Calculation of Aggregate Pavement Condition Indices from Damage Data Using Factor Analysis

Calculation of Aggregate Pavement Condition Indices from Damage Data Using Factor Analysis McNeil, Sue Primary Author mixed material bibliography TRB 1991 en English p. 214-222 Trr No. 1311 Pavement Design, Management And Performance Trr No. 1311 Pavement Design, Management And Performance, pp. 214-222 Aggregate pavement condition indices are used by many agencies in the United States and abroad to select maintenance strategies and program network rehabilitation strategies. These indices are usually calculated as weightedsums of several individual damage measurements such as length of transverse cracks, rut depth, and roughness. Existing approaches to condition index calibration are reviewed and a statistical procedure for developing pavement condition indices from distress measurements using factor analysis is described. This method is used to reestimate a condition index from the data collected in the AASHO Road Test for calibration of the present serviceability index (PSI). The new index is compared with the PSI.
