Question 1

The data given below pertain to the design of a flexible pavement are
Initial traffic = 1213 cvpd
Traffic growth rate = 8 percent per annum
Design life = 12 years
Vehicle damage factor = 2.5
Distribution factor = 1.0
The design traffic in terms of million standard axles (msa) to be catered would be

Question 2

Maximum strains in an extreme fibre in concrete and in the tension reinforcement (Fe–415 grad and Es = 200 kN/mm²) in a balanced section at limit state of flexure are respectively

Question 3

Group–I contains some properties of concrete/cement and Group–II contains list of some tests on concrete/cement. Match the property with the corresponding test.
Group I
P workability of concrete
Q tensile strength of concrete
R bond between concrete and steel
S fineness of cement
Group II
1. cylinder splitting test
2. Vee–Bee test
3. surface area test
4. fineness modulus test
5. pull out test

Correct codes pair is:

Question 4

A Marshall specimen is prepared for bituminous concrete with a a bitumen content of 5 percent by weight of total mix. The theoretical and the measured unit weights of the mix are 2.442 g/cm³ and 2.345 g/cm³, respectively. The bitumen has a specific gravity of 1.02. The percent voids in mineral aggregate filled with bitumen (VFB) are

Question 5

In the context of flexible pavement design, the ratio of contact pressure to tyre pressure is called the Rigidity Factor. This factor is less than unity when they tyre pressure is

Question 6

Select the strength parameter of concrete used in design of plain jointed cement concrete pavements from the following choices:

Question 7

On an urban road, the free mean speed was measured as 70 kmph and the average spacing between the vehicles under jam condition as 7.0 m. The speed-flow -density equation is given by
$Description: D:\GradeStack Courses\GATE Tests (Sent by Ravi)\Civil Engg\Civil Engineeing-01-Apr\Civil-Engineering-2006-01-Apr-1_files\image264.png$
where U = space-mean speed (kmph); U_sf = free mean speed (kmph); k = density (veh/km); k_j = jam density (veh/km); q = flow (veh/hr). The maximum flow (veh/hr) per lane for this condition is equal to

Question 8

Road roughness is measured using

Question 9

The minimum value of 15 minute peak hour factor on a section of a road is

Question 10

The road geometrics in India are designed for the
