How often should straight edge calibrations be checked during a project?

Regular calibration of the straight edge is vital to ensure proper quality control in asphalt paving projects. Checking the calibration at the start of each working period ensures that the equipment is ready for accurate measurements. This timing allows any potential issues to be identified and rectified before work begins, promoting consistency in the leveling and smoothness of the asphalt surface.

While multiple checks throughout the day may seem prudent, they can be resource-intensive and unnecessary if proper initial calibration is performed. Similarly, only checking when problems are detected can lead to significant complications, as issues may go unnoticed until they cause larger problems later in the project. Therefore, calibrating at the beginning of each working session strikes a balanced approach to maintaining quality while ensuring that resources are allocated efficiently.
