摘要： A bituminous composition, capable of being sprayed at ambient conditions and particularly useful as a soil stabilizer, including, a major proportion of a highly aromatic, bituminous material, such as thermally cracked pitch, in an amount between about 35 percent and 75 percent, a predominantly paraffinic solvent, such as kerosene, in an amount between about 15 percent and 35 percent, a predominantly naphthenic solvent, such as naphtha, in an amount between about 5 percent and 20 percent, and methylene chloride, in an amount between about 5 percent and 20 percent; and the method of preparing this composition, including, heating the bituminous material to a temperature above its melting point and pumping the same into a blending tank equipped with cooling coils and an impeller-type mixer, immediately adding the paraffinic solvent to the bituminous material at a slow rate while agitating and cooling, thereafter adding the naphthenic solvent to the mixture when the temperature of the mixture reaches a point above 25* F. below the boiling point of the naphthenic solvent, agitating and cooling the mixture until the mixture reaches a temperature between about 100 and 105* F., and slowly adding the methylene chloride, while continuing cooling to essentially ambient temperature over an extended period of time, such as 30 minutes.
