National Road Research Alliance Publishes Report Written With Advisement of SRF’s Expertise

Did you know that in addition to preservation treatment and new construction, diamond grinding has more recently been used for noise reduction?

With the help and advisement of SRF’s Joe Korzilius and Renae Keuhl, National Road Research Alliance recently published a report that provides a synthesis of the best diamond grinding practices used by NRRA member states, including California DOT, Illinois DOT, Iowa DOT, Michigan DOT, Minnesota DOT, Missouri DOT, North Dakota DOT, and Wisconsin DOT. The report explores when diamond grinding is best applied, improvement at the time of construction and how long improvements last, and potential vulnerabilities of diamond grinding.
