The United Kingdom Pavement Management System (UKPMS) is a computer system currently being designed for the economic management of the structural maintenance budget of a road network. It is being promoted and funded by most highway authorities in the United Kingdom, representing owners of all classes of roads, from congested city streets to narrow rural roads. It will incorporate a new system of visual data collection, data analysis, and budget allocation for all paved areas within the highway boundary and will combine data from different types of condition surveys. Other significant features include the ability to project condition data into the future; this enables the user to take account of the economics of alternative maintenance treatments when deciding where and what treatments should occur. Because the economics of alternative maintenance strategies are considered, UKPMS is, in essence, prioritizing the solutions to structural road maintenance rather than, as many systems do, prioritizing the problems. To test the innovative principles of UKPMS, and to test the new data collection techniques, prototype software has been written. It is being used by highway maintenance practitioners themselves during the current design stage. The core philosophy of UKPMS is to defer treatments where it is cost-effective and safe to do so and to give priority instead to preventive maintenance. |
