ASTM D6521-13,Standard Practice for Accelerated Aging of Asphalt Binder Using a Pressurized Aging Vessel (PAV).
A net friend from Canada sent me this standard. Thank her very much.Let’s take a look at some of the introduction of this standard.
ASTM D6521-13 covers the accelerated aging (oxidation) of asphalt binders by means of pressurized air and elevated temperature. This is intended to simulate the changes in rheology which occur in asphalt binders during in-service oxidative aging but may not accurately simulate the relative rates of aging.
This practice is designed to simulate the in-service oxidative aging that occurs in asphalt binders during pavement service. Residue from this conditioning practice may be used to estimate the physical or chemical properties of asphalt bindersafter several years of in-service aging in the field.
Is this standard helpful to you? Welcome to leave a message to me below. I will reply as soon as possible.
