Abstract

Se refiere a un proceso para la produccion de una composicion aditiva destinada a ser mezclada en un conglomerado bituminoso para pavimentacion de carretera, en otras palabras una mezcla de polimeros y aditivos la cual puede ser usada en la modificacion de conglomerados bituminosos, bitumen y productos bituminosos, como membranas bituminosas, para proporcionar resiliencia a las preparaciones bituminosas, partiendo de un material residual mezclado que contiene una mezcla de materiales plasticos, donde la mezcla de materiales plasticos comprende al menos un material plastico basado en un polimero termoplastico de poliolefina, moler hasta un tamano de particula de 20-40 mm, lavar, separar una porcion del material plastico que tiene una densidad promedio de 1.0 kg/m3 o menor y que comprende el polimero termoplastico de olefina, moler la porcion plastica hasta un tamano de particula de 10-20 mm, mezclar esta con PVB y moler adicionalmente hasta un tamano de particula de 4-6 mm. Tambien se refiere a la composicion aditiva obtenible por este proceso.
