How are pavement performance and maintenance assessed?

Pavement performance and maintenance are commonly assessed through visual inspections and evaluations. This method allows inspectors to directly observe the condition of the pavement, identifying surface distresses such as cracking, rutting, raveling, and other wear and tear that can occur over time. Visual inspections are essential as they provide immediate feedback on the pavement's structural and functional integrity.

This approach can involve the use of standardized rating systems that help quantify the observed conditions, which is important for establishing a baseline and guiding maintenance decisions. Inspectors can employ tools like gauges and measuring instruments to assist in the evaluation process, but the foundational assessment relies heavily on the trained eye of the inspector to recognize patterns and severity of distress.

While other methods, such as automated monitoring systems or predictive analysis, can complement pavement assessments, visual inspections remain a primary technique in the industry due to their directness and cost-effectiveness.
