Which tool is an alternative option for measuring pavement smoothness in North Carolina?

The North Carolina Hearne Straightedge is a specialized tool uniquely designed to measure pavement smoothness according to the standards and practices adopted in North Carolina. It allows for precise measurement of variations in pavement surface, which is crucial for ensuring a smooth ride quality on roadways.

This tool is particularly effective in identifying surface irregularities, and its use aligns with local standards and regulations for road construction and maintenance, making it a relevant and practical option for pavement smoothness assessment within the state.

While other options may also be used to assess pavement conditions, they either do not comply with specific state requirements or are less practical for measuring smoothness in the same context. This makes the Hearne Straightedge a fitting choice for the unique needs of pavement measurement in North Carolina.
