Section 3 Scenarios

We would first need to know the critical to quality requirements of the manufacturer’s customer and application for the asphaltic roofing product and coating products. We would make sure we asked the appropriate questions to qualify the manufacturer. We would need to know which coating products they manufacturer and its use. We would need to understand what percent of tire rubber would be acceptable without negatively changing the compound mix for each product. We would need to understand what the environmental requirements with the requirements to be green and environmentally friendly. We would want to know how and why they would offer a 50-year warranty. We would communicate with ABC Roofing that we have assisted other roofing companies who have seen real benefits in terms of reduced costs and enhanced product performance, including greater longevity, durability, enhanced flexibility, metal adhesion, ease of installation, rainwater management, porous, heat resistant, high abrasion, resistant to wear and tear and low UV degradation. Some unique considerations related to using crumb rubber in roofing and coating products include: • Whether the product is intended for new or repair roofs; • What materials and performance standards are the manufacturer’s competition obtaining? • Is the product mixed with other materials, such as glass, plastic, bonding materials or others? • Is adhesion required, and to what standard? • Odor may be a challenge in some applications and processes. Depending on the product requirements, it would make most sense to begin by testing using 50 mesh material based on the knowledge of use of material in some asphaltic roofing products. Some coating products may need 50 – 80 mesh. In California we have not found the demand yet for 80 mesh material for manufacturers. 30 mesh tire material is used as a filler material and in some cases the rough edges may help to produce voids that may be needed. 30 mesh material is not always available so I would recommend addressing if alternative sizes could be used instead. ABC Roofing most likely has their own lab but if they did not then we would provide technical assistance in the way of a compounder and testing support for the 8 products. We would first classify the rubber as per ASTM Standard D5603 (Classify the Source of Rubber) and verify the particle size the company is currently using as per ASTM D5644. Roofing requires many tests be performed including ASTM D7158 Class H, ASTM D3161 Class F, ASTM E108 Class A Fire Rating, ICC Approval-ESR-3150, ASTM D3462, ASTM D3018 Type 1 and UL 2218 Class 3. Based on our experience, for asphaltic roofing products the following two ASTM tests would be a requirement, in addition to others: ASTM D6164, Physical Properties Specification for SBS Membranes with Polyester and Glass/Fiber; and ASTM D6162, Physical Properties Specifications for SBS Membranes Polyester.

For coatings, we believe these would be among the many priority tests to consider: • ASTM D968, Abrasion Resistance Test; • ASTM C1028, Coefficient of Friction; and • ASTM C297/C297M, Adhesion Test.

As detailed in our cost proposal, the two roofing tests will cost approximately D6161 and ASTM D6182 will cost $3,900 each, while the coating costs are in the $1,000 range. There may be other tests that will be required for each product because we have not looked at the regulatory and certification requirements previously because the roofing companies invested heavily in developing the roofing products. If we assume that ABC Roofing will add the tests for the shingles, it would be an estimated
