Maintenance of Bituminous Roads:

The common defects noticed in a bituminous road are :

potholes
cracks
rutting
corrugations
shoving
stripping and loss of aggregates
edge breaking
loss of riding quality
bleeding or fattened surface
loss of skid resistance
oxidation of bituminous surface

Potholes are repaired by cutting the damaged area to a rectangular shape, applying a tack coat and filling the area with premixed material and compacting. The premixed material is either produced with heated bitumen or preferably a cold mix made with emulsion.
