What are the functions of surface in flexible pavement What

Solution

1. surface provides characteristics such as friction, smoothness, drainage, etc. Also it will prevent the entrance of excessive quantities of surface water into the underlying base, sub-base and sub-grade

2.It provides toughness to resist the distortion under traffic and provide a smooth and skid- resistant riding surface,

3. It provides water proof resistance to protect the entire base and sub-grade from the weakening effect of wate
