Temperature implications on rheological-mechanical behavior and design of high modulus dense asphalt mix

•A research on the rheological-mechanical behavior of high modulus dense asphalt mix is carried out.•All the materials, parameters and models to formulate the asphalt mix tested are defined.•Complex modulus, fatigue resistance and numerical simulations are the main evaluation scopes.•Critical energy dissipation temperature is a decisive parameter to design asphalt pavements. The main aim of this paper is to evaluate the influence of temperature on mechanical-rheological behavior and design of high modulus dense asphalt mix. Analytical procedures were conceived based on the French rational methodology. The asphalt mix formulated was tested through two point bending complex modulus and fatigue tests. Numerical simulations using Huet-Sayegh viscoelastic linear model and computerized tools Viscoanalyse and Viscoroute were proceeded to design asphalt pavement structures. The results obtained indicate the critical energy dissipation temperature verified in complex plan has decisive influence on the asphalt mix behavior and must be analyzed particularly for designing asphalt pavement structures.
