Question

Discuss about maintenance of highways along with failure of flexible and rigid pavement

Answer 1

hey

Explanation:

Alligator Cracking of Flexible Pavements Alligator cracks are also called as map cracking

.This is a fatigue failure caused in the asphalt concrete. A series of interconnected cracks are observed due to such distress.

The tensile stress is maximum at the asphalt surface (base).

Answer 2

$\huge\bold\green {HOLA!!}$

In general, the flexible pavement consists of the following component layers:

Sub-grade

Sub-base course

Base Course

Surface Course

Instability in any of the layers will result in the complete failure of the pavement system. This makes it necessary to construct each layer with utmost care and precision.
