Complex Stiffness Gradient Estimation of Field-Aged Asphalt Concrete Layers Using the Direct Tension Test
Publisher: American Society of Civil Engineers
Abstract: The characterization of viscoelastic properties of the aged field asphalt mixtures has been a challenge for pavement engineers. Instead of characterizing full mixtures from the field cores, only the binder was extracted ...
New Methodology to Find the Healing and Fracture Properties of Asphalt Mixes Using Overlay Tester
Publisher: American Society of Civil Engineers
Abstract: Asphalt layers under different repeated loading and rest periods experience both fatigue and healing processes. The tests are costly and time consuming and the results are highly variable. Current methods of evaluating ...
