Roads and Buildings Department Interview Questions and Answers

Moment of inertia measures an object's resistance to rotational motion, crucial for beam stability in engineering.

• Moment of inertia (I) is calculated as I = ∫ r² dm, where r is the distance from the axis of rotation.

• Higher moment of inertia indicates greater resistance to bending and deflection in beams.

• For example, an I-beam has a higher moment of inertia compared to a rectangular beam of the same material and height.

Soil stabilization techniques enhance soil properties for construction, improving strength, durability, and load-bearing capacity.

• Mechanical Stabilization: Involves compaction and mixing soil with aggregates. Example: Gravel roads.

• Chemical Stabilization: Uses additives like lime or cement to improve soil properties. Example: Lime stabilization for clay soils.

• Bituminous Stabilization: Incorporates bitumen to enhance moi...read more

Standard tests on concrete ensure its strength, durability, and overall quality for construction projects.

• Compressive Strength Test: Measures the concrete's ability to withstand axial loads, typically using a cube or cylinder sample.

• Slump Test: Assesses the workability and consistency of fresh concrete by measuring the slump of a cone.

• Flexural Strength Test: Evaluates the tensile strength of concrete by applying a load...read more
