Bitumen that is solid at ambient temperature in the form of granules that include a core made of a first bituminous material and a coating made of a second bituminous material, the second bituminous material having a total content of asphaltenes, extracted using n-alkane, of 30% to 50% by weight in relation to the total weight of the bitumen in the coating.

Bitumen solid at ambient temperature

The present invention relates to a material in the form of solid particles consisting of a continuous shell including at least one silicon oxide, said shell confining at least one oil phase, said material being characterized in that said oil phase is solid at the storage temperature of said material and predominately contains a crystallizable oil that has a melting temperature (T) of less than 100&#xb0; C. and at least one substance of interest, and in that the diameter of the particles varies from 1 &#x3bc;m to 1 cm. The invention also relates to a method for preparing said material, to the use thereof for the thermostimulated generation of active substances, as well as to compositions containing same.
