Asphalt and polymer mixtures treated with an inorganic acid and cross-linked with sulfur and/or other crosslinkers or accelerators gives a polymer modified asphalt with improved high temperature properties. The acid should be added to the asphalt before the crosslinker.
Selon l'invention, des mélanges de polymères et de bitume traités avec un acide inorganique et réticulés avec du soufre et/ou d'autres agents de réticulation ou accélérateurs permettent d'obtenir un bitume modifié par des polymères présentant des propriétés à haute température améliorées. L'acide doit être ajouté au bitume avant l'agent de réticulation.
