Ocena skuteczności stosowanej metodyki regulacji osi toru kolejowego
PublikacjaW pracy pokazano przykłady stwierdzonych nieprawidłowości w ukształtowaniu torów kolejowych w płaszczyźnie poziomej. Jako przyczynę istniejącej niekorzystnej sytuacji wskazano stosowaną przez wiele lat metodykę regulacji osi toru. W celu oceny skuteczności tego procesu przeprowadzono dwie kampanie ciągłych pomiarów satelitarnych. Pierwsza kampania pomiarowa miała na celu identyfikację stanu istniejącego, druga zaś − określenie...

Evaluation of Asphalt Mixture Low-Temperature Performance in Bending Beam Creep Test
PublikacjaLow-temperature cracking is one of the most common road pavement distress types in Poland. While bitumen performance can be evaluated in detail using bending beam rheometer (BBR) or dynamic shear rheometer (DSR) tests, none of the normalized test methods gives a comprehensive representation of low-temperature performance of the asphalt mixtures. This article presents the Bending Beam Creep test performed at temperatures from −20...
