Chip seal is cheaper than resurfacing an asphalt concrete or a Portland Cement Concrete pavement, but not as long lasting. In some states of the United States, chip sealing is used in conjunction with new road construction to make the road bed more durable and longer lasting.

Chip seals are constructed by evenly distributing a thin base of hot bitumen or asphalt onto an existing pavement and then embedding finely graded aggregate into it. The aggregate is evenly distributed over the seal spray, then rolled into a smooth pavement surface. A chip seal surfaced pavement can optionally be sealed with a top layer which is referred to as a fog seal or enrichment.
