Round Robin Tests on Reflective Cracking Laboratory Tools
Abstract In the context of road network rehabilitation, private companies develop multilayered systems to prevent reflective cracking problems in pavements. These systems are submitted to a mixed mode of cracking propagation due to thermal (mode I) and traffic (modes I and II) effects. In addition, a fatigue mechanism has to be considered under the repetition of these solicitations. In order to evaluate the performances of these anti-reflective cracking systems, several laboratory devices have been developed. In this paper, we focus on two of these tools in order to perform round robin tests on various types of anti-reflective cracking systems. The first test was developed at CEREMA laboratory in Autun (former LRPC). The second was developed at the Ecole de Technologie Supérieure (ETS) in Montréal and is used at Eurovia’s Research Centre in Bordeaux for the purpose of the study. This paper first proposes an analysis of the two test procedures which particularly highlights a main difference in the horizontal and vertical ways of solicitations. Horizontally, a monotonic stretching displacement (mode I) is applied for the first test whereas it is cyclic for the other. Vertically, shear loading (mode II) is applied with the second test device whereas it is flexural (mode I) with the first one. The author’s analysis will focus on seeking correlations between results of the two tests.
