Consideration of Fatigue Resistance Tests Variability in Pavement Design Methodology

Abstract

The article is focused on the description of a road pavement design procedure and introduces a specific method of considering the repeatability and reproducibility of the fatigue resistance test. An example is taken from the Czech Road Pavement Design Methodology pursuant to TP 170 (2004, Navrhova´nı´ Vozovek Pozemnı´ch Komunikacı´, Ministry of Transport, Czech Republic, available from: http://www.pjpk.cz/TP%20170.pdf). The article draws on foreign experience in the consideration of fatigue resistance in France and the USA, and the objective of the designed methodology is to bring the results of laboratory tests closer to a specific road pavement design allowing a better distinction in the quality of bitumen mixtures used in the design of road pavements.
