Streszczenie: Asfalt spieniony powstaje po wprowadzeniu do gorącego asfaltu wody i powietrza pod ciśnieniem. Piana otacza kruszywo i szybko rozpada się, pozostawiając na powierzchni lepiszcze. Stosowany jest głównie do recyklingu nawierzchni podobnie jak emulsja asfaltowa. Dotychczas w Polsce nie wykonywano badań materiałów z asfaltem spienionym i nie opracowano specyfikacji technicznych.
Abstract: Foaming asphalt is created by insertion of water and air under pressure to hot bitumen. Foam cover grains of aggregate and it is quickly disintegrating leaving the binder on aggregate. Foaming asphalt is mainly used to recycling of pavement in the same way as asphalt emulsion. Up to now in Poland, neither tests of materials with foaming asphalt have been made nor technical specification elaborated.
