Pavement Evaluation Using Falling Weight Deflectometer (FWD)
Pavements are the key elements for a country’s infrastructure, and therefore its periodic evaluation, maintenance and rehabilitation activities are important. In the present study, a State Highway (SH) connecting Harihara to Honnalli, Karnataka was selected with a length of 40 km for evaluation. Road inventory survey, soil characterization and FWD studies were carried out along the selected stretch of the road. Functional evaluation was performed based on manual measurements and rated based on PCI values. The structural evaluation was performed using the modulus values obtained from Falling Weight Deflectometer (FWD). Pavement distresses were identified and maintenance measures were prioritized. Also, a comparison of CBR- and FWD-based modulus methods is also reported. It is concluded that insufficient thickness is the major reason for the failure which has to be corrected by considering overlay and strengthening measures.
