EVALUATION OF MAINTENANCE COSTS FOR THE ROADWAY MAINTENANCE AND REHABILITATION ANALYSIS APPLICATION (ROMARA) IN THE PROVINCE OF ALBERTA

摘要

Maintenance management systems can identify the most cost-effective maintenance treatments at the most appropriate time in the pavement life cycle. Pavement maintenance models can be developed to determine the impact and cost of the treatments and their impact on pavement serviceability. Agencies are examining the cost effectiveness of maintenance and its role in life cycle cost analysis (LCCA). Privatization has made maintenance activities a 'line item' in the operating budget, highlighting maintenance costs and providing a mechanism for tracking activities. The implementation of the Infrastructure Management System (IMS) and Roadway Maintenance and Rehabilitation Application (RoMaRa) in Alberta has resulted in surface condition data and maintenance work orders being allocated to the same highway kilometer point for the first time. This paper explores the potential for modeling of maintenance costs as a function of a pavement performance index. While RoMaRa can be used to calculate maintenance costs as part of the Life Cycle Costs of competing rehabilitation alternatives, no location based data was available until recently. Various trends in performance will be presented. The methodology could be applied to other areas in Canada considering calibrated maintenance cost models as a function of pavement performance indices.
