single chip seals (one application of binder followed by one application of aggregate) and 5 to 7 years for double chip seals (one application of binder and aggregate followed by a second application of binder and aggregate) (NHI 2013). There are a number of factors that can influence chip seal performance. These factors
• Sealing over poorly constructed pre-reseal repairs. • Cold binder. • Fretting of the upper chip layer of a two coat seal. • Dirty chip (Figure 12-4). • Binder oxidation. • Stop-start traffic, particularly on up or downhill sections of roads, e.g. rubbish trucks on urban streets. • Heavy braking and acceleration.

Chip Seals (or seal coating, BST, Bituminous Surface Treatment) is the application of a special protective wearing surface to an existing pavement. Why chip seal? To keep water from penetrating the road structure on paved surfaces. To fill and seal cracks and raveled surfaces of old pavement.
Chip Seals Understanding Chip Seals • Benefits and Limitations • Design and material selection • Proper construction methods/techniques • Variations • Types of failures and causes "Chip seal is the application of an asphalt binder to a pavement surface which is covered by a layer of one-sized, preferably crushed, cubical, aggregate"
Since a roadway is rarely closed to traffic for the chip seal application, a smooth flow of traffic through the work area is required. Driving slowly, not turning sharply, or braking quickly or spinning tires is crucial for the fresh chip seal to properly set and cure. Until a road is broomed, the lower, 25 mph speed limit needs to be observed ...
A seal coat is an application of a layer of asphalt binder covered with a layer of aggregate applied to an existing paved surface. TxDOT spends close to $180 million annually maintaining 197,500 lane miles of roadway, and seal coats are a very important part of TxDOT's preventive maintenance program. TxDOT state forces place approximately ...
