• Study on the accuracy of axle load spectra used for pavement design

  Publikacja

  • D. Ryś
  • P. Burnos

  - International Journal of Pavement Engineering - Rok 2022

  Weigh-in-Motion (WIM) systems are used in order to reduce the number of overloaded vehicles. Data collected from WIM provide characteristics of vehicle axle loads that are crucial for pavement design as well as for the development of pavement distress prediction models. The inaccuracy of WIM data lead to erroneous estimation of traffic loads and in consequence inaccurate prediction of pavement distress process. The objective of...

• Structural design and sensitivity analysis of semi-rigid pavement of a motorway

  Publikacja

  • J. Judycki
  • P. Jaskuła

  - Rok 2011

  This paper presents application of mechanistic-empirical methods in design of semi-rigid pavement for a section of a motorway in Poland. The stage construction was assumed. Three fatigue criteria were applied in the design. For asphalt fatigue cracking and subgrade soil the criteria from the Asphalt Institute (USA) were applied. For fatigue cracking of cement stabilized bases the Dempsey (USA) and De Beer (South Africa) criteria...

• Structural Design and Sensitivity Analysis of Semi-Rigid Pavement of a Motorway

  Publikacja

  - Rok 2012

  This paper presents application of mechanistic-empirical methods in design of semi-rigid pavement for a section of a motorway in Poland. The stage construction was assumed. Three fatigue criteria were applied in the design. For asphalt fatigue cracking and subgrade soil the criteria from the Asphalt Institute (1981) were applied. For fatigue cracking of cement stabilized bases the Dempsey (1984) and De Beer (1992) criteria were...

• Consideration of dynamic loads in the determination of axle load spectra for pavement design

  Publikacja

  • D. Ryś

  - Road Materials and Pavement Design - Rok 2021

  Axle load spectra constitute a crucial part of the data for pavement design and pavement distress analysis. Typically, axle load spectra represent static load from vehicles and do not include dynamic loads generated by vehicles in motion. While dynamic loads can significantly contribute to faster pavement distress, this fact is mostly omitted in pavement design methods. The paper presents a methodology for consideration of dynamic...

• Analysis of pavement structure sensitivity to passage of oversized heavy duty vehicle in terms of bearing capacity

  Publikacja

  • D. Ryś
  • P. Jaskuła

  - IOP Conference Series: Materials Science and Engineering - Rok 2018

  Oversized heavy duty vehicles occur in traffic very rarely but they reach extremely high weights, even up to 800 tonne. The detrimental impact of these vehicles on pavement structure is much higher than in case of commercial vehicles that comprise typical traffic, thus it is necessary to assess the sensitivity of pavement structure to passage of oversized vehicles. The paper presents results of sample calculations of load equivalency factor...

• Novel structure and design of compact UWB slot antenna

  Publikacja

  • A. Bekasiewicz
  • S. Kozieł

  - Rok 2016

  In this paper, a novel structure of a compact UWB slot antenna is presented along with a simulation-driven design optimization algorithm for adjusting geometry parameters of the device. Our primary objective is to obtain small footprint of the structure while maintaining its acceptable electrical performance. It is achieved by introducing sufficiently large number of geometry degrees of freedom, including increased number of parameterized...

• A structure and design of a novel compact UWB MIMO antenna

  Publikacja

  • S. Kozieł
  • A. Bekasiewicz

  - Rok 2016

  In the paper, a concept and design procedure of a novel compact MIMO slot antenna is presented. In order to achieve a better filling of available space, individual antennas are constrained to a triangular shape and optimized for a reduced size. The MIMO structure is then assembled using the two of previously designed antennas in orthogonal arrangement. Surrogate-assisted numerical optimization involving variable-fidelity electromagnetic...
