Abstract

All noncomplying penetration and absolute viscosity results must be verified before being reported. This verification of test results is done by reheating and retesting the identical sample that is suspect. The District Laboratories are required to submit penetration and absolute viscosity correlation samples to the Central Laboratory. These samples are the identical ones tested by the District Laboratories. When the Central laboratory tests these correlation samples they are also considered to be reheated and retested. Reheating a sample will harden the asphalt to some degree and possibly cause a change in the test results. This investigation was conducted to determine how much change in penetration and absolute viscosity could be expected by reheating and retesting asphalt samples.
