MARIN URIBE, Carlos Rodolfo y GUZMAN MELENDEZ, María Rosa. MODELING OF A PAVEMENT STRUCTURE USING DYNAMIC MODULES OBTAINED IN A LABORATORY APPLYING MARSHALL AND SUPERPAVE METHODOLOGIES. Rev. ing. univ. Medellin [online]. 2007, vol.6, n.11, pp. 53-63. ISSN 1692-3324.
The SHRP (Strategic Highway Research Program) through the new design method of hot asphalt mixtures 'Superpave' has promoted the development of researches in order to get more durable and resistant asphalt mixtures that show a superior performance. Then, it is important to know the effort and deformation condition that are produced when modeling a pavement structure with asphalt layers made up of asphalt mixtures designed with different methods (Marshall and Superpave) and therefore, with a different dynamic characterization (fatigue laws, dynamic modules, and deterioration answers). This modeling allows us to have a general idea of the structural capacity to endure traffic throughout its life cycle represented by N value (Number of equivalent loads axis) and perhaps to obtain some hints of possible savings in pavement preservation costs which are basic reasons to support and stimulate the implementation of the Superpave Method as a new design of the hot asphalt mixtures.
