ASTM RR:D04-1008 PDF Download

The ASTM RR:D04-1008 standard provides guidelines for determining the recovery of asphalt from a solution using the Abson Method. The standard was developed based on the analysis of data from the AASHTO Materials Reference Laboratory proficiency sample database, specifically focusing on three tests: Penetration at 25°C (77°F), Kinematic Viscosity at 135°C (275°F), and Viscosity at 60°C (140°F).

The purpose of this standard is to improve the estimation of test precision for these three tests. By analyzing the proficiency sample data, the standard aims to provide users of the ASTM D1856 test method with more accurate information on test precision. This information is crucial for ensuring the reliability and consistency of test results, which are important for evaluating the quality and performance of asphalt materials.
