iii. California Resistance Value Method

iv. Triaxial Method

A cement concrete pavement is constructed at a temperature of 10⁰C. The peak summer temperature is 45⁰C. The coefficient of thermal expansion of concrete is 10 x 10^-6 per ⁰C. The gap at expansion joint is 2.5 cm. The spacing of expansion joint is:

Select the correct statements about warping stress in rigid pavements? Warping stresses are

i. caused due to seasonal variations

ii. caused due to daily variations

iii. temperature dependent

iv. a function of friction between the pavement and the layer below

Consider the following statements:

Statement 1: In rigid pavements, the flexural strength of the slab is utilized to resist the loads.

Statement 2: In rigid pavement, major criteria for failure is due to the stresses generated by wheel load action and temperature variations.

Which of the following is NOT true about longitudinal joints in rigid pavements?
