Which of the following factors is NOT needed to calculate core placement?

In the context of calculating core placement for asphalt paving, the type of asphalt used is not a direct factor in the computation. Core placement primarily concerns itself with physical dimensions and specifications that are linear and specific to the construction site.

The target yield relates to the expected volume of asphalt needed for a section, the width of the road defines how much asphalt will be required across its span, and the starting station provides a reference point from which measurements and placements can be accurately aligned.

In contrast, while the type of asphalt can influence other aspects of the paving process, such as the compaction techniques or the properties of the final surface, it does not impact the calculation of where to place the cores for testing or quality control. Therefore, understanding this distinction is key in core placement calculations.
