| Popis: | Pavement evaluation is conducted to assess the functional and/or structural condition of existing pavement systems which can be done on project or network levels. Through pavement condition assessment, pavement deterioration models can be established and thus maintenance and rehabilitation alternatives can be proposed. The prediction of pavement performance which is primarily based on the pavement evaluation results is a critical element of a successful pavement management system (PMS). The main objective of this research is to revise and modify the current pavement condition rating (PCR) method for pavement evaluation as a major component of an effective PMS for roads and transport directorates in Egypt. Pavement condition data were collected from literature, General authority of roads, bridges and land transport in Egypt and the long-term pavement performance (LTPP) database. Due to its accuracy, only the LTPP data were used to modify the current PCR method to yield comparable values to the very well-known pavement condition index (PCI). The proposed modified PCR was validated using pavement distress data collected from two rural roads in Egypt, and the data showed reasonable accuracy as compared to the PCI method. |
