Shree Swami Samarth Engineering Highway Engineer Interview Questions, Process, and Tips

Minimum thickness of PCC for crush barrier is typically 150mm to 200mm.

• Minimum thickness of PCC for crush barrier is usually 150mm to 200mm.

• The thickness may vary depending on the design requirements and load capacity.

• It is important to consult relevant codes and standards for specific guidelines.

• For example, British Standards recommend a minimum thickness of 150mm for PCC crush barriers.

Minimum thickness of DBM is typically around 50-75 mm.

• Minimum thickness of DBM (Dense Bituminous Macadam) is usually around 50-75 mm.

• The thickness may vary depending on the specific project requirements and traffic loads.

• DBM is commonly used as a base or binder course in road construction.

• Proper compaction is essential to achieve the desired strength and durability of DBM layers.

Minimum thickness of dlc is typically around 1-2 microns.

• Minimum thickness of DLC (Diamond-Like Carbon) coatings is usually around 1-2 microns.

• Thicker DLC coatings (e.g. 5-10 microns) may be used for applications requiring higher wear resistance.

• The specific minimum thickness may vary depending on the application and requirements.

Minimum height of retaining wall depends on factors like soil type, slope angle, and load bearing capacity.

• Minimum height of retaining wall should be at least 0.6 times the total height of the wall above the ground level.

• Factors such as soil type, slope angle, and load bearing capacity should be considered when determining the minimum height.

• For example, a retaining wall in sandy soil with a steep slope may require a t...read more

The maximum height of a retaining wall is determined by factors such as soil type, slope angle, and load bearing capacity.

• The maximum height of a retaining wall is typically limited by the stability of the soil behind it.

• Factors such as the type of soil, slope angle, and the load the wall will bear all play a role in determining the maximum height.

• For example, a retaining wall made of reinforced concrete can typically ...read more
