Practice Set-1: Highway Alignment

---

1. An index map used in a highway project primarily shows:

a) Proposed and existing roads with important places b) Details of various alternate alignments c) General topography of the area d) Existing structures like buildings and wells

Correct Answer: a) Proposed and existing roads with important places

An index map provides an overview of the project area showing existing and proposed roads along with important landmarks.

2. The correct sequence of engineering surveys for highway alignment is:

a) Map study → Reconnaissance → Preliminary survey → Detailed survey → Final location survey b) Reconnaissance → Map study → Preliminary survey → Final location survey → Detailed survey c) Map study → Reconnaissance → Preliminary survey → Final location survey → Detailed survey d) Reconnaissance → Preliminary survey → Map study → Detailed survey → Final location survey

Correct Answer: a) Map study → Reconnaissance → Preliminary survey → Detailed survey → Final location survey

This is the standard sequence of surveys for highway alignment, starting with broad planning and progressively becoming more detailed.

---

3. The survey in which the final alignment is selected is:

a) Reconnaissance survey b) Preliminary survey c) Detailed survey d) Final location survey

Correct Answer: b) Preliminary survey

The preliminary survey is where detailed measurements are taken and the final alignment is selected from alternative routes.

---

4. Which of the following is NOT a factor in highway alignment selection?

a) Obligatory points b) Traffic volume c) Political boundaries d) Availability of construction materials

Correct Answer: c) Political boundaries

While political boundaries might influence administrative decisions, they are not a technical factor in alignment selection unlike the other options.

---

5. The purpose of a reconnaissance survey is to:

a) Finalize the alignment b) Study alternative routes roughly c) Conduct soil testing d) Prepare detailed drawings

Correct Answer: b) Study alternative routes roughly

The reconnaissance survey is a preliminary field investigation to identify possible alternative routes for further study.

---

6. Which survey helps in identifying obligatory points?

a) Traffic survey b) Reconnaissance survey c) Preliminary survey d) Detailed survey

Correct Answer: b) Reconnaissance survey

Obligatory points (locations the highway must pass through) are identified during the reconnaissance phase of the survey.

---

7. The best alignment for a highway is selected in which stage?

a) Map study b) Reconnaissance c) Preliminary survey d) Final location survey

Correct Answer: c) Preliminary survey

The preliminary survey involves detailed measurements and analysis to select the best alignment from alternatives.

---

8. Which of the following is NOT a type of highway survey?

a) Traffic survey b) Geological survey c) Market survey d) Preliminary survey

Correct Answer: c) Market survey

Market surveys are not part of highway engineering surveys, while the other options are all relevant survey types.

---

9. The main objective of a detailed survey is to:

a) Estimate project cost b) Finalize geometric design c) Identify obligatory points d) Study alternative routes

Correct Answer: b) Finalize geometric design

The detailed survey provides precise data needed to finalize the highway's geometric design including alignment, cross-sections, etc.

---

10. Which survey provides data for preparing longitudinal and cross-sections?

a) Reconnaissance survey b) Preliminary survey c) Detailed survey d) Traffic survey

Correct Answer: c) Detailed survey

The detailed survey collects precise elevation data along the alignment needed to prepare longitudinal profiles and cross-sections.
