The invention relates to a method for producing foam bitumen from bitumen, water and additives. The invention is characterised in that at least one silicon compound of general formula (I) is applied as an additive, wherein R, R<1> and R<2> can be the same or different in the average molecule and represent an alkyl radical with 1 - 30, preferably 8 - 22 carbon atoms or the radical Z- (-CnH2nO-)mR3, whereby R3 is a hydrogen radical or an alkyl radical having 1 - 8 carbon atoms, Z is a bivalent radical of formula O-, - (CH2)p-O- or CH2-CH(CH3)-CH2-O- where p = 2 - 6, n has an average numerical value of 2.7 4.0, m has an average numerical value of 5 - 130, a and a' together have an average numerical value of 4 -1500, b and b' together have an average numerical value of 0 - 100 and c and c' together have an average numerical value of 0 - 50. |
