AASHTO M 82-17 (2021) is a standard specification that pertains to cutback asphalt, specifically the medium-curing type. Cutback asphalt refers to a liquid petroleum product that is produced by mixing an asphaltic base with appropriate petroleum distillates. This specific type of cutback asphalt is primarily used for treating road surfaces.

The purpose of this standard is to establish the requirements and test methods for medium-curing cutback asphalt, ensuring its suitability and performance in road surface treatments. It serves as a guide for manufacturers, suppliers, and contractors involved in the production, distribution, and application of cutback asphalt for road construction and maintenance projects.

In order to meet the specifications of AASHTO M 82-17, the medium-curing cutback asphalt must adhere to certain characteristics and properties. These include specific gravity, viscosity, flash point, distillation range, solubility, and residue content. The standard outlines the methods for conducting tests to determine the compliance of the cutback asphalt with these requirements.
