Question

i) What is the cause of frequent cracks on our roads?
ii) How do the tonga-drivers vary according to the towns they belong to?​

Answer 1

Answer:

answer 1 -Fatigue cracking occurs through failure of the pavement surface under repeated traffic loading and localized tensile stress from heavy loads. These tensile stresses are caused by inadequate support, such as stripping in the bottom portion of the asphalt layer, or loss of subgrade or base support, as from poor drainage.
