Publication Details

LTPP Pavement Performance Forecast Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Surface and Other Considerations

Description: Developed as part of pooled fund study TPF–5(013), the Long–Term Pavement Performance (LTPP) Performance Forecast produces freeze/thaw performance predictions for both rigid and flexible pavements. These predictions are based on regression models using data available from approximately 800 in–service test sections in the LTPP database. These sections consist of a variety of climates with various subgrade types and a range of loading conditions. Using the LTPP Performance Forecast, researchers can compute roughness, structural cracking, environmental cracking, rutting, and faulting predictions as a function of pavement age. The forecasts are based on user–defined inputs for traffic, structure, environment, and subgrade conditions.
