ⓐ O.M.C ⓑ Dry density ⓒ M.D.D ⓓ Saturated density
➤ M.D.D
The maximum density which is desirable in highway embankments is M.D.D, if it is greater than MDD then it’s density decreases.
17➤ Which of the following is the last step in chain surveying?
After having completed the preliminary work, the chaining may be started from the base line. The work in running a survey line is twofold, to chain the line and to locate the adjacent details.
18➤ In which of the following areas does compass surveying is not recommended?
ⓐ Large areas ⓑ Crowded with many details ⓒ Undulating areas ⓓ Local attraction suspected areas
➤ Local attraction suspected areas
Compass surveying is not recommended for areas where the local attraction is suspected due to the presence of a magnetic substance.
19➤ Which of the following classification in surveying is based on the instrument used?
Topographic surveying, Hydrographic surveying, Cadastral surveying classification is based on the nature of field survey.
Traverse surveying, chain surveying is classified based on the type of instrument used.
20➤ Which of the following type of surveying is used for exploring mineral wealth?
For exploring mineral wealth mine surveying is used. Determining points of strategic importance is military surveying.
21➤ Which of the following cannot be done with the help of theodolite in surveying?
ⓐ Locating points on lines ⓑ Laying off horizontal angles ⓒ Measuring horizontal distances ⓓ Prolonging survey lines
➤ Measuring horizontal distances
Theodolite is the most precise instrument designed for the measurement of horizontal and vertical angles. It has wide applicability in surveying such as laying off horizontal angles, locating points on line, prolonging survey lines, establishing grades etc.
22➤ Which of the following is an indirect method of surveying?
ⓐ Chain surveying ⓑ Tacheometry ⓒ Countouring ⓓ All of the mentioned
➤ Tacheometry
Generally, horizontal distances are measured by direct methods, i.e. laying of chains or tapes on the ground. These methods are not always convenient if the ground is undulating, rough, difficult and inaccessible. Under these circumstances, indirect methods are used to obtain distances. One such method is “Tacheometry”.
