Accelerated Life Testing Model Development

I have Hamburg Wheel Tracking Device Testing data for testing Life of asphalt mix (pavement).

The failure criteria are 20mm rut depth or 20,000 wheel passes in laboratory. Some data are censored as it reach 20,000 wheel passes before reaching 20 mm rut depth. What SAS procedure or code can be used for the development of accelerated modeling?

The data are in two temperature levels (50 deg C and 60 deg C) and two load (stress) levels (158lbs and 168lbs loads). The nature of degradation curve is non linear. I need a model in high stress level which can predict the normal loading condition. Message was edited by: Chandra2
