Roman roads had zero gradient. The main functional reason for this was —
Reduce construction cost
Ensure rapid military movement
Improve drainage on flat terrain
Minimize erosion of broken stone layers
Tresaguet method uses a side drain with slope 1 in 20. The main engineering advantage of this compared to Roman roads is —
Improved lateral stability
Reduced construction thickness
Better removal of surface water
Cheaper stone requirement
Nagpur plan density = 16 km / 100 km². If a district covers area = 5000 km², the minimum recommended road length is —
400 km
600 km
800 km
1000 km
A highway widening project executed under DBFO model mainly shifts which risk to the concessionaire?
Technical risk
Financial & revenue risk
Land acquisition risk
Traffic control risk
As per Indian classification, an Expressway differs functionally from National Highway because—
It permits heavy vehicles only
It has controlled access with grade-separated junctions
It is constructed only by NHAI
It has maximum speed of 80 km/h
TRUE/FALSE
Metcalf construction introduced the concept of varying stone size from center to edge (a)
TRUE/FALSE
Village Roads (VR) are tertiary system roads as per the 3rd Road Plan (a)
Correctly match the following:
NH →
national importance
SH →
district HQ, major towns
MDR →
rural routes
VR →
lowest category (<600 veh/day)
Q8. (Road Patterns – Reasoning)
Assertion (A): Radial & grid pattern improves overall travel efficiency inside urban areas.
Reason (R): Grid network ensures redundancy while radial network shortens the average path to the city center.
A) A & R true; R explains A
B) A & R true; R does not explain A
C) A true; R false
D) Both false
The father of modern road construction is (a)
The Golden Quadrilateral connects four metropolitan cities using National Highways such as NH 2, NH 4, NH 5, and (a) .
As per IRC, recommended speed for State Highways (SH) is up to (a) km/h.
In water bound macadam roads, screenings fill the (a) between coarse aggregates.
Expressways are designed for a minimum speed of (a) km/h as per classification.
MATCH THE FOLLOWING
A. Roman road
4. Thick layered stone foundation
B. Tresaguet method
3. Side drainage, 300 mm depth
C. Telford method
1. Screening fills voids
D. Macadam method
2. Slope 1 in 36 all layers
