Evaluación de parámetros de resistencia y calidad de un pavimento flexible elaborado con una mezcla asfáltica SMA (Stone Mastic Asphalt)

Abstract

This article will deal with the evaluation of the strength and quality parameters of the SMA asphalt mixture. It is a type of discontinuous mixture that increases the useful life of the wearing layers, since it has a high content of binder, high quality aggregates, filler and cellulosic fiber, thus achieving an effective mineral skeleton. From the characterization of the materials of both the aggregates and the AC-20 asphalt, it is expected to determine that they are of good quality. The characterization of the aggregates will be carried out through the following tests and following their respective standards: Homogenization and Reduction, Granulometry, Relative Density, Degradation of the Coarse Aggregate. On the other hand, the tests to be carried out with AC- 20 Asphalt are: Penetration, Ductility, Flash Point, Softening Point and Kinematic Viscosity. After determining that the materials are of optimal quality, they can be used in the design of the SMA mixture and in the subsequent manufacture of specimens in order to evaluate the strength and quality properties of SMA.
