Abstract

The ever-growing requirements for pavements need regular maintenance. Prioritization of pavement maintenance using the multi-criteria-decision-making (MCDM) method is an established method. This study prioritizes roads in Kurukshetra district, Haryana, India, using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Analytical Hierarchy Process (AHP). The variables included in the study are surface distresses (potholes, alligator cracks, longitudinal cracks, ravelling, patch area, bleeding, edge break area, and shoving) and IRI of the pavement. Indian Roads Congress (IRC) standard for prioritization of roads in India is used as a benchmark to compare the ranking provided by both methods. TOPSIS outperformed the two methods, with a Spearman correlation coefficient value of 0.78 and an Index of Agreement value of 0.88. Compared to the IRC method's fixed weight assignment for rank calculation, the TOPSIS method offers a distinct advantage. The TOPSIS approach leads to a more robust and informative prioritization than the IRC method's fixed weight scheme.
