THE BEHAVIOUR OF BITUMINOUS MIXES IN SIMPLE TENSION

COMPORTEMENT EN TRACTION SIMPLE DES ENROBES HYDROCARBONES

A simple tensile test is proposed for the determination of characteristics which would facilitate the design of pavements from the point of view of failure, or the study and control of the materials from the viewpoint of a specific use. The author examines first different mechanisms of deformation of granular media with bituminous binders in order to have a more comprehensible base for the establishment and the interpretation of a non-linear law of behaviour. This law was established in the case of refined tests which make it possible to define the standards. On the basis of relatively extensive studies carried out on a group of very different formulae, the author has defined a procedure for simplified tests. He also seeks to establish a multiple linear correlation between fatigue tests and tension tests where use is made particularly of a factor of non-linearity serving as a measure of damage in the test with a single loading. The different formulae are compared within the framework of a model of a two course pavement or a sub-grade and the external stresses are invariable; the modulus and the allowable deformation in fatigue make it possible to calculate the thickness of the surfacing. The tensile test is then applied to the study of some formulation parameters. /TRRL/
