Journal Title:ACEE International Journal on Civil and Environmental Engineering

Roughness is good evaluator of performance of road. This paper presents a case study of IRI (International Roughness Index) estimation at NH 67 during four laning of Trichy - Tanjavur section. An attempt has been made to evaluate the IRI of construction work zones using Levenberg- Marquardt back-propagation training algorithm. A MATLAB based model is developed, and the data from the case study are used to train and test the developed model to predict IRI. The models performances are evaluated through Correlation coefficient (R2) and Mean Square Error (MSE).
