QUESTION: 1

Critical load position in a rigid pavement design is taken as

A.
interior loading
B.
edge loading
C.
corner loading
D.
interior, edge and corner loading

Solution:

For different combinations such as day/night, summer/winter, vehicle load, different combinations need to be considered on either of interior, edge or corner loading.

QUESTION: 2

The maximum spacing of contraction joints in rigid pavements is

A.
2.5 m
B.
3.5 m
C.
4.5 m
D.
5.5 m

Solution:

Contraction joints are spaced closer than expansion joints. As per IRC specifications, the maximum spacing of contraction joints in unreinforced CC slabs is 4.5 m and in reinforced slabs of thickness 20 cm is 14 m.

QUESTION: 3

The maximum thickness of expansion joint in rigid pavements is

A.
zero
B.
25 mm
C.
50 mm
D.
100 mm

Solution:

Expansion joints are provided to allow for expansion of the slabs due to rise in slab temperature. The approximate gap width for this type of joints is from 20 to 25 mm.

QUESTION: 4

The most suitable equipment for compacting clayey soils is a

A.
smooth wheeled roller
B.
pneumatic tyred roller
C.
sheep foot roller
D.
vibrator

Solution:

Clayey Soil Sheepsfoot Roller Vibrator Sands
Smooth Wheeled Roller Finishing of gravel and sand Pneumatic Tyred Rollers Coarse grained soils with some fines.

QUESTION: 5

The position of base course in a flexible pavement is

A.
over the sub-base
B.
below the sub-base
C.
over the sub-grade but below the sub-base
D.
over the wearing course when renewal of surface is needed

Solution:

QUESTION: 6

The modulus of sub-grade reaction is evaluated from

A.
plate bearing test
B.
CBR test
C.
direct shear test
D.
tri-axial test

Solution:

Modulus of subgrade reaction (k) is calculated from plate bearing test at 0.125 cm settlement
K = Pressure (kg/cm2) / 0.125 cm

QUESTION: 7

The load transfer to lower layers in flexible pavements is by

A.
bending action of layers
B.
shear deformation
C.
grain to grain contact
D.
consolidation of sub-grade

Solution:

Flexible pavements are those, which on the whole have low or negligible flexural strength and are flexible in their structural action under the loads. The flexible pavement layers reflects the deformation of the lower layers on-to the surface of the layer. The flexible pavement layers transmit the vertical or compressive stresses to the lower layers by grain to grain transfer through the points of contact in granular structure.

QUESTION: 8

A contraction joint is provided in concrete pavement to

A.
prevent contraction of the pavement
B.
permit cracking at the joint
C.
lower the bending moment in the pavement in order to reduce pavement thickness
D.
lower the temperature gradient across the depth of the pavement
