Abstract

L'invention concerne une composition anti-givrage appropriée pour être incorporée dans des conglomérats bitumineux pour pavage routier, comprenant un chlorure de métal alcalin, un carbonate de métal alcalino-terreux, un formiate de métal alcalin ou alcalino-terreux, un polysiloxane et éventuellement un chlorure de métal alcalino-terreux, dans laquelle le polysiloxane est contenu en une quantité se situant entre 0,5 et 2,0 % en poids du poids total de la composition. L'invention concerne également un conglomérat bitumineux conçu de manière à fournir un pavage routier anti-givrage, comprenant des agrégats, du bitume, une charge et de 2 à 6 % en poids d'une telle composition anti-givrage par rapport au poids des agrégats.
