Summary: | Uncertainty about the remaining service life of the pavement occurs in developing countries even though the structure is designed with the planned life. As a result, there is damage to the network and the structure and function of the road. Uncertainty in volume, traffic growth that exceeds the plan, and limited funds have a very strong influence on the
shape of the road. This study aimed to determine the condition of the road surface and road service functions to find out the service life of the pavement and the relationship between the Present Serviceability Indexvalue and the International Roughness Index on the flexible pavement.
Secondary data collection such as IRI and traffic volume is used for modeling and reviewing road service functions. The results show that the remaining road life will end in year 8, a 2-year decrease from the 10-year plan. The relationship between PSI and IRI plans has an R2 value of 0.9981, while the actual condition has an R2 of 0.9976. |
