Test: Transportation Engineering- 2 - Question 1

For carrying out bituminous patch work during the rainy season, the most suitable binder is

Detailed Solution for Test: Transportation Engineering- 2 - Question 1

Emulsion is generally used for cold and wet climate condition. For bituminous patch work during rainy season bituminous emulsion is used.

Test: Transportation Engineering- 2 - Question 2

Bituminous materials are commonly used in highway construction because of their good

Detailed Solution for Test: Transportation Engineering- 2 - Question 2

Bitumen is derived from fraction distillation of petroleum and is commonly used because of binding and water-proofing properties. These properties prevent water going down to subgrade and thus, leading to better strength of the flexible pavement.

Test: Transportation Engineering- 2 - Question 3

In cement concrete pavements, tie bars are installed in

Test: Transportation Engineering- 2 - Question 4

The following general statement may be made about the penetration value and softening point of bitumen

Detailed Solution for Test: Transportation Engineering- 2 - Question 4

Penetration Test- Represents hardness/softness of bitumen by measuring the depth of penetration 1/10 of mm to which a standard needle carrying a weight of 100 gram penetrates in 5 seconds.
Softening point Test- The temperature at which a standard ball passes through the sample of bitumen and falls when heated under water or glycerine. It represents the fluidity of binder.
Higher the penetration value means the needle will go into larger depth while performing penetration test. Thus, high penetration generally means the consistency of bitumen is soft and thus, can be turned into liquid even at low temperatures. This results in lower softening point.

Test: Transportation Engineering- 2 - Question 5

The minimum length of the overtaking zone should be

Test: Transportation Engineering- 2 - Question 6

In case of the valley curves or sag curves the maximum possible deviation angle is obtained when

Detailed Solution for Test: Transportation Engineering- 2 - Question 6

Test: Transportation Engineering- 2 - Question 7

The bitumen with viscosity reduced by volatile diluents is known as

Detailed Solution for Test: Transportation Engineering- 2 - Question 7

Bitumen Emulsion- Bitumen is dispersed in fine globules in water.
Cutback Emulsion- Volatile dilutants makes the bitumen easy to be laid. Once laid easily the dilutant evaporates due to its volatile nature. 
Asphalt- Also known as Bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum.

Test: Transportation Engineering- 2 - Question 17

Consider the following parameters related to a rotary intersection:

1. Width of the weaving section
2. Length of the weaving section
3. Proportion of weaving traffic
4. Weaving angle
5. Width of the carriageway at entry

Capacity is generally expressed in terms of 

Detailed Solution for Test: Transportation Engineering- 2 - Question 17

The practical capacity (Qp) of the rotary is dependent on the minimum capacity of the individual weaving section. where w is width of weaving section e is average of entry e1 and width of nonweaving section e2 for the range e/W = 0.4 to 1.0 L is the length of the weaving section P is proportion of weaving traffic
