摘要

On the network level, a condition index is used to describe the pavement distress information that could be utilized for thetreatment of pavement conditions in the future. The aim of the present research was to determine the most effective index thatsuits the network of Jazan-a major city in the Kingdom of Saudi Arabia. In this study, four indices, including (1) presentserviceability rating (PSR), (2) present serviceability index (PSI), (3) international roughness index (IRI), and (4) urbandistress index (UDI) were investigated. A comparison between the four indices has been made to determine the most effectiveindex to be adopted by the municipality of Jazan for planning and management of urban roads in the city. The study includesthe data of 10 urban major roads in the city of Jazan, consisting of 18 pavement sections with a total length of 33 km. In theinvestigation, it was found that the correlation between UDI and PSI in measuring the pavement condition is very high (85%),which indicates the reliability of these indices in the measurement of the pavement conditions. Hence, the study recommendsthe PSI as a first choice as it gives reliable information about the pavement condition for urban flexible pavements by usingthree distresses (cracking, patching, and rutting) only. Also, UDI has been recommended as the second choice, which requiresthe survey of all pavement distresses.
