Details
Traditional asphalt mix designs are being done using volumetric approach in many countries of the world. Even though the original Superpave mix design system had the performance testing requirements, it was limited to only performance graded binders testing and only specialty projects for asphalt mixtures. Most agencies in the US have revised Superpave mix designs and binder requirements to make quality asphalt mixtures. However, the dependence of Superpave mix design on volumetric requirements for durability has poor precision in terms of VMA and its direct relationship of aggregate specific gravity. The new balanced mix design concept of optimizing binder content based on rutting and cracking performance can be done in using several performance testing methods. Maryland has chosen to use surrogate testing methods for its simplicity, quick turnaround, and high reliability.

Presenter
Chandra K. Akisetty, PhD., PE
Dr. Akisetty is Asphalt Technology Division Chief at Maryland State Highway and is one of the technical experts on this project. He specializes in the design and testing of various asphalt binders and mixtures using Superpave methods. Dr. Akisetty has obtained his MS Degree from IIT Roorkee in India, and Ph.D. in Civil Engineering from Clemson University, SC., with a focus on asphalt technology. He is a registered professional engineer in Maryland and has 15 years of work experience in in design, construction, and statistical analysis of hot, warm, and cold asphalt mixtures. He was a member of carbon emission credits development methodology for using cold recycled mixtures using foamed asphalt and asphalt emulsions.
