Recently, a nanoindentation test<br>can characterize an asphalt binder film in the form of a coating around roadway aggregates, which is more practical.<br>In a nanoindentation test, a sharp tip is used to indent an asphalt film while residing on an aggregate surface to<br>determine nanoindentation modulus (E). This study evaluates whether there is a relation between G* and E. For<br>both tests, replicate samples were conditioned in three ways: unaged, rolling thin film oven aged, and pressure<br>vessel aging. Results show that the E-value is approximately 2 to 6 times larger than the G*-value based on all<br>samples/conditioning.<br><br></p>}, number={35}, journal={GEOMATE Journal}, author={Hasan M.
