Development of Criteria for Durability of Modified Asphalt

摘要

The main objectives of the research are as follows: To study the effect of a fewselected modifiers to the temperature susceptibility and flow properties of typical paving asphalts used in Florida; To determine the optimum modifier contents of these selected modifiers for typical paving mixtures used in Florida; To study the aging characteristics of these selected modified asphalts; and To develop and evaluate the test methods and criteira for selection of modified asphalts to be used in paving mixtures.
