Method for producing modified bitumen with a high elastic relapse

摘要

process for the production of modified asphalt with high elastic rebound is that a mixture of styrene modifying, rubber, sulphur and polymerization initiator nadbenzoesanu t - butyl compared 40: 10: 1: 05, warm for a period of 6 hours at a temperature 60u00b0c and mixes the int ensywnie, after which the mixture at a temperature of range distributes 120u00b0c - 150u00b0c,advantageously 140u00b0c to asphalt 35 / 50 and in relation to a mixture of recasting as 1: 25 and warm for a period of 20 hours.
