“…In Figure 3 there is an evaluation of the same parameter of Rut depth as a next step of operational serviceability modelling where a growth of the Rut depth parameter is evaluated as a relative value by Equation (7). Such degradation function of Rut depth obtained from APT was already partly presented in several studies [2,43].…”

The article presents a comprehensive asset management method. Here presented method aims to bridge the economic approach to asset management with the technical approach to road infrastructure life cycle, namely its resilience and performance. The presented asset value calculation methods are based both on socio-economic viewpoints on community benefits of an asset, as well as the technical aspect of the technical condition and residual life calculations of a road infrastructure. In contrast to common road asset management methods, asset value is not arbitrarily annually depreciated, instead, it is exactly calculated based on pavement performance models, pavement construction fatigue and paving material properties. Road asset value calculation is based on the asset performance and the technical condition of a pavement structure and other objects. Road asset performance is defined in terms of society and road user demands put on road category and its qualitative standard. Road asset technical condition is evaluated by the procurement cost calculation and condition deterioration. Value of condition deterioration is defined by residual life expectancy based on fatigue and construction reliability of the road infrastructure. The cross-asset allocation method is used for the creation of programs for claim and allocation of funding. The aim was to increase the credibility of the road administrators with the public as they present their decisions based on road asset management, and to increase the level of acceptance for practitioners.

“…The principle of accelerated pavement testing is an application of artificially induced load applied in a short period of time on an experimentally built road section. Such facility simulates a real load on the real pavement while providing great control during the experiment, this allows researchers to evaluate different factors of road deterioration throughout the pavement life cycle [19,20].…”

“…APT is essentially a laboratory test (Figure 1) at a scale of 1:1, during which a load unit (in our case, a semi-axle of a heavy vehicle) is used to induce a load at a frequency that simulates road performance in a relatively short time, which would otherwise be distributed throughout its whole life cycle [20].…”

“…that simulates road performance in a relatively short time, which would otherwise be distributed throughout its whole life cycle [20]. The degradation characteristics obtained experimentally were derived from data collected at the APT facility; the construction and operation parameters of the facility are presented in detail by Mikolaj et al [21].…”

Economic Impact Analysis of the Application of Different Pavement Performance Models on First-Class Roads with Selected Repair Technology

et al. 2021

Mathematical expression of the deterioration of individual pavement parameters is, from the point of optimal repair and maintenance strategy decision-making process, an important part of the application of any pavement management system (PMS). The reliability of individual PMS depends on the quality of the inputs and the reliability of its internal sub-systems; thus, deterioration equations derived from high-quality input data play pivotal roles in a system for the prediction of the pavement life cycle. This paper describes the application of pavement performance models within pavement life cycle analysis (LCA) with the use of the integrated system of economic evaluation (ISEH), which is a calculation tool used for first-class roads with a standardized pavement composition of asphalt binders, where changes in operational capability parameters are modeled using individual model simulations. The simulations presented in this paper demonstrate changes in main economic indicators (net present value and internal rate of return) on two different pavement performance models. Both simulations share the same input parameters (traffic intensity, construction intervention, maintenance costs, discount rate) but differ in deterioration evaluation, all of which were applied to each model (a total of five models).
