Chipseal - Wikipedia
Chipseal (also chip seal) is a pavement surface treatment that combines one or more layer(s) of asphalt with one or more layer(s) of fine aggregate. In the United States, chipseals are typically used on rural roads carrying lower traffic volumes, and the process is often referred to as asphaltic surface treatment.
Chip Seal Stone & Sand - All States Materials Group
Chip seals are suitable for all roads from rural to high traffic volume highways. Stone seals give the best, most durable friction, and sand seals can fill small cracks and voids. Chip seals may also be used on low-traffic, well-graded gravel roads as a first asphalted surface. For preventive maintenance, the pavement to be sealed should be ...

Ergon Cape Seals Equals Extra Value - ergonasphalt
Scrub seals have been proven to provide exceptional benefits both as stand-alone treatments and as part of a combination. The scrub seal is similar to a chip seal except the emulsion contains a rejuvenator, and the addition of a scrub broom pulled behind the emulsion distributor makes it a more suitable application for addressing mass cracking.
NCHRP - Transportation Research Board
A poll of experienced personnel was conducted to (1) determine the extent of use of chip seals on high volume pavements, (2) determine materials, design methods, procedures, performance, etc., where chip seals are used, and (3) understand and quantify the effects of various factors on chip seal performance.

Chip Seal Treatment Types
A chip seal serves to seal the narrow cracks, help bind together cracked pavement, provide a wearing (driving) surface, and protect the underlying pavement structure. Chip seals used as interlayers serve to retard reflective cracking which develops from the bottom of the pavement structure towards the top.

Long term pavement performance studies have shown that chip seals are one of the most cost-effective methods of pavement preservation for all types of roads, from gravel county roads to high volume interstate pavements.
Chipseal - Wikipedia
A chip-seal-surfaced pavement can optionally be sealed with a top layer, which is referred to as a fog seal or enrichment. The introduction of polymer-modified bitumen and emulsion binder has increased chipseal's ability to prevent crack reflection and improve stone retention by improving the properties of the bitumen binder.
