For core placement, what does the term "offset" refer to?

In the context of core placement, the term "offset" specifically refers to the distance from the edge of the pavement. This measurement is crucial in ensuring that the core samples taken for testing are representative of the overall pavement structure, as they must be positioned correctly relative to the edge. This way, the samples can accurately reflect the quality and characteristics of the asphalt in the area being analyzed. By maintaining a consistent offset, technicians can ensure that they are measuring the intended section of the pavement, thereby acquiring reliable data for evaluation and assessment of the asphalt's performance and integrity.
