Method for the production of cross-linked and/or functionalized bitumen/polymer compositions and use of said compositions in coverings

   
   

Compositions produced by forming a homogenous mass consisting of a bitumen matrix wherein a cross-linked and/or functionalized elastomer produced in situ from a precursor elastomer is dispersed in a uniform manner and makes up 0.5-30% of the weight of the bitumen matrix. The bitumen matrix is created by associating 95%-20 wt. % non oxidized bitumen having a penetrability of 20-900 and 5-80 wt. % oxidized bitumen having a penetrability of 10-90. The compositions can be used as bitumen binders in the production of coverings.

Las composiciones producidas formando una masa homogenous que consistía en una matriz del betún en donde haber reticulado y/o functionalized el elastomer producido in situ de un elastomer del precursor se dispersan de una manera uniforme y hacen para arriba 0.5-30% del peso de la matriz del betún. La matriz del betún es creada asociando 95%-20 del betún no oxidado de los pesos % que tiene un penetrability de 20-900 y 5-80 del betún oxidado de los pesos % que tiene un penetrability de 10-90. Las composiciones se pueden utilizar como carpetas de betún en la producción de cubiertas.
