Structural Site Engineer Interview Questions and Answers

The recommended thickness for Dry Lean Concrete (DLC) is typically between 100mm to 150mm, depending on the application.

• Standard Thickness: Generally, DLC is recommended to be 100mm to 150mm thick for most applications.

• Sub-base Layer: In road construction, DLC serves as a sub-base layer, providing a stable foundation for asphalt or concrete pavements.

• Load Distribution: A thickness of 150mm may be used in areas with heavier loads to ensure adequate load distribution and preven...read more

The most cost-effective pavement maintenance method is preventive maintenance, which extends pavement life and reduces long-term costs.

• Preventive maintenance includes sealcoating and crack sealing, which protect the pavement from moisture and deterioration.

• Regular inspections help identify issues early, allowing for timely repairs that are less costly than major overhauls.

• Using materials like asphalt overlays can rejuvenate existing pavements at a fraction of the cost of comp...read more

The impact value of road tyres measures their resistance to impact forces, crucial for safety and performance in vehicles.

• Impact Value Testing: This involves dropping a weight onto a tyre sample to assess its durability and resistance to sudden forces.

• Safety Implications: Higher impact values indicate better performance in absorbing shocks, reducing the risk of blowouts during driving.

• Material Composition: Tyres made from high-quality rubber and reinforced with materials like...read more
