A raw elastomeric composition in free-flowing pellet form is described, which comprises a raw elastomer with molecular weight from 50,000 to 400,000 Da, and an anti-block agent comprising inorganic fillers, capable of forming emulsions in water. Likewise, a process for obtaining said raw elastomeric compositions in free-flowing pellet form, comprising the steps of: a) polymerizing at least one monomer through solution polymerization in order to obtain elastomer crumb; b) forming an aqueous suspension of the elastomer crumbs; c) dewatering the aqueous suspension; d) adding an anti-block agent comprising inorganic fillers capable of forming emulsions in water; e) drying the dewatered suspension; and f) pelletizing the elastomer to form a raw elastomeric composition in free-flowing pellets form. The raw elastomeric composition in free-flowing pellets form thus obtained can be used as an adhesive composition, in asphalt modification and in asphalt emulsions.
