Imaging Studies on Aggregates and Asphalt Mix--from Micorscope to Camera

Event Date/Time: 
July 10, 2018 - 10:00am
Event Location: 
3546D Engineering Building
Speaker: 
Animesh Das, Ph.D., Professor, Department of Civil Engineering, Indian Institute of Technology
Civil Engineering Seminar

Abstract

The size of aggregates used in asphalt mix varies from a few microns to a few centimeters. Thus, different imaging equipment are necessary to capture information at different scales. In this talk, Dr. Das will discuss recent explorations with scanning electron microscope, optical microscope, desktop scanner, and camera on aggregates and asphalt mix . Some ideas and results related to shape characterization of aggregates, asphalt binder adsorption in aggregates, estimation of aggregate size distribution, nature and effect of aggregate distribution (ranging from coarse aggregate to filler) on the response of asphalt mix etc. will be presented.
