The authors present the results and analysis of amplitude sweep tests done on 10 different asphalt binders using dynamic shear rheometer. The test was done from 30 to 70°C using a spindle geometry of 25 mm diameter with 1 mm gap setting. Matching function concept coupled with a three stage optimization procedure has been used to propose a new model for evaluating the complex modulus of bitumen at any given temperature and strain level. The model has been validated and is found to be fairly accurate for different types of binders. © 2016 Taylor & Francis Group, LLC.
