THE EFFECT OF SKIP-GRADING ON STABILITY OF SOIL-AGGREGATE MIXTURES

THE EFFECT OF VARYING THE AMOUNT OF MATERIAL RETAINED BETWEEN THE NO. 30 AND NO. 200 SIEVES ON THE STABILITY OF SOIL-AGGREGATE MIXTURES WAS EVALUATED. ONLY THOSE MATERIALS THAT CONFORM ESSENTIALLY TO INDIANA SPECIFICATION NO. 53 AGGREGATE WERE USED. ATTERBERG LIMITS, COMPACTION, CBR, TEXAS TRIAXIAL COMPRESSION, AND PERMEABILITY TESTS WERE PERFORMED, AND TEST DATA WERE STATISTICALLY ANALYZED USING ANALYSIS OF VARIANCE TECHNIQUES. IT WAS FOUND THAT THE VARIATION OF MATERIAL BETWEEN THE TWO SIEVES HAD AN IMPORTANT BEARING ON THE STABILITY OF THE SOIL-AGGREGATE MIXTURES. THIS EFFECT, HOWEVER, WAS INFLUENCED BY THE QUANTITY OF FINES PRESENT IN THE MIXTURES AND THE PLASTICITY CHARACTERISTICS OF THE FINES. THE CONCLUSIONS SUGGEST LIMITING VALUES OF DUST RATIO AND PERCENT PASSING THE NO. 30 MESH SIEVE FOR THE SOIL-AGGREGATE MIXTURES WITH LOW PLASTICITY FINES AND COMPACTED TO STANDARD AASHO DENSITY.
