For Summer mid-day ,

S = S + Sw - Sf = 210 + 90 - 10 = 290 N/mm2

### The maximum super elevation to be provided on a road curve is 1 in 15. If the rate of change of super elevation is specified as 1 in 120 and the road width is 10m, then the minimum length of the transition curve on the either end will be

Detailed Solution for Test: Transportation Engineering- 1 - Question 3

Provide an assumption in the question  Assuming super-elevation introduction with respect to inner edge.

Since only superelevation (e = 1/15), width of road(W=10m) and rate of super-elevation (N=120) is provided. Therefore, using one of the formula to determine the length of transition curve (Ls) when super-elevation is introduced with respect to inner edge.

L_s=ⅇNW = 1/15×120×10 = 80 m

Test: Transportation Engineering- 1 - Question 4

In highway geometric design, once the cumulative speed distribution is drawn, the design adequacy is checked at

Detailed Solution for Test: Transportation Engineering- 1 - Question 4

In cumulative speed distribution following values must be designed for:
- 98th percentile speed: check for design adequacy
- 85th percentile speed: Upper speed limit
- 15th percentile speed: Lower speed limit

Test: Transportation Engineering- 1 - Question 5

Penetration to know the grade of bitumen is measured in

Detailed Solution for Test: Transportation Engineering- 1 - Question 5

Penetration value is the vertical distance traversed by the point of a standard needle into the bituminous material under specific conditions of load, time and temperature.
The distance is measured in one tenths of a millimetre.
It mean a penetration value of 80 means the actual penetration is 8mm.

Test: Transportation Engineering- 1 - Question 6

For total reaction time of 2.5 s, coefficient of friction 0.35, and design speed of 80 km/h, what is the stopping sight distance on a highway?

Detailed Solution for Test: Transportation Engineering- 1 - Question 6 Test: Transportation Engineering- 1 - Question 7

What is the superelevation for a horizontal highway curve of radius 500 m and speed 100 km/h in mixed traffic condition?

Detailed Solution for Test: Transportation Engineering- 1 - Question 7

Given data;

V = 100 Kmph

R = 500 meter

For mixed traffic conditions, Super elevation is given by formula for maximum super elevation:

e = V2/ (225 x R)

= 1002/ (225 x 500)

= 0.089 m per meter of carriage way OR

= 0.089 x 100

= 8.9 %

Test: Transportation Engineering- 1 - Question 8

A rest vertical curve joints two gradients of +3% and –2% for a design speed of 80 km/h and the corresponding stopping sight distance of 120 m. The height of driver’s eye and the object above the road surface are 1.20 m and 0.15 m, respectively. The curve length (which is less than stopping sight distance) to be provided is _________ m.

Detailed Solution for Test: Transportation Engineering- 1 - Question 11 Test: Transportation Engineering- 1 - Question 12

The design speed for a two-lane road is 80 km/h. When a design vehicle with a wheel base of 6.6 m is negotiating a horizontal curve on that road, the off-tracking is measured as 0.096 m, the required widening of carriageway of the two-lane road on the curve is approximately

Detailed Solution for Test: Transportation Engineering- 1 - Question 12 Test: Transportation Engineering- 1 - Question 13

It is proposed to widen and strengthen an existing two lane NH section as a divided highway. The existing traffic in one direction is 2500 commercial vehicles (CV) per day. The construction will take 1 yr.

The design CBR of soil subgrade is found to be 5% Given: Traffic growth rate for CV = 8% Vehicle damage factor = 3.5 (standard axles per CV) Design life = 10 yr, Traffic distribution factor = 0.75

The cumulative standard axles 9 (msa) computed are

Detailed Solution for Test: Transportation Engineering- 1 - Question 13

To compute the cumulative standard axles (msa) for the proposed highway, you need to first calculate the design traffic volume for the highway. The design traffic volume is the expected traffic volume on the highway over its design life, which in this case is 10 years. The design traffic volume can be calculated using the following formula:

Design traffic volume = (existing traffic volume + (traffic growth rate * existing traffic volume * design life)) * traffic distribution factor

Plugging in the given values, we get: Design traffic volume = (2500 + (8% * 2500 * 10)) * 0.75 = (2500 + 2000) * 0.75 = 4500 * 0.75 = 3375

Next, we need to calculate the number of standard axles that the highway will experience over its design life. The number of standard axles can be calculated using the following formula:

Number of standard axles = design traffic volume * vehicle damage factor

Plugging in the values, we get: Number of standard axles = 3375 * 3.5 = 11737.5

Finally, we can calculate the cumulative standard axles (msa) for the highway using the following formula:

Cumulative standard axles (msa) = number of standard axles * design CBR

Plugging in the values, we get: Cumulative standard axles (msa) = 11737.5 * 5% = 586.875

Rounding this value to the nearest whole number gives us 587 cumulative standard axles (msa).

Therefore, the correct answer is 1, "65."
