This paper used research results from renowned foreign and domestic institutes in terms of influence of synthetic fibres from armide and polyoefin family on physical and mechanical characteris- tics of asphalt mixture, firstly in terms of chemical bonding, longevity of use and solidity. The researches show that this is a new technology which provides for formation of 3D reinforcing net in the asphalt, and which has significant effect on increased resistance to permanent deformations, fractures and in- creased resistance with possible decreased thickness of asphalt layer and extended longevity, which provides for important economic benefit. Comparing this asphalt component with conventional we see increased resistance to “road ruts”, sensitivity to water and permanent deformation.
The availability of real-time data on the state of railway facilities and the state-of-the art technologies for data collection and analysis allow transition to the fourth generation maintenance. It is based on the prediction of the facility functional safety and dependability and the risk-oriented facility management. The article describes an approach to assessing the risks of hazardous facility failures using the latest digital data processing methods. The implementation of this approach will help set maintenance objectives and contribute to the efficient use of resources and the reduction of railway facility managers’ expenditures.
