What condition of the flexible pavement would require a complete reconstruction of the pavement? Correct Answer Improper compaction of lower layers

The failure due to improper compaction of the lower layers requires a complete reconstruction of the flexible pavement. The instability of the underlying layer caused due to excessive moisture content requires designing a proper subsurface drainage system. A highly plastic subgrade requires treatment of the subgrade soil by stabilization.

Consider the following statements regarding pavements: 1. Rigid pavements are more suitable than flexible pavements for stage construction. 2. Rigid pavements are more affected by temperature variations than flexible pavements. 3.
