AN INVESTIGATION OF THE STRENGTH PROPERTIES OF SAND EMULSIFIED ASPHALT MIXTURES

AN EXAMINATION IS DESCRIBED OF THE GRADING AND STRENGTH CHARACTERESTICS OF UNTREATED ONTARIO SANDS AND THE STABILITY AND STRENGTH CHARACTERISTICS OF THESE SANDS TREATED WITH VARYING AMOUNTS OF EMULSIFIED ASPHALT. TENTATIVE RELATIONSHIPS WERE ESTABLISHED AMONG THE GRADING CHARACTERISTICS OF THE UNTREATED SANDS, THE STRENGTH CHARACTERISTICS OF FRICTION, COHESION AND UNCONFINED COMPRESSION STRENGTH OF THE SAND-EMULSION MIXES AND THE EMPIRICAL TEST RESULTS. A METHOD OF PREDICTING THE SUITABILITY OF SANDS, WHEN MIXED WITH EMULSIFIED ASPHALT, FOR USE AS HIGHWAY BASE OR SUBBASE MATERIAL, USING ONLY THE RESULTS OF A COMPLETE SEIVE ANALYSIS, IN CONJUNCTION WITH THESE RELATIONSHIPS IS SUGGESTED. AN ABBREVIATED SERIES OF TESTS WERE PERFORMED ON TWO ADDITIONAL SANDS IN AN ATTEMPT TO PROVIDE CONFIRMATION OF THIS METHOD. THE WATER CONTROL TEST INDICATED THAT WATER CONTENT AT TIME OF TEST HAS AN EFFECT ON THE STRENGTH OF SAND-EMULSION MIXES. THIS HAS BEEN CONFIRMED BY FURTHER WORK AT QUEENS UNIVERSITY WHERE IT HAS BEEN SHOWN THAT TESTING MOISTURE CONTENT AND MIXING AND COMPACTING MOISTURE CONTENT BOTH HAVE AN EFFECT ON THE STRENGTH OF THE MIX. /CGRA/
