BITUMEN/POLYMER COMPOSITION CURABLE AT TEMPERATURES LOWER THAN 100 DEG C, PREPARATION AND UTILISATION THEREOF

摘要

A bitumen/polymer composition is comprised of a bitumen, an elastomer polymer which is sulphur-curable in a quantity representing from 0.5 to 20 % by weight of the bitumen, a sulphur-donor curing agent, a curing accelerator and a viscosity reducing agent selected from water and hydrocarbonated oils. The curing accelerator present in the composition comprises one or a plurality of curing accelerators which are active at temperatures lower than 100 DEG C and the viscosity reducing agent is used in a quantity appropriate to fluidify the composition at temperatures lower than 100 DEG C.
