RETARDING THE AGEING OF THE BITUMEN BY MEANS OF AGEING INHIBITORS /IN GERMAN/

AFTER OUTLINING THE PHYSICAL AND CHEMICAL CAUSES OF BITUMEN AGEING, OF WHICH THE MOST IMPORTANT IS OXIDATION, THE AUTHOR PRESENTS TEST RESULTS IN WHICH 34 DIFFERENT INHIBITORS, BOTH ORGANIC AND INORGANIC, WERE ASSEDDED. DEGREE OF AGEING WAS DETERMINED BY MEANS OF VISCOSITY MEASUREMENTS AND INFRARED SPECTROSCOPY. AGEING CAN BE RETARDED BUT NOT COMPLETELY PREVENTED. THE EFFICIENCIES OF THE THIRTEEN MOST ACTIVE ADDITIVES WITH RESPECT TO HARDENING AND OXIDATION RATE, BOTH IN THE DARK AND IN LIGHT, ARE COMPARED IN A CHART. /AUTHOR/
