Road Pavement Condition Index Deterioration Model for Network-Level Analysis of National Road Network Based on Pavement Condition Scanning Data

Surveying the condition of pavement is one most important processes in managing road network. The information collected during these surveys allows for calculation Pavement Condition Index, which a derivative cumulative qualitative indicator that evaluates various characteristics and defects. Deterioration modelling measured indicators calculated indices critical element its accurate prediction brings process management closer to higher quality by more efficiently allocating funds repair work. Many different models – both extremely complex simple are used world simulate individual indicators. However, developed based on data certain country or region not suitable another due requirements structures other reasons. In Lithuania, measurements surfaces with new generation survey equipment have been carried out recently but stored databases about sections minimal, it becomes difficult adapt applied abroad missing information. aim this study create index evaluating such quantitative as traffic loads, surface unevenness, type repair, age, climatic zones, construction classes.
