RHEOLOGICAL PROPERTIES OF COMPACTED SOIL-ASPHALT MIXTURES

A STUDY WAS MADE OF THE STRENGTH CHARACTERISTICS OF SOIL- ASPHALT MIXTURES FOR CERTAIN PARTICULAR TYPES OF STRESS CONDITIONS. THE STRESS SYSTEM CONSIDERED WAS THAT OF A STEADY-LOAD TYPE FOR WHICH A CONSTANT OF UNCONFINED COMPRESSIVE NATURE WAS APPLIED ON A CYLINDRICAL SPECIMEN AND THE DEFORMATION OF THE SPECIMEN WAS OBSERVED AS A FUNCTION OF TIME. OTHER TESTS WERE CARRIED OUT AT CONSTANT RATES OF AXIAL STRAINS WITH INCREASING STRESS. ONLY ONE SOIL TYPE OF ASPHALT, A MEDIUM-CURING LIQUID TYPE, WERE USED IN THIS INVESTIGATION. UNDER CONSTANT RATES OF STRAIN AND WITH INCREASING STRESS, NO APPRECIABLE INCREASE IN THE MAXIMUM STRENGTH WAS INDICATED BY INCREASING THE RATE OF DEFORMATION THE PERCENTAGE INCREASE IN THE MAXIMUM STRENGTH WITH LOADING SPEEDS WAS GREATER FOR THESE MIXTURES WITH LARGE PERCENTAGES OF ASPHALT. THE RELATIONSHIP BETWEEN THE STRESS AND LOG TIME AT FAILURE WAS LINEAR. THE STRESS LEVEL AND CURING TIME AFTER COMPACTION WERE THE MOST IMPORTANT FACTORS AFFECTING THE RHEOLOGICAL PROPERTIES OF THE MATERIAL.
