About Task Group 2

UW–Madison coordinates Task Group 2 of RILEM Technical Committee 206-ATB on advanced testing and characterization of bituminous materials. The objective of TG2 is to develop tools other than density to identify mixture microstructure. The current project involves the analysis of specimens created from the same mixture but with different compaction methods. This Web page will be used to relay important project developments and provide a common area to share ideas.

TG2 includes a multinational team of participants.
