The phenomena in which the segregation of bitumen and aggregates takes place in the presence of moisture is called 

Explanation:

Streaking:

• It is the loss of aggregate from a surface dressing in streaks running parallel to the pavement centerline.
• Streaking is caused by a faulty operation of spraying equipment.
• This streaking can also be formed as a result of applying the bituminous Binder at too low-temperature, at which bitumen is not fluid enough to fan out properly from the nozzle on the spray bars.

Slippage:

• Slippage is relative movement between the surface layer and the layer beneath. It is characterized by the formation of crescent-shaped tracks that point in the direction of the thrust of the wheels on the pavement surface.
• This does not mean that the track invariably point in the direction the traffic is going. For example, if brakes are applied on a vehicle going down a hill the thrust of the wheels will be pointing uphill. The cracks in the case will, therefore, point uphill.

Stripping: 

• This defect is characterized by the separation of bitumen adhering to the surface of the aggregate particle in the presence of moisture. This may lead to loss of Bond and subsequently to loss of strength and materials from the surface.

Rutting: 

• It is the longitudinal depression caused due to the movement of most of the vehicles on same path and also due to higher percentage of heavy loads. This depression is formed due to excessive shear force at a section.
