Resumo: The use of ´interlayers´ that tolerate high tensile and shear strain that exists above cracks in deteriorated pavements is becoming an interesting solution to prevent reflective cracking. Recent advances in polymer technology have led to binders that can be used to produce interlayer mixtures with good mechanical properties. In this study, two polymer-modified asphalt binders were evaluated, both from the production of strain relief asphalt mixtures used as interlayers in the field. The binder characterization was presented in two groups: (i) the empirical tests required in the Brazilian specification, and (ii) the rheological properties (frequency/temperature sweep and MSCR tests). Results showed that the difference in rheological properties of the asphalt binder used for strain relief asphalt mixtures did not follow the same difference obtained according to the empirical tests of the Brazilian specification. The G*/sinδ and MSCR parameters (Jnr and percentage of recovery) were able to differentiate the asphalt binders, but the MSCR parameters were more sensitive.

Avances recientes en la tecnología de polímeros han generado ligantes que pueden ser usados para producir mezclas para capas intermedias con buenas propiedades mecánicas. En este estudio, dos asfaltos modificados con polímeros fueron evaluados, ambos empleados en la producción de mezclas asfálticas de alivio de deformaciones usadas como capas intermedias en campo. La caracterización de los ligantes se presentó en dos grupos: (i) los ensayos empíricos requeridos por la especificación brasilera, y (ii) las propiedades reológicas (barrido de frecuencia/temperatura y ensayos MSCR). Los resultados mostraron que el ligante asfáltico usado para las mezclas asfálticas de alivio de deformaciones presentó propiedades reológicas considerablemente diferentes, a pesar de que su caracterización a través de ensayos empíricos es similar. Los parámetros G*/sinδ y MSCR (Jnr y porcentaje de recuperación) lograron diferenciar los ligantes asfálticos, aunque los parámetros del MSCR mostraron mayor sensibilidad.DYNA2018-12-05T13:37:20Z2018-12-05T13:37:20Z2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVASCONCELOS, K.
