  1. Old Action Items:

A.NCHRP Synthesis Proposals

“QC/QA State of the Practice” – Gerry Huber

B. TRB Circulars and TR News Articles

The committee had previously recommended writing a TR News article on Warm Mix Asphalt. Dave Newcomb said that Matt Corrigan had written an article on this that would be appropriate to publish as a TR News article, if it had not been previously published. Newcomb will follow-up on this.

According to Don Watson, Doug Hanson had agreed to write a TR News article on noise for the committee. A primer on what is happening would be appropriate. Decker said that he had already written something on this for NAPA but it had not yet been published. It may be possible to use that instead. Decker and Newcomb will look into this.

C.Research Needs Statements (RNS forms are available at TRB website):

Lab Compaction Method to Establish Target Density Requirements for HMA Construction – Terry Burger/Joe Button

Low-Cost, High-Quality HMA – Don Brock and Ron Collins

Mix Design for Asphalt Overlays – Don Brock and Ron Collins

Avoiding Moisture-Susceptible Asphalt Mixtures – Barry Takallou/Joe Button

D.Barry Takallou will organize a session on International Uses of Asphalt Rubber with suggestions from Frank Fee.

Dave Newcomb will determine whether NAPA has published an article on Warm Mix Asphalt written by Matt Corrigan. If not, he will forward to Fred Hejl by July 1, with a copy to Joe Button, for possible publication in TR News.

  1. Develop/Finalize Plans for Future Committee Activities
