PROCESSO PARA A PREPARACAO DE COMPOSICOES DE BETUME

摘要

The present invention provides a process for preparing a bitumen composition which comprises mixing at an elevated temperature an oxidised bitumen having a penetration index of at least 0 with a thermoplastic rubber which is present in an amount of less than 5% wt., based on total bitumen composition; bitumen compositions obtainable by such process; and the use of such bitumen compositions in asphalt mixtures for road applications.
