Ron Terrel (1936 to 2011)

We lost our good friend and partner in business and life - Ron Terrel - on March 24th, 2011.  We have developed this page on our company website to recognize some of the moments that we had with Ron over the years.

Ron's obituary was carried in the Seattle Time, on March 24, 2011 and is as follows:

"Ronald Lee Terrel, age 74, passed away peacefully surrounded by family on March 24, 2011. Born September 2, 1936, in Klamath Falls, Oregon, to Ruth and Theodore Terrel, he graduated from Illinois Valley High School and Purdue University.   Received his PhD in Civil Engineering from University of California at Berkley.  Moved to the Seattle area in 1967 where he worked as a professor of Civil Engineering at the University of Washington, where he was an Emeritus Professor since 1985. Ronald was also a faculty member of Oregon State University. He was an active member of Holy Rosary Catholic Church.

Ronald focused his professional activities on innovative research and implementation of construction materials and systems. Research projects included the use of waste products in asphalt pavements, and mixture evaluation testing and was president of the company that developed the drum mixer now used throughout the world and active in ongoing development of hot in-place recycling of asphalt pavements.

The last twenty years' focus was on the development of environmental pavement applications, including MatCon.  He was active in numerous professional associations, holds several patents, received many awards and published more than 150 technical papers and reports.

Ronald had a wonderful sense of humor and loved to start conversations with a smile and a joke. He had a genuine interest in people, enjoyed his children and grandchildren and life itself. He was exceptionally talented in woodworking and treated family members with memorable works of art.

He is preceded in death by his father, Theodore; survived by his mother Ruth, sister Judith, both of Grants Pass; wife Alice of Edmonds; three children, Douglas (Ann), Nancy (Terry), Janel (Gary); seven step-children, Tim (Bonnie), Dan, Debra (deceased), Robert (Barbara), Laura, Douglas, (Tina), Martin; twenty grandchildren, and one great-grandchild.

A memorial mass will be held at Holy Rosary Catholic Church, 7W Aloha Street in Edmonds on Monday, March 28th, 2011 at 10:00a.m. In lieu of flowers, please make donations to St. Martin de Porres Shelter in Seattle."

Our Life with Ron

Working with Ron over many years we say Ron in many roles, we have and will provide some links to the contributions that he made to us personally and those he made to the company.  This page can never recognize his complete contributions - but is is a token of our fond memories of our time with a good friend.

This was Ron's favorite scale - his Swiss Army Pen Knife.  Always a scout at heart!
