Preparation of a masterbatch of diene elastomer and silica including preparing at least one silica dispersion in water; bringing into contact and mixing an elastomer latex and the aqueous silica dispersion in the presence of a calcium salt in order to obtain a coagulum; and recovering the coagulum and drying the recovered coagulum in order to obtain the masterbatch. The molar content of calcium cations, defined as the number of moles of calcium cations of the calcium salt per BET unit area of the silica, is between 1.19*10−6 and 2.81*10−6 mol/m2.
