Abstract

Betunes modificados con polietileno de compatibilidad mejorada.Se describen betunes modificados con polietileno constituidos por un betún procedente de crudos con grados API entre 29 y 44, un polietileno o mezclas de polietileno en un porcentaje comprendido entre el 0,5% y el 49%, entre un 0 y un 8% de un polímero de etileno o etileno-propileno que mejora la compatibilidad del betún y el polietileno, y entre un 0 y un 4% de un sistema que ancle el polímero de etileno o etileno-propileno al betún.Utilizando el diagrama de Cole-Cole se pone en evidencia queestos betunes presentan una compatibilidad mejorada con respecto a otros betunes modificados con polietileno.
