A SOIL ASPHALT STABILIZATION REPORT

THE LACK OR GRADUAL DEPLETION OF AGGREGATE SOURCES WITHIN ECONOMICAL DISTANCE OF MANY HIGHWAY CONSTRUCTION PROJECTS HAS RESULTED IN AN INCREASING INTEREST IN THE STABILIZATION OF FINE GRAINED SOILS. SANDY SOILS ARE FAIRLY COMMON IN THIS PROVINCE AND DEPOSITS CAN GENERALLY BE FOUND IN CLOSE PROXIMITY TO OUR HIGHWAY PROJECTS. THIS HAS MADE POSSIBLE THEIR ECONOMIC USE AS A BASE COURSE MATERIAL AND SANDS HAVE BEEN UTILIZED IN MANY INSTANCES SINCE 1959, USING PORTLAND CEMENT AS A STABILIZING ADDITIVE. THE PAST FEW YEARS HAVE SEEN INCREASED ACTIVITY INTO THE DEVELOPMENT OF METHODS OF ASPHALT STABILIZATION OF FINE GRAINED MATERIALS. OTHER PROVINCES, NOTABLY MANITOBA, AND SEVERAL U.S. STATES HAVE HAD SUCCESS USING THESE MATERIALS IN SUB-BASE CONSTRUCTION. IN THIS CONNECTION A SECTION OF BASE COURSE, EMPLOYING AN ASPHALT-STABILIZED SAND SUB-BASE, WAS PLACED BY THE DEPARTMENT OF HIGHWAYS DURING THE PAST SEASON /1963/. THE PURPOSE OF PLACING THIS ASPHALT BASE WERE TWO-FOLD, BEING' 1/ TO EVALUATE ASPHALT STABILIZATION OF SOME OF OUR TYPICAL SAND TYPES UNDER ALBERTA CLIMATIC AND ENVIRONMENTAL CONDITIONS, AND 2/ TO DEVELOP A SUCCESSFUL ALTERNATE TO SOIL-CEMENT FOR THE OBVIOUS ECONOMIC REASONS. /NAPA/
