THE ASSESSMENT AND IMPROVEMENT OF PAVING BITUMEN PERFORMANCE

A REVIEW IS CONDUCTED OF PRESENT KNOWLEDGE ON THE PERFORMANCE OF BITUMENS IN ROAD AND AIRFIELD PAVEMENTS AND THE ASSEMENT OF THIS PERFORMANCE IS MADE WITH SPECIAL REFERENCE TO AUSTRALIAN CONDITIONS. BASIC ASSESSMENT OF PERFORMANCE AWAITS THE DEVELOPMENT OF A SIMPLE RELIABLE 'MICRO' METHOD FOR MEASURING THE VISCO-ELASTIC PARAMETERS OF THE MATERIAL AT 50 CYCLES/SEC. AND AT THE EXTREMES OF PAVEMENT TEMPERATURE--10 C. AND 60 C. THE PRIMARY CAUSE OF DETERIORATION OF THE MATERIAL IN SERVICE APPEARS TO BE SLOW ATTACK BY ATMOSPHERIC OXYGEN BOTH IN THE PRESENCE AND ABSENCE OF LIGHT. POSSIBLE WAYS OF IMPROVING RESISTANCE TO OXIDATION BY MODIFIED PROCESSING OR BY THE ADDITION OF 'ANTI -OXIDANTS' ARE CONSIDERED. /AUTHOR/
