Abstract
The invention relates to a method of making a theremorevsible bituminous composition. The method includes transferring an additive to a bitumen to form a mixture, and stirring the mixture until its appearance is homogenous. The additive can be an organogelator with general formula R″—(COOH), where R″ is a linear or branched, saturated or unsaturated chain having 4 to 68 carbon atoms and z is an integer varying from 2 to 4. The bituminous composition is hard at the temperature of use without increasing its viscosity when hot.
