Abstract
Description
This Technical Brief provides an overview of the binder parameter Delta Tc (�"Tc). Delta Tc is an indicator of the effect of aging and additives on the asphalt rheology. More specifically, �"Tc provides insight into the relaxation properties of an asphalt binder that can contribute to non-load related cracking or other age-related embrittlement distresses in an asphalt pavement. This Technical Brief provides information for responsible deployment of the �"Tc as a specification parameter should State DOTs be considering implementation.
