Types of pavement structures

  • Pavements, in general, can be classified in two major categories: concrete pavement and bituminous pavement.
  • Concrete pavements are generally called rigid pavements and bituminous pavements as flexible pavements.
  • There could be some other types of pavements which are neither rigid, nor flexible, for example, block pavement, composite pavement.
    A  Pavement is a multi-layered structure. The layers are placed one over other. In general, the strengths of  the layers decrease from top towards bottom except some special situation like inverted pavement. The terminologies used to identify various layers of bituminous and concrete pavements are identified in Figs. 1 and 2
