AASHTO T 317 – Standard Method of Test for Prediction of Asphalt-Bound Pavement Layer Temperatures

This test method provides a standard for measuring pavement surface temperature and predicting temperatures within the asphalt-bound layer(s) of a flexible pavement section. This test method provides a means of estimating the temperature at-depth from the pavement surface temperature, the time of day, the previous day’s high- and low-air temperatures, and the desired depth where the temperature is to be estimated.

Deflection testing commonly involves the measurement of the pavement surface termperatures. This standard is based on temperature relationships developed as part of the Federal Highway Administration (FHWA) Long-Term Pavement Performance (LTPP) Seasonal Monitoring Program.
