APPLICATION OF THE DIRECT TENSILE TEST TO BITUMINOUS MIXTURES

APPLICATION DE L'ESSAI DE TRACTION DIRECTE AUX ENROBES BITUMINEUX

The author presents a theoretical study of linear and non-linear viscoelasticity and presents the results obtained with tensile tests carried out on various road mixtures from sand-bitumen to asphaltic concrete containing modified binders. These tests cover small deformations up to failure, at different temperatures and rates of applied stress. Correlations are established between tensile characteristics and results of fatigue tests conducted on the same materials. The best correlation is obtained for tensile tests at 0 deg C and slow rates for the different types of mixtures tested. Details are given of the simplified test procedure adopted, and it is shown how this test can be used to determine the fatigue behaviour of bituminous mixtures in the case of a two-course and three-course structure and how it does contribute to the study of the mix-design of bituminous mixtures. /TRRL/ covering abstract, see IRRD abstract no 107043.
