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. In a flexible pavement, any deformation in the top layers is transferred to underlaid layers; but, in rigid pavements, there is slab or beam action due to which any deformation is only in the top layer of the concrete slab.
