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 under- laid 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?
The following 2 statements (S1 and S2) pertain to design of flexible pavements: S1: Most flexible pavement design procedures are based on Benkelman beam deflection measurements S2 : Elastic deflection is a practical non-destructive measure of pavement stiffness which relates well to fatigue failure.
