ASTM D7228-06

ASTM D7228-06 - 1.5.2006

1. Scope

1.1 This test method covers a means of predicting temperatures within the asphalt-bound layer(s) of a flexible pavement section.

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