A project is expected to take 15 months along the critical path, having a standard deviation of 3 months.The probability of completing the project within 12 months is
A)
15.87%
B)
17.85%
C)
50.00%
D)
84.13%
Every path is a trail because a path does not repeat vertices and therefore cannot repeat edges.

Bitumen is derived from
A)
destructive distillation of coal tar
B)
destructive distillation of petroleum
C)
fractional distillation of petroleum
D)
naturally occurring ores
AGE can be calculated from DATE_OF_BIRTH, so it is a derived attribute.

The effective stress friction angle of a saturated, cohesionless soil is 38°. The ratio of shear stress to normal effective stress on the failure plane is
A)
0.781
B)
0.616
C)
0.488
D)
0.438
In a direct shear box test, failure is forced along the predefined horizontal plane.

The initial concavity in the load-penetration curve of a CBR test is NOT due to
A)
uneven top surface
B)
high impact at start of loading
C)
inclined penetration plunger
D)
soft top layer of soaked soil
CBR is load at standard penetration divided by the standard load, giving 5% for the supplied 50 kg value.

Terzaghi and Peck’s settlement chart is based on the fact that N-value represents
A)
Density
B)
Moisture content
C)
Relative density
D)
Surcharge
Unused TTL inputs should not float; they are tied to the appropriate logic level.

The net ultimate bearing capacity of a purely cohesive soil
A)
Depends on width of footing and is independent of depth of footing
B)
Depends on width of footing and is independent of width of footing
C)
Depends on both depth and width of footing
D)
Is independent of both depth and width of footing
Correct option: A — Depends on width of footing and is independent of depth of footing. This matches the standard definition/result for the stated question.

As per IRC:37-2012, in order to control subgrade rutting in flexible pavements, the parameter to be considered is
A)
horizontal tensile strain at the bottom of bituminous layer
B)
vertical compressive strain on top of subgrade
C)
vertical compressive stress on top of granular layer
D)
vertical deflection at the surface of the pavement
Flexible pavement rutting is controlled by limiting vertical compressive strain on top of the subgrade.
