SEASONAL VARIATIONS IN FLEXIBLE PAVEMENT STRENGTH

GENERAL RELATIONSHIPS BETWEEN THE STRENGTH OF FLEXIBLE PAVEMENTS AND SEASON ARE PRESENTED. A DETAILED EXAMINATION OF THE PHYSICAL AND ENVIRONMENTAL CHARACTERISTICS OF SELECTED PAVEMENT INVENTORY SECTIONS IN ALBERTA REVEALS THE ABSENCE OF AN EXPLICIT EXPRESSION FOR THE OBSERVED VARIATION OF STRENGTH BETWEEN SPRING AND FALL. THE SIGNIFICANCE OF THE SPRING TO FALL DEFLECTION RATIO IS DISCUSSED. THE APPLICABILITY OF SPRING AXLE-LOAD RESTRICTIONS IS VALIDATED BY COMPARISON OF ACTUAL PAVEMENT PERFORMANCE LOSSES TO THOSE PREDICTED BY MATHEMATICAL RELATIONSHIPS DEVELOPED FOR CANADIAN CONDITIONS. A HYPOTHESIS REGARDING DIFFERING ELASTIC CHARACTERISTICS OF FLEXIBLE PAVEMENTS BETWEEN SPRING AND FALL IS SUGGESTED. /CGRA/RRL/
