Asphalt Lubricity Test

This newly developed test is designed for the Dynamic Shear Rheometer. It is based on the concept that in addition to viscosity, the reduction in internal friction of the asphalt binder contributes to asphalt mixture workability.

This test is being evaluated as a measure of asphalt binder workability and a mixture workability evaluation criteria.

Binder Bond Strength (BBS)

The Binder Bond Strength test (BBS) has been proposed by MARC as a practical method to measure bond strength between aggregate and asphalt binder.

Recently approved as AASHTO Standard TP 91.

BBR-SENB

The BBR-SENB system is a modification of the Bending Beam Rheometer, that enables low temperature fracture testing on BBR size beams.

MARC continues to evaluate the potential of the BBR-SENB system for better estimation of the thermal cracking susceptibility of asphalt materials.

MARC Researcher Awarded "Dr. David R. Jones IV" Scholarship by AMAP

MARC researcher, Raquel Moraes, was awarded the 2014 "Dr. David R. Jones IV" Scholarship by the Association of Modified Asphalt Prodcuers (AMAP). Raquel has worked on a number of research projects concering the forumation and performance of modified asphalt binders. Her Ph.D. research is focused on the physical and chemical interaction between mineral aggregate fillers and asphalt during the oxidative aging process. The Association of Modified Asphalt Producers is dedicated to the "development, production, and use of modified asphalts for highway paving". Further information about AMAP and the scholarship is available at the official scolarship's website.

Solicitation for Transportation Pooled Fund Project on Modified Asphalt Specifications

WisDOT and the Modified Asphalt Research Center at University of Wisconsin - Madison, are partnering to from a pooled fund studying binder specification test methods. Participation in this pooled fund presents an opportunity for specifying agencies and users to support research on development of specifications and acceptance criteria for modified binders with a focus on test methods that are most related to performance and meet specific needs. The product of this research will be a unified modified binder specification developed in cooperation with partner states and User-Producer Groups delivered in a format that will allow for rapid implementation and deployment. For more information on the project and how to join, please visit the FHWA approved solicitation posted on the Transportation Pooled Fund website.
