Development of Pavement Maintenance and Management System (PMMS) for Local Streets of Patiala City Using HDM-4

Abstract

The primary objective of this study is to develop Pavement Management and Maintenance System (PMMS) for local streets of Patiala city by using HDM-4 software. 10 road sections were selected for the study after performing traffic survey it was observed that 7 of those roads were having traffic volume less than 6000 AADT and rest of the sections were categorized as medium volume roads with AADT less than 10000. Calibration of HDM-4 deterioration models was also performed in this study and model validation results were found satisfactory with roughness model having R2 of 0.82 and RMSE of 0.29. Road inventory data was collected and pavement condition was assessed using non-destructive testing, visual inspection and Bump Integrator and data inventory was created in HDM-4. Remaining Service Life (RSL) of all road sections was determined showing that road sections are in good conditions. Optimum maintenance and rehabilitation (M&R) activity was assigned to each road section after performing economic analysis of all proposed M&R alternatives, Net Present Value (NPV) to Cost ratio was used for this purpose as well as for prioritizing road section M&R activities. It was seen that road section ‘OC’ had maximum NPV to cost ratio and section ‘TR’ had the least. PMMS created in this study can be applied in practical to utilise the available funds efficiently and effectively benefiting the people and the authorities. The methodology used can be applied to other roads to create their own PMMS and to create a HDM-4 data base to store road and vehicle data
