In the Federal Republic of Germany the design of a new, complete pavement management system (PMS) is under way. Major components are already operational. Meanwhile, data on road conditions have been collected with high-speed monitoring systems for approximately 20,000 km of German autobahn lanes. The data were assembled according to evenness, skid resistance, and surface damage and subsequently classified via a special grading system. By applying special algorithms, a service value, a structural value, and an overall condition value were developed. The results of the survey can be presented in lists, route section graphs, and network graphs with different colors indicating where specific target, warning, and threshold values are exceeded. By means of continuous feedback, the information collected is used to improve and adjust the system's components and the plausibility of the output. There is agreement that for an effective PMS application, repeated automated network monitoring is necessary. To minimize necessary monitoring and evaluation efforts, the use of multifunctional automated monitoring systems is envisaged, which will collect all necessary data during a single pass. Fully automated operation with direct computerized evaluation is necessary here. The structure of the overall PMS and its major components is outlined. |
