Pakistan MCQs

A total station integrates a theodolite, EDM, and onboard computing.
It speeds coordinate and topographic surveys.

An isolated footing supports one column and spreads its load.
Its size depends on column load and allowable soil pressure.

Camber sheds rainwater from the pavement surface.
Its value depends on surface type and rainfall.

A raft or mat distributes loads over a broad area.
It is useful where soil bearing capacity is low or columns are closely spaced.

Superelevation helps balance lateral acceleration on curves.
It improves comfort and reduces skidding and overturning risk.

Piles carry loads through end bearing, shaft resistance, or both.
They are used when near-surface soils are weak.

Stopping sight distance includes perception-reaction distance and braking distance.
It is a fundamental geometric-design requirement.

Bearing capacity relates to the soil's resistance to foundation loading.
Design also considers settlement, not shear failure alone.

Rigid pavements use concrete slab stiffness to distribute wheel loads.
Flexible pavements distribute load through layered materials.

Consolidation is important in saturated fine-grained soils such as clay.
Load increases pore pressure and water gradually drains out.

The subgrade is the foundation of the pavement layers.
Its strength and drainage strongly affect pavement performance.

The SPT gives an N-value related to soil density or consistency.
It also provides disturbed samples for identification.
