ABSTRACT
Abstract I n v e s t i g a t i o n s on the deformation behaviour of a bitumen B 65 and two polymer modified bitumens were c a r r i e d out at extreme temperatures. The low temperature behaviour was derived from s t a t i c creep t e s t s with bituminous mortars at temperatures between -10 and -40 °C. The r e s i s t a n c e against deformation at high temperatures was determined by dynamic loading creep t e s t s with Marshall specimens at 50 and 60 °C. The r e s u l t s allowed a c l e a r d i s t i n c t i o n of the three bitumens and showed the e f f e c t s of the" m o d i f i c a t i o n with polymers. This d i f f e r e n c e was not revealed by the standard t e s t methods.
