• Abstract:
  California Bearing Ratio (CBR) of subgrade soils, which can be used in design of flexible pavements, can be obtained from Dynamic Cone Penetrometer (DCP) tests through a statistical correlation. The main objective of this study was to determine an acceptable CBR value based on the use of statistical pavement performance evaluation models. To this end, actual DCP tests, along with the thickness of unbound layer and traffic data in the form of Average Annual Daily Truck Traffic (AADTT) were used as predictors for statistical analyses conducted in this study. Distress indicators of in-service pavements including total rutting, fatigue cracking, transverse cracking, roughness, and quality of pavement cores were the outcomes of the analyses.
