APPLICATION OF AASHO ROAD TEST EQUATIONS TO MIXED TRAFFIC

THE GENERAL PAVEMENT PERFORMANCE EQUATIONS DEVELOPED AT THE AASHO ROAD TEST DESCRIBE THE BEHAVIOR OF PAVEMENTS WHEN SUBJECTED TO REPEATED APPLICATIONS OF AN AXLE LOAD OF A GIVEN TYPE AND WEIGHT. TO APPLY THE EQUATIONS TO THE PROBLEMS OF HIGHWAY DESIGN IT IS NECESSARY TO TRANSFORM THE SINGLE-LOAD EQUATIONS TO MULTILOAD FORM. THE "MIXED TRAFFIC THEORY" PRODUCES A MULTILOAD EQUATION IN THE FORM OF AN INTEGRAL THAT CAN NOT BE READILY EVALUATED, BUT THE "EQUIVALENT APPLICATIONS APPROACH" YIELDS A MANAGEABLE EQUATION THAT APPROXIMATES THE RESULTS OBTAINED BY MECHANICAL INTEGRATION OF THE EQUATION DERIVED BY THE MIXED TRAFFIC THEORY. THE DIFFERENCE IN THE RESULTS OBTAINED BY THE TWO METHODS IS NEGLIGIBLE FOR ALL EXCEPT RELATIVELY THIN FLEXIBLE PAVEMENTS. /AUTHOR/
