STUDIES OF NATURALLY OCCURING SANDS AND GRAVELLY SANDS WITH REGARD TO THEIR USE FOR MANUFACTURING HOT-MIXED BITUMINOUS ROADBASES. PART 2

THE TESTS WERE INTENDED TO CLARIFY THE RELATIONS BETWEEN THE TEMPERATURE AND STABILITY OF HOT BITUMINOUS ROADBASE MIXTURES. IT WAS FOUND THAT THERE IS NO GENERALLY VALID QUANTITATIVE RELATION BETWEEN MARSHALL STABILITY AND TEMPERATURE. THE TESTS, WHICH WERE CARRIED OUT ON THE ROUNDED GRAVEL MIXTURES WITH TWO DIFFERENT BITUMENS AND VERY DIFFERENT STABILITITES AT 60 DEGREES C, DID NOT CONFIRM THE LINEAR DEPENDENCE OF THE LOGARITHM OF STABILITY ON TEMPERATURE AS DETERMINED BY PIGNATARO. IT IS SUGGESTED THAT THE MEASUREMENT OF THE STABILITY OF HOT-MIXED BITUMINOUS ROADBASES AT 60 DEGREES C BE REPLACED BY TESTING AT 40 DEGREES C, AS THIS TEMPERATURE IS CRITICAL FOR STABILITY. /TRRL/
