AASHTO T 319-15 (2019) PDF Download

The AASHTO T 319-15 (2019) standard provides a standardized method for the quantitative extraction and recovery of asphalt binder from asphalt mixtures. This method ensures that the physical and chemical properties of the asphalt binder recovered are minimally affected during the process. The standard is suitable for use when determining the physical or chemical properties of the recovered asphalt binder, as well as for quantifying the quantity of asphalt binder in the hot-mix asphalt (HMA) or reclaimed asphalt pavement (RAP). Additionally, the recovered aggregate can be utilized for sieve analysis. The standard can be applied to samples obtained from various sources, including the pavement, stockpile, HMA plant production, or laboratory fabricated HMA.
