A pavement is smooth surface or matelled structure built to carry the traffic load under climate conditions.
Why pavement Needed?
A smooth structure is provided for
- The natural earth surface cannot support the modern heavy wheel loads.
- The natural earth surface cannot provide an adequate smooth wearing surface.
Therefore a constructed pavement distributes the wheel load sufficiently and provides a necessary smooth wearing surface.
Road PV are generally classified into two types:
- Flexible PV
The pv which have very low flexible strength and are flexible in their structural behavior under the wheel loads are called flexible PV.
- Rigid PV
They are hard in nature are are made to take heavy loads, mostly such kind of Pv’s are made of concrete, reinforced cement concrerte.
