Description of the research topic:
Pavement Management Systems represent a financial and technical optimization process which creates an adequate register of technical data on the road network in question, and after a multi-criteria analysis of these data gives an optimal offer to the decision maker and the operator as for how to rank the planned interventions and also the technical depth of them. Among the elements of public road network urban road structures are exposed to significantly different effects than those of nationwide road network, since they are characterized by a differing size and intensity of traffic and a differing road structure, therefore they demand a different renovation technology.
The implementation’s requirement of all PMSs is appropriate quantity and quality data collection and the analysis following and to this must apply those processes and geoinformatics devices which are suitable to measure the urban roads condition characteristic. After the recognition of the road network condition characteristic would be define so-called degradation curves, with which we assay forward the future characteristic of the road network. Often lack of data makes it difficult to determinate the degradation curves therefore the clarifications of the data collecting process would be necessary. During data collection the most innovated geo-informatics solutions must be presented and adapted. When demonstrating deterioration processes, it is needed to examine the historical deterioration data of road network, and also to make an offer as for how to extend these deterioration parameters to the whole of the road network in the most effective and correct way.
Nowadays any infrastructure maintenance is unthinkable without asset management, which helps the decision making and makers. And these kind of engineering problems have been resolved by multi criteria optimization methods.
While the doctoral applicant working on this topic, he must show more multi criteria optimization methods and separately it is worth dealing with the effects of the pavements strengthening on the road sections’ renovations ranking.
The aim of the doctoral topic is to create an up-to-date urban PMS with taking the urban characteristics into consideration, building upon the knowledge of previous urban pavement management systems, and using the correct deterioration and optimization processes.
The doctoral candidate is assigned to conduct research in urban pavement management systems with regards to the following subtopics:
• Locating the possibilities of developing the evaluation of the state of urban pavements. (To facilitate the measurement method of uneven surfaces with using GIS.)
• Examining the deterioration of urban pavements, defining the trends of deterioration. (It is necessary to develop a network behaviour model based on the time-series results of different types of dynamic and quasi-static load-bearing and surface-unevenness.)
• Creating reference sections of urban pavement deterioration. (Creating urban reference sections based on long-term condition monitoring, which take the followings into account: the specialities of traffic load in cities, the public utility network and the characteristics of urban drainage and earthworks.)
• Ranking the offers for urban renovations. (Applying different optimization methods for defining technical manuals for renovations and ranking.)
