摘要：

In France, mechanical tests are used essentially for characterizing the performance of bituminous concretes for mix design purposes, production control requiring retroaction times that are much too short. A new test has been developed to measure stiffness moduli and to estimate fatigue properties. Secant moduli at different temperatures, linearity loss, and strength at 0 degree C are determined by a full tensile test on each sample. An estimate of the bending fatigue curve at 10 degree C is obtained by two regressions. For the mix design, the diversity of functions to be provided and the cost of testing make it necessary to rank the problems according to importance and to define a methodology that can be adapted to different cases.
