ASTM RR:D04-1041 PDF Download

ASTM RR:D04-1041 is a standard that outlines a procedure for extracting asphalt binder from asphalt mixtures using an automated system. The purpose of this test method is to determine the amount of asphalt binder present in the asphalt mixture, which is crucial for evaluating its quality and performance.

The standard describes the equipment and materials required for the extraction process, including an extraction apparatus, solvent, and filter papers. The asphalt mixture is first prepared by breaking it down into smaller particles and ensuring that it is thoroughly mixed. Then, a sample of the mixture is weighed and placed in the extraction apparatus.

The apparatus is operated following specific parameters outlined in the standard, such as the extraction temperature, extraction time, and the type of solvent used. The automated system performs the extraction process, which involves dissolving the asphalt binder from the mixture and filtering out any solid particles. After the extraction is complete, the binder solution is collected, and the solvent is evaporated.

The amount of asphalt binder extracted is determined by weighing the residue remaining in the extraction apparatus and comparing it to the weight of the initial sample. This provides a quantitative measure of the asphalt binder content in the asphalt mixture.
