Highway Civil Engineer Interview Questions and Answers

IRC recommends 8-10 passes of vibro roller for full compaction.

• IRC (Indian Road Congress) recommends 8-10 passes of vibro roller for full compaction.

• The number of passes may vary depending on factors such as soil type, moisture content, and thickness of the layer.

• In some cases, additional passes may be required to achieve the desired level of compaction.

• It is important to conduct regular tests to ensure that the desired level of compaction has been achieved.

• Proper compaction ...read more

The quantity of soil in embankment or subgrade can be determined using the method of average end area.

• The method of average end area involves taking cross-sectional measurements at regular intervals along the embankment or subgrade.

• The cross-sectional measurements are used to calculate the area of each section.

• The average area is then multiplied by the length of the embankment or subgrade to determine the volume of soil.

• The formula for calculating the volume is: Volume = Aver...read more

The standard MDD (Maximum Dry Density) of subgrade soil varies depending on the specific project requirements and soil characteristics.

• The standard MDD of subgrade soil is determined through laboratory tests.

• It is influenced by factors such as soil type, compaction method, moisture content, and compaction effort.

• Different soil types have different standard MDD values.

• For example, the standard MDD of a sandy soil may be different from that of a clayey soil.

• The standard MDD is ...read more

Earthwork refers to the process of moving, excavating, and compacting soil and rock to prepare the ground for construction.

• Earthwork involves activities such as excavation, grading, compaction, and backfilling.

• It is essential for creating a stable foundation for roads, buildings, and other structures.

• Earthwork also includes the removal of unwanted materials and the addition of necessary materials to achieve the desired elevation and slope.

• Examples of earthwork include digging...read more

GSB stands for Granular Sub Base and WMM stands for Wet Mix Macadam. GSB WMM is a type of road construction method using layers of granular materials.

• GSB is the layer of granular material placed on the subgrade of a road to provide a stable foundation.

• WMM is a mixture of aggregates, filler, and water laid on the GSB layer to form a strong base for the road.

• GSB WMM construction involves compacting each layer properly to ensure durability and strength of the road.

• Example: GSB l...read more
