Brown Bag: Overview & Applications of Tire Derived Aggregate
This one-hour course will provide participants with an overview of the use and application of TDA's high value, lightweight aggregate product manufactured from discarded end-of-life tires. Recycled tires are shredded into irregular shapes and sizes from 2 inches to 10 inches in size, and is called “Tire Derived Aggregate”, or TDA for short. This sustainable value-added aggregate product provides environmental, economic and performance benefits to a variety of civil engineering projects, and when installed properly is safe, LEED Certifiable, and approved as a standing beneficial use aggregate by the MPCA. (Minn. Administrative Rule 7035.2860 subd. G & H).
Monte Niemi, Founder and Owner of First State Tire and TDA Manufacturing, will present the 10 Beneficial Properties of TDA, and how these properties are applicable to solving a variety of problems encountered in various civil engineering projects:
- Shear Strength
- Capillary Break
- Reduced Lateral Loading
- Void Space
- Filtration Factor
- Vibration Mitigation
Speaker: Monte Niemi was the first to recognize the value of TDA and its uses in Civil Engineering applications starting in 1984, and since that time he has introduced Multiple Beneficial applications for TDA and its Ten engineering properties. Minnesota's design and construction community has experience in over 350 installations of TDA creating site improvement. Best Management Practices (BMP's) for TDA were introduced and updated as understanding of how valuable this material is, in so many diverse applications.
Early in his career at First State Tire, Monte received patents for his TDA designs and applications of this recycled tire material. In 2012 he helped introduce TDA Mfg. a lightweight aggregate manufacturing facility. and in 2018 he helped Introduced I Do TDA International Distributors of Tire Derived Aggregate, which is now available nation wide to help connect Engineering Firms and the TDA aggregate manufactures. With 35 years of TDA project case histories the future looks promising.
