Rigid Road or Rigid Pavement
Rigid pavement composed of a PCC surface course. Such pavements are substantially “stiffer” than flexible pavements due to the high modulus of elasticity of the PCC material.
- Further, these pavements can have reinforcing steel, which is generally used to reduce or eliminate joints.
- Because of its relative rigidity, the pavement structure distributes loads over a wide area with only one, or at most two, structural layers.
- This type of pavement can serve 20 to 40 years with little or no maintenance or rehabilitation and often used in urban and high traffic areas.
