Design parameters are input into the program including the length of the analysis period, serviceability index, and design confidence level.
This information often includes: traffic loads, serviceability index, reliability, material characterization, drainage characteristics, and evaluating existing pavement conditions.
The Present Serviceability Index (PSI) is used to set up performance levels over the period of analysis.
Present Serviceability Index: Both of the accepted TxDOT pavement design procedures use the Present Serviceability Index concept for quantifying pavement performance.
Flexible pavement designs were obtained for four traffic levels and two serviceability index ranges (4.0 to 2.0, and 4.5 to 2.5).
