ANALYTICAL APPRAISAL OF THE EFFECT OF BITUMINOUS SURFACING ON THE STRESSES IN PORTLAND CEMENT CONCRETE PAVEMENT

SINCE 1941, ABOUT 3500 MILES OF THE OLDER CONCRETE PAVEMENTS IN ILLINOIS HAVE BEEN REHABILITATED BY BITUMINOUS RESURFACING, WHICH IN MOST CASES WAS PRECEDED BY WIDENING AND DESIRABLE CORRECTIONS OF ALIGNMENT. THE RESULTS OBTAINED IN THE FORM OF LOWERED MAINTENANCE COSTS AND INCREASED SERVICE LIFE WERE BEYOND EXPECTATION. THOUGH THE BITUMINOUS SURFACING IN ITSELF IS NOT CAPABLE OF WITHSTANDING BENDING STRESSES OF IMPORTANT MAGNITUDES, IT NEVERTHELESS IMPARTED INCREASED STRUCTURAL STRENGTH TO THE OLD PAVEMENTS. THE BENEFITS DERIVED ARE SUBSTANTIALLY THE CONSEQUENCE OF PROTECTIVE PROPERTIES INHERENT IN THE BITUMINOUS SURFACING. BECAUSE OF THE EXCELLENT RESULTS OBTAINED FOR OLDER PAVEMENTS, THE EXPEDIENCY OF PROTECTING CONCRETE PAVEMENTS WITH BITUMINOUS SURFACING IMMEDIATELY AFTER THEIR CONSTRUCTION IS CURRENTLY BEING STUDIED. THE FEASIBILITY OF USING CONCRETE RELATIVELY LEAN IN CEMENT TO REDUCE THE COST IS CONSIDERED. ON THE BASIS OF POSTULATED NUMERICAL QUANTITIES, MOST OF WHICH ARE SUPPORTED BY SOME INVESTIGATIONAL DATA, ATTEMPT IS MADE TO SHOW BY ANALYTICAL DEDUCTIONS THE NATURE OF SOME OF THE CONTRIBUTIONS OF BITUMINOUS SURFACING TO STRUCTURAL STRENGTH OF CONCRETE PAVEMENT, AND TO CLARIFY THE PROBLEM OF THE PRACTICABILITY OF USING MIXTURES RELATIVELY LEAN IN CEMENT FOR CONCRETE BASE CONSTRUCTION.THE VALUES DERIVED SHOULD BE CONSIDERED AS INDICATIONS OF RELATIVE QUALITIES. /AUTHOR/
