[IES 2007]

Codes: A B C D

  1.  4  2  1  3
  2.  4  2  3  1
  3.  2  4  3  1
  4.  2  4  1  3
Answer: Option B
Explanation:
  • Check walls are small retaining structures provided in series to arrest landslides and to add stability to hill face.
  • Breast walls are the walls built to prevent the soil on a natural slope embankment from sliding down the slope due to harsh weather effects like landslides, erosion etc.,
  • Gabion walls are provided for retaining fill portion, and constructed with dry stone masonry encased in wire mesh or geo-grid cages.

13.  Consider the following statements with reference to Water Bound Macadam (WBM) and Wet Mix Macadam (WMM):

  1. WBM is a road mix and WMM is a plant mx. 
  2. WBM usually has plastic filler, while WMM has non-plastic filler
  3. WBM is a modern road mix and WMM is a traditional road mix

Which of these statements is/are correct ?

[IES 2008]

  1. 2 and 3
  2. 1 only
  3. 2 only
  4. 1 and 2
Answer: Option D
Explanation:
WBM is a traditional road mix and WMM is a modern road mix.

14.  Hot bitumen is sprayed over freshly constructed bituminous surface followed by spreading of 6.3 mm coarse aggregates and rolled. Which one of the following is indicated by this type of construction ?

[IES 2009]

  1. Gravel-bitumen mix
  2. Liquid seal coat
  3. Seal coat
  4. Surface dressing
Answer: Option D
Explanation:
Surface dressing is the process of application of hot bituminous material followed by spreading of aggregate cover and rolling.

15.  Assertion (A): In water-bound macadam construction, grade I has better load dispersion characteristics as compared to grade III aggregates.

Reason (R): The plasticity index of the binding material should be less than 6%.

[IES 2009]

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not a correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer: Option D
Explanation:
Aggregates are divided into 3 grades based on their size.
  • Grade 1 - particles of size between 90 mm and 40 mm
  • Grade 2 - particles of size between 63 mm and 40 mm
  • Grade 3 - particles of size between 50 mm and 20 mm
The load dispersion of aggregates is as follows:
Grade 3 > Grade 2 > Grade 1

16.  A road passes through a cut with impervious strata at a depth of 1.25 m from the sub-grade level. To intercept seepage flow, a longitudinal pipe drain in a trench filled with filter material and clay seal is constructed. What will be the required depth of the trench ? 

[IES 2013]

  1. 2.5 m
  2. 1.5 m
  3. 1.25 m
  4. 0.5 m
Answer: Option C
Explanation:
The depth of the trench should be equal to the depth of impervious strata below the subgrade level.

17.  Flexible concrete is a mix comprising of _____ .

[IES 2016]

  1. Sand, filler and 30/40 bitumen only
  2. Gravel, sand, filler and 60/70 bitumen 
  3. Sand, filler and 60/70 bitumen only
  4. Gravel, filler and 30/40 bitumen
Answer: Option B
Explanation:
Flexible concrete is a mix consisting of gravel, sand, filler and bitumen.

18.  Statement (I): PC is a preferred raw material for construction of Bituminous pavements in areas of heavy rainfall.

Statement (II): In PCA, no stripping is needed as there is improved binding;and thereby stability is also improved.

[IES 2018]

  1. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I).
  2. Both Statement (I) and Statement (II) are individually true but Statement (II) is not a correct explanation of Statement (I).
  3. Statement (I) is true but Statement (II) is false.
  4. Statement (I) is false but Statement (II) is true.
Answer: Option A
Explanation:

19.  Which of the following are the design elements in highway embankments ?

  1. 2 and 3 only
  2. 1 and 3 only
  3. 1 and 2 only
