Indeed, in the sizing of pavements in the USA, the prediction models used in the calculation of the dynamic mod- ulus of HMA are not adapted to the characterization of the mineral skeleton of the HMA mix designed with the French method. This article aims to assess the predictive models of the dynamic modulus used in the mechanis- tic-empirical design for their use in the design of bituminous pavements, and to develop new predictive models taking into account the sieve series LC and AFNOR standards. A total of six types of mixtures were subjected to the de- termination of complex modulus testing by direct tensile-compression on cy- lindrical specimens (26-700 LC) over a temperature range (5) and frequency (5) data. Dynamic modulus prediction models |E*| are studied Witczak model 1999 and model Witczak 2006. These models do not take into account the AFNOR or LC mesh sieve, an approach was made in relation to the US mesh sieve to replace ρ 200 (0.075 mm), ρ 4 (4.76 mm), ρ 38 (9.5 mm) and ρ 34 (19 mm) respectively by the AFNOR mesh P 0.08 (0.08 mm), R 5 (5 mm), R 10 (10 mm) and R 14 (14 mm). The result is the production of two models whose are evaluated by correlation with the values |E*| of modulus measured in the laboratory is satisfactory (R 2 = 0.83 respectively R 2 = 0.71 and p-value = 0.00). The optimi- zation of these approximate models gave new models with the same frame as the original models and a better correlation with the data observed in the la- boratory (respectively R 2 = 0. 95 and R 2 = 0.91 p-value = 0.00).
