Abstract
A process for preparing compounds of bitumen and polymers, comprising mixing 80 to 98% by weight of a bitumen having a penetration of from 30 to 220 with 2 to 20% by weight of a styrene-diene conjugated block copolymer having a mean molecular weight of from 30,000 to 300,000, with agitation, at a temperature of 130 to 230 DEG C, maintaining the resulting mixture at this temperature for at least 2 hours and then adding 0.2 to 3% of elemental sulphur, based on the weight of the bitumen, while maintaining the same agitation and temperature conditions for at least a further 20 minutes, characterised in that the conjugated diene component is carboxylated butadiene or isoprene. These compounds are useful for surfacing roads, and have various industrial applications, e.g. waterproofing.
