| Abstract | Thailand Department of Highways (TDOH) currently lacks a rigorous system for aggregating various pavement distresses to a combined condition index that can signify an overall distress condition of pavement. This shortcoming inhibits TDOH from ranking pavement sections based on their overall condition as well as developing a pavement deterioration model for long-term pavement management plan. This research presents the derivation of distress aggregation score (DAS) that represents an overall distress condition and pavement performance index (PPI) that reflects an overall pavement performance for TDOH highways. Questionnaire was meticulously developed and distributed to selected pavement experts at TDOH in order to gather expert opinions for deriving DAS and PPI evaluation systems. DAS is a numeric score ranging from 0 to 100 where 0 reflects the worst condition and 100 reflects the best condition. DAS contemplates alligator crack, linear crack, bleeding, edge break, patching, pothole, raveling, rutting, shoulder step, shoulder deterioration and surface deformation in evaluating an overall distress condition. PPI is also a numeric score ranging from 0 to 100 where 0 signifies the worst performance and 100 reflects the best performance. PPI considers DAS, IRI, deflection and skid resistance in evaluating an overall pavement performance. DAS and PPI were used to evaluate four hundred one-kilometer sections of asphalt pavement highways in Saraburi Province though PPI of the pavement sections could not be accurately determined due to the lack of deflection and skid resistance data. DAS and IRI of the pavement sections were then compared with the treatment actions suggested by the HDM-4 analysis. The comparison results show that DAS and IRI were relatively corresponding with the suggested treatment actions. The relationship between IRI and overall distress condition of the pavement sections was also examined using multiple regression technique where IRI was dependent variable and distresses were independent variables. Nevertheless, the multiple regression statistics result reveals that IRI has rather weak relationship with an overall distress condition. |
