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. 
Which of the above statements are correct?
