-
In cement concrete pavements, tie bars are provided across:
सही उत्तर: क) Longitudinal joints, to hold adjacent slabs together
Tie bars are deformed bars across longitudinal joints that prevent the lanes from separating; dowel bars at transverse joints transfer load.

Alligator (crocodile) cracking in a flexible pavement mainly indicates:
सही उत्तर: ख) Fatigue failure under repeated wheel loads, often due to a weak base or subgrade
Interconnected cracks forming a pattern like crocodile skin result from fatigue of the bituminous layer, often with inadequate support below.

In standard road signage practice followed in Nepal and South Asia, mandatory (regulatory) signs such as 'No entry' or speed limits are generally:
सही उत्तर: ग) Circular
Regulatory signs are circular, warning signs are triangular and informatory signs are rectangular; 'Stop' is the octagonal exception.

The Benkelman beam is used in highway engineering to measure the:
सही उत्तर: ग) Rebound deflection of a flexible pavement under a standard axle load
The Benkelman beam measures surface deflection under a loaded truck; the rebound deflection is used to evaluate and design overlays.

-
Vertical curves joining two gradients on highway longitudinal profiles are usually designed as:
सही उत्तर: घ) Parabolas
A simple parabola gives a constant rate of change of grade and is easy to set out, so it is used for summit and valley curves.

-
The long chord of a simple circular curve of radius R and deflection angle Δ is:
सही उत्तर: क) 2R sin(Δ/2)
The long chord subtends Δ at the centre, so its length is 2R sin(Δ/2); R(1 − cos(Δ/2)) is the mid-ordinate.

For stereoscopic coverage in aerial photogrammetry, the forward (longitudinal) overlap between successive photographs is normally about:
सही उत्तर: ख) 60%
A forward overlap of about 60% and side overlap of about 25-30% are normally specified so that every point appears in at least two photographs.

-
The slope correction for a length L measured along a uniform slope, where h is the difference in height between its ends, is approximately:
सही उत्तर: ख) h²/(2L), subtractive
Horizontal length = √(L² − h²) ≈ L − h²/(2L), so the correction h²/(2L) is subtracted.

-
The correction for sag of a tape of length L and weight w per unit length, suspended between two supports under a pull P, is:
सही उत्तर: ग) w²L³/(24P²), always subtractive
A sagging tape records a length greater than the chord, so the sag correction Cs = w²L³/(24P²) is always negative.

-
The 'two-peg test' on a dumpy level is carried out to check whether:
सही उत्तर: घ) The line of collimation is parallel to the axis of the bubble tube
Readings on two pegs from a midpoint and from near one peg reveal any collimation error, i.e. the line of sight not being horizontal when the bubble is central.
