What is the purpose of marking 50 feet from each side of the deficiency on a rolling straight edge?

Marking 50 feet from each side of the deficiency on a rolling straight edge serves the important purpose of outlining the section requiring repairs. This practice is crucial in identifying the specific area on the pavement where deficiencies exist, allowing for effective intervention.

When a deficiency, such as a dip or high spot, is detected during the use of a rolling straight edge, the marked area provides a clear, defined zone for evaluating the extent of the problem. This helps workers focus their efforts on where repairs are needed, ensuring that the pavement meets the required standards for smoothness and quality. By clearly outlining this area, it facilitates efficient and targeted repairs, leading to improved pavement performance and longevity.

Other options may relate to maintenance practices but do not accurately reflect the direct purpose of the 50-foot markings in this context. For example, while additional compaction may be needed in some circumstances, the specific marking has more to do with identifying repair sections rather than compaction alone.
