Influences and interactions of the surface quality and the bearing capacity on the intrinsic value and the user value (VSS2004/713)
Overview
Objectives:
This research has as a principal objective to bring bases to improve the differentiated taking into account of the various parameters of state at disposal in calculation of a value representative of the deficit of total value in term of need for maintenance. The relative importance of the various parameters and their sensitivity compared to the need for possible maintenance works will have to be studied. The systematic employed will have to also allow to apprehend in monetary form the immediate or future costs of maintenance works to be envisaged.
The final aim of this research is to allow by one or various methods to apprehend the optimal succession of measurements of maintenance from an economic point of view and to allow there, the determination of investment and action plan in the short or the long term.
Methodology:
The following steps will be provided during the project:
- Analysis and synthesis of references cited in the schedule as research bases
- Analysis and synthesis of possible relationships between the different available status indicators and their significance and importance to the choice of a particular measure of maintenance
- Analysis of a state panel survey data recently made by ACSS and Infralab (about 1000 km of urban roads, cantonal roads and highways) to identify potential interactions and relationships between surface damage and lift
- Analysis and proposals for the determination of generic values describing the road structures from a "heritage" (intrinsic value), an optical "Users and Security" (use value) and a "maintenance" optics
- Analysis of medium and long-term monetary influences related to the choice of the type of maintenance measure.
