BEIGH CONSTRUCTION COMPANY PvT. Civil Engineer-Highway/Roadway Interview Questions and Answers

Q1. What will happened when use soil compactor on GSB & wmm layer which deadload 12 ton or above?
Ans. 
Using a soil compactor on GSB & WMM layers with a deadload of 12 tons or above can lead to excessive compaction and potential damage to the layers.
• Excessive compaction can result in reduced permeability of the layers, affecting drainage.

• The excessive force from the compactor can cause cracking or deformation in the layers.

• It may also lead to uneven settlement and structural instability in the pavement.

• Proper evaluation...read more

Q2. Why does use SMA layer in High speed express way?
Ans. 
SMA layer is used in high speed expressways for its superior durability, rut resistance, and fatigue resistance.
• SMA (Stone Matrix Asphalt) layer provides superior durability compared to traditional asphalt mixes.

• SMA layer has excellent rut resistance, maintaining a smooth surface for high speed traffic.

• The high binder content in SMA enhances fatigue resistance, reducing cracking and extending pavement life.

• SMA mixtures...read more

Q1. Tell me about PQC , DLC , GSB
Ans. 
PQC, DLC, and GSB are all types of road construction materials.
• PQC stands for Pavement Quality Concrete and is a type of concrete used for road surfaces.

• DLC stands for Dry Lean Concrete and is a type of concrete used as a base layer for road construction.

• GSB stands for Granular Sub Base and is a layer of compacted granular material used as a foundation for road construction.

• All three materials are commonly used in road...read more

Q2. Tell Me about GSB Gradation
Ans. 
GSB Gradation is a method of grading aggregates used in road construction.
• GSB stands for Granular Sub-Base.

• It is a method of grading aggregates based on their particle size.

• The gradation is important for ensuring proper compaction and stability of the road.

• The gradation is specified in terms of percentage passing different sieve sizes.

• For example, GSB 20 gradation means that 100% of the aggregates pass through a 20mm s

Q3. Rigid and Flexible Pavement difference
Ans. 
Rigid pavements are made of concrete while flexible pavements are made of asphalt.
• Rigid pavements have high flexural strength and low deflection while flexible pavements have low flexural strength and high deflection.

• Rigid pavements are more durable and have a longer lifespan than flexible pavements.

• Flexible pavements are easier and cheaper to construct and maintain than rigid pavements.

• Examples of rigid pavements incl...read more
