Abstract

Aging of asphalt has implications during the construction of pavements and their long-term performance. The asphalt binder is known to stiffen during the mixing and lay down operations as well as during the service life of the pavement. Laboratory aging procedures have been set up to simulate the aging process in the field through the use of accelerated tests. Rheological characterization of the aged asphalts is carried out to get a measure of the extent of stiffening due to aging. However, the laboratory aging procedures along with the rheological characterization ...
