Beschreibung
Zusammenfassung:	The present invention relates to ballast which have a high stability and a long service life and to a process for the production of ballast. These ballast are suitable for railway track laying and road construction and dike systems used for example in costal protection. These ballast comprise ballast stones and polyurethane foams based on a reaction mixture of selected polyisocyanates and selected compounds with isocyanate-reactive groups.
