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.
