Abstract
A bituminous building sheeting which is compatible with hot mopping bitumen and bituminous cold adhesives and whose covering mass is modified with APP and IPP. The mass, homogenized under high shear forces is cooled off after the application of 180.degree. to 200.degree. C. at a cooling speed of not more than 120 K/min. Polymer spherulites form on the surface thereby which improve the adhesiveness and prevent oily components from exuding out of the bitumen.
