Development of a Flexible Pavement Performance Equation
During the planning for New York State's flexible pavement analysis, it was found that there was no existing equation for pavement serviceability that was satisfactory. All such equations had at least one of two deficiencies; (1) they gave too little weight to rutting, cracking, and patching, or (2) they were derived for a specified pavement roughness device, thus not suitable for the New York roughometer. Therefore, New York reverted to the procedure used at the AASHO Road Test and the Purdue University Correlation Study. That was to get ratings from a number of people for a group of pavements and correlate them with measured variables to obtain an equation. Thirty-four people were asked to rate nineteen pavements on a 0 to 5 scale. Several regression analyses were then run and equations obtained with varying mathematical forms of the measured variables. The equation representing the highest degree of correlation was then selected for us in analyzing New York State's flexible pavements. (BPR abstract)
