Types of Distresses in Concrete Pavements and their Causes ...

The deflection of the slab when loaded may cause pumping, which is characterized by the ejection of water and subgrade (or subbase) material through the joints or cracks in a pavement. As the water is ejected, it carries particles of gravel, sand, clay, or silt with it, resulting in a progressive loss of pavement support that can lead to cracking.

Causes of Failure of Pavement Flexible Pavement Failure ...

The pavements are broadly classified into two categories, namely, flexible pavements and rigid pavements. There are specific causes that contribute to the failure of each type and they will be now briefly described as follows: (1) Failures in flexible pavements (2) Failures in rigid pavements. Here we briefly discuss about flexible pavement ...

Any plant roots growing under the pavement too can cause bumps in the pavement. The sags are mainly caused due to the settlement or the displacement of the pavement surface. Sags are small, abrupt and localized. Large or long dips in the pavement can be created by the sags. 4. Edge Cracking in Flexible Pavements
