Abstract
Plastic bituminous compositions comprising (a) 100-30 % w of a mixture of 1. 45-99.8 % w of a bituminous component having a penetration of less than 800 (0.1 mm) at 25.degree. C., 2. 0.1-30 %w of a lithium salt of a C.sub.10 -C.sub.40 (hydroxy) fatty acid, and 3. 0.1-25 %w of a thermoplastic polymer, and (b) 0-70 %w of a filler having excellent self-adhesive properties even when applied on wet or wetted surfaces. They are cold applicable and shear-stable.
