Geotechnical Engineer Interview Questions and Answers for Freshers

Pavement is a hard surface constructed on top of a base layer to support vehicular or foot traffic.

• Pavements are typically made of materials like asphalt, concrete, or bricks.

• They are constructed by first preparing the subgrade, then adding a base layer for support, followed by the pavement material.

• Pavements can be designed for different traffic loads and environmental conditions.

• Proper drainage is important in pavement construction to prevent water damage.

• Regular maintenanc...read more

The width of pavement varies depending on the type of road and number of lanes.

• Width of pavement can range from 10 feet for a single lane road to over 100 feet for a multi-lane highway

• Standard width for a two-lane road is typically around 24 feet

• Interstate highways can have pavement widths of up to 48 feet per lane
