2020 - Australia - Relationship Between Objective and Subjective Pavement Distress Measurements

An interesting study which develops a set of relationships between subjective pavement Surface Inspection Rating (SIR) and automated pavement distresses, with an investigation of interactions between pavement distresses. The pavement condition parameters/distresses include cracking, rutting, texture loss and roughness. In addition, the influences of pavement operating conditions (such as age and heavy vehicle traffic volume) on the measured strength of relationships between subjective rating and objective pavement distresses, are studied.
