Brief Project Summary:
The soy-based dust suppressant developed at North Dakota State University was able to soften and rejuvenate aged asphalt. Recent trials have shown that a modified version can soften aged asphalt shingles to extend their lifespan. The goal of this research is to modify the existing formula and test on aged shingles. After months of exposure, the shingles will be tested to gauge the efficacy of the various treatments. The use of bio-based roof extenders has been going on for 15-20 years and applied through licensed contractors. Positive research results will enable the roof rejuvenator product to contractors and retail outlets at a lower cost.

Information And Results
Project Summary

In previous testing, the soy-based dust suppressant developed at NDSU was able to soften and rejuvenate aged asphalt. Recent trials with a roofing company have shown that a modified version can also soften aged asphalt shingles increasing their repairability and extending the lifespan of existing roofing. The goal of the proposed research is to modify the existing formula and test several variations on aged shingles. The formulas will be made at NDSU and tested on an outdoor fixture of aged shingles located on the NDSU campus. After months of exposure, the shingles will be removed and subjected to lab tests to gauge the efficacy of the various treatments. The optimal formula will be down selected, produced, marketed and sold by BioBlend LLC in parallel to the existing dust control products. The use of bio-based roof extenders has been going on for 15-20 years at a cost to the homeowner of $1,500 - $2,000. These treatments are applied through a network of licensed contractors. Our plan will be to offer our roof rejuvenator to roofing companies and do-it-yourselfers at a much lower cost. The material will be available for purchase on-line or local hardware store in a form that can be applied with a common yard sprayer. There are more than 112 million homes in the US with asphalt roofs with the average roof requiring 4-5 pails of ready to apply material. Ifjust 2% of these homes are treated, the amount of soybean oil would equate to 11 million bushels.

Project Objectives

Objectives:
o Synthesize at least 20 variations of our soy-based dust suppressant for asphalt shingle treatment.
o Test these formulas on aged shingles outdoors for 10 months.
o Down select the optimal formula.
o Transfer the formula and know-how to our existing partner, BioBlend Renewables LLC for production and sales.

Project Deliverables

o Midterm and final reports
o Test results and marketing plan. The exact formula will be kept as a trade secret

Benefit To Soybean Farmers

The primary benefit to ND soybean farmers will be to expand the market for products derived from soybean oil thereby, increasing the demand for soybeans.
The secondary benefit will be to provide a product that farmers can use themselves to extend the life of their existing asphalt shingled roofs.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
