Structural and functional prediction of pavement condition (A case study on south arterial road, Yogyakarta)

Pavement conditions will reduce the level of service over time. It is characterized by the occurrence of structural damage of the road pavement layers in which the neglect for a long period can worsen the condition of the pavement layers that can affect the traffic safety and comfort. Road pavement performance is determined based on the requirements of the functional and structural condition. The functional conditional requirements relate to roughness, pavement surface aggravation, while the structural condition requirements relate to the pavement strength or carrying capacity in serving the load and the traffic flow. The aim of this research is to evaluate the functional and structural of the flexible pavement on south arterial road in Yogyakarta and to provide recommendation of maintenance and rehabilitation. The functional evaluation of pavement is based on DGH and PCI method, which combines International Roughness Index (IRI) and Pavement Condition Index (PCI) values, while structural pavement evaluat...
