A) Gradient
B) Cant
C) Banking
D) Super-elevation
Option (A)
Explanation :
Gradient : Rate of rise or fall along the length of road.
Super-elevation : Rising of outer edge of pavement with respect to inner on a horizontal curve.

Nil.
Q.11) An engineering survey is proposed for a highway alignment project. The survey includes following stages :
- Preliminary Survey
- Reconnaissance
- Map study
- Final location & detailed survey.
A) 2-1-3-4
B) 1-3-2-4
C) 2-3-1-4
D) 3-2-1-4
Option (D)
Explanation :
The correct suquence of survey involves :
Map study > Reconnaissance > Preliminary > FInal location & Detailed survey.
Q.13) Enoscope is used to find –
A) spot speed and space mean speed
B) space mean speed only
C) spot speed only
D) flow of vehicles only
Option (C)
Explanation :
The Enoscope functions as a toolbox to calculate a vehicle’s spot speed, also called the “Mirror Box Method.” This approach is the simplest and most cost-effective for determining spot speed, though it has the drawback of being slow. It involves placing a mirror box at the road’s edge to observe and reflect a vehicle’s image across the road at a 90° angle.
Q.14) The minimum green time required for vehicular traffic on any of the approaches is –
A) 20 sec
B) 16 sec
C) 25 sec
D) 30 sec
Option (B)
Explanation :
Nil.
Q.15) Lime stone dust filler material is required for the production of –
A) Surface Dressing
B) Built-up-spray grout
C) Wet-mix-macadam
D) Mastic Asphalt
Option (D)
Explanation :
Nil.
Q.16) VG 30 grade of bitumen is suitable for 7-days average maximum air temperature of –
A) >45
B) 30-38
C) 38-48
D) <30
Option (B)
Explanation :
VG stands for Viscosity Grade.
The ranges of Viscosity for different grades @ 600 C –
VG 10 = 800 to 1200
VG 20 =1600 to 2400
VG 30 = 2400 to 3600
VG 40 = 3200 to 4000
The various applications are –
VG 10 – Suitable for road construction in chilly environments. Excellent for application through spraying. Utilized in the manufacturing of bitumen emulsion.
VG 20 – Used in cold regions for road construction.
VG 30 – Enhances asphalt performance in high-temperature zones.
VG 40 – Effective in regions experiencing heavy traffic demands. Particularly suitable for road construction during hot weather conditions.
Q.17) Softening point of a straight run-bitumen is determined by –
A) Strength and Toughness
B) Spectrometer
C) Ring and Ball Method
D) Durability
Option (C)
Explanation :
Nil.
Q.18) Which type of stresses develop in cement concrete pavement due to temperature?
A) Warping stress and Frictional stress
B) Warping stresses
C) Frictional stresses
D) No stress
Option (A)
Explanation :
Warping stresses are developed due to daily variation in temperature whereas Frictional stresses are developed due to seasonal variations.
Q.19) What is the purpose of Tie bars in Rigid pavements?
A) Resisting changes due to temperature
B) Preventing trailing cracks
C) Load transfer
D) To firmly tie longitudinally adjacent slabs
Option (D)
Explanation :
