Asphalt composition containing a liquid hydrogenated polymer oil

Claim 1

A COMPOSITION OF MATTER CONSISTING ESSENTIALLY OF ASPHALT AND 0.5 TO 15% OF A HYDROGENATED LIQUID POLYMER OIL HAVING AN IODINE NUMBER BELOW 150 AND PREPARED BY MIXING 50 TO 100 PARTS BY WEIGHT OF BUTADIENE-1,3 WITH 50 TO 0 PARTS BY WEIGHT OF STYRENE, 50 TO 500 PARTS BY WEIGHT OF AN INERT HYDROCARBON DILUENT BOILING BETWEEN ABOUT 20 AND 200*C., 1 TO 100 PARTS OF AN ETHER SELECTED FROM THE GROUP CONSISTING OF C4-C8 ALIPHATIC ETHERS AND CYCLIC ETHERS HAVING THE OXYGEN ATOMS SEPARATED BY 2 CARBON ATOMS, 1.2 TO 8 PARTS OF FINELY DISPERSED SODIUM AND 10 TO 50% BY WEIGHT OF C3-C5 ALCOHOL BASED ON THE WEIGHT OF SODIUM, HEATING THE MIXTURE TO A REACTION TEMPERATURE BETWEEN 25 AND 105*C. UNTIL SUBSTANTIALLY 100% CONVERSION IS OBTAINED, DESTROYING AND REMOVING THE CATALYST AND SUBSEQUENTLY CONTACTING THE RESULTING POLYMER WITH HYDROGEN UNDER THE PRESSURE OF ABOUT 100 TO 5000 P.S.I.G. AT A TEMPERATURE BETWEEN ABOUT 200 AND 500*F. THE PRESSURE OF A HYDROGENATION CATALYST.
