If a core does not delaminate, what should the technician do next?

When a core does not delaminate, indicating that it is properly bonded to the underlying layers of asphalt, the technician should continue drilling until the sample is secured. This approach ensures that the integrity of the core is maintained and that it can be extracted without compromising the quality of the sample. Continuing the drilling process allows the technician to carefully and effectively obtain the necessary material for analysis while minimizing disturbance to the surrounding area.

Maintaining a proper technique during the extraction process is crucial for obtaining quality samples that are representative of the asphalt pavement structure. By focusing on securing the sample through continued drilling, the technician ensures that the core can be accurately evaluated during testing.
