Program Topics:

This one-day two section course includes a section on the use of recycled tire crumb rubber in asphalt mixes and a section on the use of tire derived aggregate in road construction and maintenance projects.

Rubber Asphalt Pavements (RAP) - This session covers how recycled tire rubber is used to modify asphalt, how to get rubber into asphalt, and offers engineers and contractors a clear set of data on how it works. It provides information on how rubber can be designed into asphalt mixes. The field performance of several projects in a range of environments using a range of mix designs is discussed. Key topics include new methodology and tests to measure rubber, production and design economics, full depth and overlay applications, examples of rubber as part of a pavement management system, and lifecycle cost assessments of rubber pavements.

Rubber Asphalt Pavements:

  • Resistant to rutting and cracking
  • Improves pavement flexibility
  • Slows surface oxidation
  • Produces a more sustainable pavement

Tire Derived Aggregate (TDA) - This session covers the benefits of tire derived aggregate in road construction and maintenance for local transportation agencies. It discusses TDA use in storm water infiltration galleries, steep hill road repairs, gabion baskets, pile wall, rock wall and retaining wall construction, unpaved shoulders, erosion control, pothole repair, cyclical wetting, Humboldt State University research, and how to partner with project planners, designers and TDA suppliers.

Tire Derived Aggregate:

  • Lightweight and free draining
  • Has low earth pressure and are good insulators
  • Compressible and dampens vibrations
  • Inexpensive and durable

Panel of Instructors:

Rubber Asphalt Pavements Training:

Dr. Redmond (Red) Clark is president of Asphalt Plus, a company working to expand the cost-efficient use of recycled tire rubber in asphalt. He is also the chairman of CBL Industrial Services, a group of companies providing manufactured chemistries, technical support and heavy equipment for industrial applications. Red has a PhD in the environmental sciences. During a 40-year career, he has served as a university professor, a consulting engineer, director of a state environmental management program, and president/director of both national and global manufacturing and service companies.

James Meister is a research engineer in the Civil and Environmental Engineering Department at the University of Missouri-Columbia. He currently serves as senior research assistant responsible for testing equipment in the Missouri Asphalt Pavement and Innovation Laboratory. His work includes research and analysis of sustainable pavement materials including ground tire rubber.

Punyaslok Rath is a PhD graduate research assistant to Dr. William Buttlar, Chair, Flexible Pavements, Department of Civil and Environmental Engineering at the University of Missouri-Columbia. Mr. Rath’s research focus is on the use of ground tire rubber in pavements, simple performance tests for asphalt mixtures, thermal cracking research and smart pavements.

Tire Derived Aggregate Training:

Monte Niemi is CEO/Founder of First State Tire Recycling. He started in 1981 with a vision of environmentally sustainable methods of converting scrap tires into valuable civil engineering tools. More than 60 million discarded tires later, he and his team at First State Tire Recycling, and its subsidiary I Do TDA Manufacturing have placed their patented Recycled Tire Engineered Aggregate (R-TEA) in more than 220 civil engineering projects.

Joaquin Wright is a Senior Project Manager and TDA specialist for GHD inc. He has worked actively with Tire Derived Aggregate since 2000 and has managed numerous TDA research projects, pilot studies, TDA projects and outreach efforts funded by California Department of Resources Recycling and Recovery (CalRecycle). He has a BS in Environmental Resource Engineering from Humboldt State University, and is currently an adjunct professor at the University. He is a Sustainability Professional credentialed as a “train the trainer” with the Institute for Sustainable Infrastructure. His experience with TDA use is extensive and ranges from slope and road repair to material property research.
