Abstract

Betunes modificados con polietileno estables al almacenamiento. Se describen betunes modificados estables al almacenamiento formulados con un betún o mezcla de betunes, un polietileno o mezcla de polietilenos y un compuesto de fósforo que mejora la estabilidad al almacenamiento del sistema. El compuesto de fósforo se elige entre el ácido ortofosfórico, el acido polifosfórico, el pentóxido de fósforo, o mezclas de dos o más de ellos. El polietileno puede ser un polietileno de alta densidad, de baja densidad o reciclado de cualquier densidad e indice de fluidez o una mezcla de polietilenos con diferentes densidades e indices de fluidez mezclados entre sí en cualquier proporción. Los betunes así formulados presentan estabilidad al almacenamiento según la normativa española y son útiles para su uso en mezclas bituminosas para carreteras resistentes a las deformaciones plásticas.
