10 Questions

Flexible pavements depend on aggregate interlock, particle friction, and cohesion for stability:

True

In flexible pavement, the highest-quality materials are located in the subgrade:

False

The principal elements of flexible pavement structure are wearing surface, base, subbase, and subgrade:

True

The base layer of flexible pavement is primarily responsible for spreading the stresses created by wheel loads acting on the wearing surface:

True

Subbase layer in flexible pavement is always made of granular material and is used in areas with severe frost action or extremely weak subgrade soil:

False

Flexible pavements are primarily designed to distribute loads to the surface rather than the subgrade.

False

The wearing surface in flexible pavements must be capable of withstanding wear and abrasive effects of moving vehicles.

True

The base layer in flexible pavements is primarily responsible for spreading the stresses created by wheel loads acting on the wearing surface.

False

In some cases, the subgrade in flexible pavements will simply be the natural earth surface.

True

Subbase layer in flexible pavements is always made of granular material and is used in areas with severe frost action or extremely weak subgrade soil.

False
