Duties of quality control in road construction?

1. Inspecting materials: Quality control personnel are responsible for inspecting all materials used in road construction, including aggregates, asphalt, concrete, and other materials to ensure they meet project specifications and standards.

2. Testing materials: Quality control personnel conduct various tests on materials to ensure they meet required standards, such as density tests, gradation tests, and moisture content tests.

3. Monitoring construction processes: Quality control personnel monitor construction processes to ensure that proper procedures are followed and that work is being done according to project specifications.

4. Conducting quality checks: Quality control personnel conduct regular quality checks throughout the construction process to identify any defects or issues that may affect the quality of the road.

5. Documenting and reporting: Quality control personnel document all quality control activities, including test results, inspections, and any issues or concerns that arise during construction. They also report findings to project managers and other stakeholders.

6. Implementing corrective actions: If any issues or defects are identified during quality control inspections, personnel are responsible for implementing corrective actions to address the problem and ensure that the road meets required standards.
