Types of testing in highway

• Geotechnical testing to assess soil and rock properties

• Pavement testing to evaluate the strength and durability of road surfaces

• Structural testing to ensure the safety and integrity of bridges and other structures

• Traffic flow testing to analyze traffic patterns and optimize road design

• Environmental testing to assess the impact of highways on the surrounding ecosystem

• Safety testing to evaluate...read more

There are two main types of pavement: flexible pavement and rigid pavement.

• Flexible pavement is made up of multiple layers of materials like asphalt and is designed to be flexible to distribute loads over a wider area. Example: asphalt concrete pavement.

• Rigid pavement is made up of a single layer of concrete and is designed to be stiff and strong. Example: jointed plain concrete pavement.

Core cutting is a process of extracting cylindrical samples from a structure or material for testing purposes.

• Core cutting is commonly used in construction and civil engineering to assess the quality of materials used in structures.

• The extracted core samples are typically analyzed for strength, density, composition, and other properties.

• Examples of core cutting applications include testing concrete strength in building...read more

Dense Bituminous Macadam is a type of road construction material made up of well-graded aggregates and bitumen binder.

• Consists of well-graded aggregates like crushed stone, gravel, or sand

• Bound together by bitumen binder

• Provides a strong and durable road surface

• Used in highways, airport runways, and heavy traffic areas
