In air at standard conditions, the speed of sound is 340 m/s (1130 ft/s, 770 mph). The speed of sound is fast enough that the sound created by a closeby event will seem to be coincident with the event. On the other hand, sound is slow enough that a delay is detectable when a source is far away.
The asphalt concrete pavement course consists of aggregate, and asphalt binder mixed in a central plant and spread and compacted on a prepared surface. The requirements of Item 441 apply, except as modified by this specification.
Asphalt Concrete Repair. The vast majority of potholes and pavement failures can be traced to water entering the base and subgrade through joints that have not been crack sealed in both concrete and asphalt. In most pavements, the base, subbase or subgrade consists of a material that loses its loadcarrying capacity when wet.
