This survey provides the discrete elevation profile along the left and right sections of the surveying vehicle. The data from several overlapping sections are used to define the longitudinal profile. The characterization of the pavement roughness is based on the longitudinal profile and multiple methods are available for the characterization. For instance, Picornell‑Darder (1985) employed the amplitude spectrum, serviceability index, and distribution of bump sizes. This method is suitable for the quality assurance during the service period.</p><p><strong>Accuracy and Precision</strong></p><p>The level surveys can be an accurate method. However, the pavement roughness characterization may vary with the interpretation methods.</p><p><strong>Adequacy of Coverage</strong></p><p>Level surveys can be used to cover a large section of pavements within a reasonable time.</p><p><strong>Implementation Requirements </strong></p><p>A profilometer is required for the survey.</p><p><strong>General Comments</strong></p><p>The level survey is a commonly used quality assurance method for the partial encapsulation technology.</p></p>
