Method of preparing finely-divided asphaltic material

Claim 1

A METHOD FOR PREPARING AN ASPHALTIC POWDER FROM ASPHALTIC RESIDUUM, SAID BEING A A SOLID AT ROOM TEMPERATURE, CONSISTING ESSENTIALLY OF HEATING SAID ASPHALTIC RESIDUUM TO A TEMPERTURE BETWEEN ABOUT 100 AND 200* F. ABOVE THE SOFTENING POINT OF SAID RESIDUUM, INTRODUCING THE RESULTANT MOLTEN ASPHALTIC RESIDUUM INTO A POOL OF AN ANTI-COALESCING LIQUID MAINTAINED AT A TEMPERATURE AT LEAST 75*F. BELOW THAT OF SAID SOFTENING POINT WHILE AGITATING SAID LIQUID SUFFICIENTLY TO CAUSE A VIOLENT AND IRREGULAR MOVEMENT THEREOF, SAID ANTI-COALSCING LIQUID SELECTED FROM THE GROUP CONSISTING OF WATER AND 25 TO 60 VOL. PERCENT AQUEOUS GLYCAL, AQUEOUS GLYCEROL, AQUEOUS ALKANOL AND AQUEOUS ALKANONE OF 1 TO 4 CARBONS, AND SAID ANTI-COALECING LIQUID BEING PRESENT IN VOLUMETRIC EXCESS IN RESPECT TO SAID RESIDUUM, WHEREBY SAID ASPHALTIC POWDER SEPARATES FROM THE FINAL LIQUID PHASE AND RECOVERING SAID POWDER.

Claim 2

A METHOD FOR PREPARING AN ASPHALTIC POWDER FROM ASPHALTIC RESIDUUM, SAID BEING A A SOLID AT ROOM TEMPERATURE, CONSISTING ESSENTIALLY OF HEATING SAID ASPHALTIC RESIDUUM TO A TEMPERTURE BETWEEN ABOUT 100 AND 200* F. ABOVE THE SOFTENING POINT OF SAID RESIDUUM, INTRODUCING THE RESULTANT MOLTEN ASPHALTIC RESIDUUM INTO A POOL OF AN ANTI-COALESCING LIQUID MAINTAINED AT A TEMPERATURE AT LEAST 75*F. BELOW THAT OF SAID SOFTENING POINT WHILE AGITATING SAID LIQUID SUFFICIENTLY TO CAUSE A VIOLENT AND IRREGULAR MOVEMENT THEREOF, SAID ANTI-COALSCING LIQUID SELECTED FROM THE GROUP CONSISTING OF WATER AND 25 TO 60 VOL. PERCENT AQUEOUS GLYCAL, AQUEOUS GLYCEROL, AQUEOUS ALKANOL AND AQUEOUS ALKANONE OF 1 TO 4 CARBONS, AND SAID ANTI-COALECING LIQUID BEING PRESENT IN VOLUMETRIC EXCESS IN RESPECT TO SAID RESIDUUM, WHEREBY SAID ASPHALTIC POWDER SEPARATES FROM THE FINAL LIQUID PHASE AND RECOVERING SAID POWDER.
