Evaluation of the condition of flexible pavements using the PCI index and automated inspection techniques: study on a mountain road Universidad Tecnológica del Perú UTP - (PE), Perú This paper evaluates the surface and functional condition of the flexible pavement on the Cutervo–Cochabamba subsection (Peru) using laser-based technologies, applying the Pavement Condition Index (PCI) and the International Roughness Index (IRI) in compliance with ASTM D6433-07 and E950 standards. The Laser Crack Measurement System (LCMS) was employed to automate distress detection and provide accurate longitudinal profile measurements. Results indicate that 85.1% of the pavement is in “Very Good” to “Excellent” condition. However, certain segments exhibited severe distresses, and some average IRI values exceeded 3.5 m/km, potentially compromising ride comfort and user safety. Consequently, a road maintenance plan is proposed, prioritizing interventions such as asphalt slurry sealing, crack sealing, and localized resurfacing, with an estimated investment of USD 1.84 million. This approach, grounded in non-destructive inspection technology and objective data, supports optimized pavement management, extends service life, and enhances road performance. It also offers a replicable methodology for high-altitude road infrastructure in similar contexts. | |
