• Uses and Applications
• Road Roughness Assessment
• Measures longitudinal pavement irregularities to support evaluation of road riding quality.
• Pavement Condition Monitoring
• Provides quantitative surface profile data for monitoring pavement performance and deterioration.
• Road Maintenance Planning
• Supports prioritization of pavement rehabilitation and maintenance activities.
• Infrastructure Quality Assessment
• Provides road profile measurements for engineering inspections and construction quality evaluations.
• Road Asset Management
• Supports pavement management programs and long-term road infrastructure monitoring.
• Typical Survey Outputs
• Longitudinal road surface profile data
• Pavement roughness indicators, including International Roughness Index (IRI) where supported
• Survey reports and pavement condition interpretations
• Technical Note
• Measurement accuracy, survey speed, IRI reporting, and compliance with applicable testing standards depend on the specific equipment configuration, calibration, survey procedures, and processing software.
