LABORATORY STUDY OF THE MECHANICAL CHARACTERISTICS OF BITUMINOUS MIXTURES

ETUDE EN LABORATOIRE DES PROPRIETES MECANIQUES DES ENROBES BITUMINEUX

This article presents results of laboratory tests recently conducted at the LCPC. Part 1 analyzes the main results of complex modulus and fatigue tests obtained on the main types of bituminous mixture, on mixtures containing modified binders and on mixtures to which industrial waste products had been added. The influence of the temperature and the role of compaction are stressed. A review is presented of the practical means known at the present time of improving the mechanical characteristics vis a vis those 2 parameters. Part 2 outlines a direct tensile test recently developed at the LCPC where an attempt was made to reproduce in the laboratory stress similar to the real extension occurring in the lower part of a flexible pavement. The various phases of the test can be carried out on the same sample and supply results on modulus values, loss of linearity and failure characteristics. (TRRL)
