AASHTO M 226-80 (2017) PDF Download

AASHTO M 226-80 (2017) is a standard specification that specifically addresses the characteristics and usage of viscosity-graded asphalt cement in the construction of pavement. This specification focuses on asphalt binders and provides guidelines for grading them based on viscosity at a specified temperature of 60°C (140°F).

The standard offers three different sets of limits for grading the asphalt binders, with the specific choice to be made by the purchaser. It is important for the purchaser to specify the appropriate table of limits to ensure that the asphalt binder meets the desired viscosity requirements for the intended pavement construction project.

By outlining the grading criteria for viscosity, AASHTO M 226-80 (2017) provides a standardized approach for selecting and using asphalt cement with the desired viscosity properties, which is crucial for ensuring the durability and performance of the pavement.
