Abstract
El siguiente informe analiza el comportamiento de mezclas con graduación discontinua con el fin de generar especificaciones enfocadas en mezclas más resistentes a la deformación permanente.
El estudio consta de 3 fases, la primera y segunda ya finalizaron y se trabaja en la tercera. Se trabaja según la metodología Marshall y los especímenes se prueban en la pista de ensayo del laboratorio (APA).
De la segunda fase se concluye que el desempeño de la mezcla no es susceptible a pequeñas variaciones en el contenido de polvo y se recomienda el uso de un aditivo que mejore la resistencia a la deformación.
The following report analyzes the behavior of mixtures with discontinuous grading in order to generate specifications focused on mixtures more resistant to permanent deformation. The study consists of 3 phases, the first and second are finalized and the third still in progress. The mix design is made according to the Marshall methodology and the specimens are tested in the laboratory test track (APA). From the second phase it is concluded that the mixture performance is not susceptible to small variations in the dust content and the use of an additive that improves the resistance to deformation is recommended.
