EVALUATION OF A FLEXIBLE PAVEMENT IN ILLINOIS

THE PERFORMANCE OF A BITUMINOUS-CONCRETE SURFACED AGGREGATE-BASE PAVEMENT BUILT IN 1952-53 WAS OBSERVED OVER A 12-YEAR PERIOD OF SERVICE TO PRIMARY HIGHWAY TRAFFIC. THE STUDY WAS DESIGNED TO PROVIDE INFORMATION ON THIS TYPE OF PAVEMENT WHEN SERVING PRIMARY HIGHWAY TRAFFIC IN ILLINOIS. THE STRUCTURAL DESIGN WAS SELECTED BY THE ORIGINAL DESIGNERS, BASED ON INFORMATION AVAILABLE TO THEM AT THE TIME (1951), AS HAVING A POTENTIAL FOR AFFORDING ABOUT THE SAME PERFORMANCE AS TYPICAL RIGID PAVEMENTS THEN BEING CONSTRUCTED IN ILLINOIS. ITS PERFORMANCE WAS NOT UP TO EXPECTATIONS. WHEN THE CURRENT ILLINOIS FLEXIBLE PAVEMENT DESIGN PROCEDURE FOR WHICH THE ASSHO ROAD TEST FINDINGS SERVED AS A BASIS WAS DEVELOPED, THE RESULTS OF THE STUDY WERE USED TO PROVIDE MODIFICATION THAT WOULD ACCOUNT FOR THE DIFFERENCES BETWEEN SERVICE AND EXPOSURE CONDITIONS AT THE ROAD TEST AND THOSE EXISTING IN THE MORE NORMAL SITUATION. /AUTHOR/
