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.
Bitumen Bond Strength (BBS)
The Bitumen Bond Strength test (BBS) has been proposed by MARC as a practical method to measure cohesion of binders and adhesion between aggregate and asphalt binder.
Draft AASHTO standard is currently under review.
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.

Second International Workshop on Asphalt Mastics
April 18, 2012 – The second International Workshop on Asphalt Mastics, organized by UW-Madison TU Delft, and KTH (Royal Institute of Technology), will be held on June 18, 2012 at TU Delft, Netherlands. The main objective of this workshop is to serve as a platform for exchange of information on the state-of-art in various aspects of modeling and characterization of asphalt mastics.

MARC trains ETG members in use of the Linear Amplitude Sweep test
Feb 22, 2011 – MARC held a webinar on Feb 22 in which Ms. Cassie Hintz and Dr. Raul Velasquez explained the conduction and analysis of the newly introduced Linear Amplitude Sweep (LAS) binder fatigue test. Participants were shown videos of the LAS procedure implementation into commonly used Dynamic Shear Rheometers (DSR). The session also included a demonstrated of the use of the LAS analysis spreadsheet and data interpretation. The meeting was ended with a question and answer session held by Dr. Velasquez on the test theory and procedure.
