Abstract

Procedimiento de fabricación de un betún modificado del grupo BM- 3a ó BM-2, producto así obtenido y sus aplicaciones. El procedimiento comprende la preparación de una premezcla del betún con polietileno de desecho en granza y polvo de neumático triturado como modificadores, en una proporción del 4-8% en peso de polietileno y 2-6% en peso de polvo de neumático, con respecto al peso del betún y a una temperatura de 160-190ºC, seguido de mezclado enérgico de la premezcla en un molino rotor-stator a dicha temperatura, para obtener una mezcla homogénea lista para su empleo en la obra. El betún modificado así obtenido pertenece al grupo BM-3a ó BM-2 (OC 322/97 del MOPU) y tiene su principal aplicación en la fabricación de mezclas drenantes en la construcción de firmes para carreteras.Manufacturing process of a modified bitumen of the BM-3a or BM-2 group, product thus obtained and its applications. The process comprises preparing a bitumen premix with pellet waste polyethylene and crushed tire powder as modifiers, in a proportion of 4-8% by weight of polyethylene and 2-6% by weight of tire powder, with respect to to the weight of the bitumen and at a temperature of 160-190 ° C, followed by vigorous mixing of the premix in a rotor-stator mill at said temperature, to obtain a homogeneous mixture ready for use in the work. The modified bitumen thus obtained belongs to the BM-3a or BM-2 group (OC 322/97 of the MOPU) and has its main application in the manufacture of draining mixtures in the construction of road surfaces.
