Awards issued prior to january 20, 2025, were funded under previous administrations and may not reflect the priorities and policies of the current administration.** soylei innovations (SLI), a limited liability company registered in the state of iowa operating a bioproducts research facility at the iowa state university (ISU) research park, will scale three related bioproducts for use in the asphalt construction industry derived from poly(acrylated epoxidized high oleic soybean oil) (paehoso), an agricultural commodity-based thermoplastic:P1: biomag™-easypave, a paehoso emulsion applied to 100% reclaimed asphalt pavement (RAP) millings to facilitate the construction of new asphalt pavements without the need for heat or virgin raw materials at a drastically reduced cost compared to hot mix asphalt (HMA) or concrete. Such cold recycled pavements will reduce the proliferation of RAP waste piles while improving transportation infrastructure, especially in historically underserved low-income rural and urban communities.P2: biomag™-FOG'n'fix, a rejuvenating and sealing paehoso emulsion applied to existing asphalt pavement surfaces to extend their service life. Unlike incumbent asphalt emulsion products, biomag™-FOG'n'fix will minimize traffic disruption with rapid penetration into the pavement pore structure, preserving traffic markings and skid resistance on the pavement surface.P3: biomag™-easypmac, a rejuvenating polymer modifier for high-traffic HMA pavements with high RAP content for reductions in cost, waste, energy usage, and emissions generation. Incumbent SBS-modified asphalt must be produced at specialized asphalt terminals and interacts poorly with RAP. Conversely, this bioproduct and be added at the asphalt plant, freeing contractors to formulate HMA that saves cost and increases RAP utilization.SLI will scale up: a chain transfer agent (CTA), an ingredient in paehoso manufacturing (40KG, P1-3); biomag™-glytex, a paehoso-based surfactant that stabilizes biomag™ emulsions with micron-scale particle size (1000 KG, P1-2); and polymer compounding required to transform paehoso to a granular state (5000 KG, P3). Collaborator CHS INC will supply epoxidized soybean oil feedstocks(up to 100 ton/d), and ACS technical products will develop the capacity to make up to 30 ton/d paehoso using CHS/ SLI inputs. SLI and ISU will optimize biomag™ product formulations; ncat and ISU will conduct tea and LCA analyses of the bioproducts. SLI and colorbiotics (CB) will collaborate to upgrade paehoso to finished emulsions (100 tons each). SLI, CB, and ncat will collaborate with stakeholders to demonstrate the products in pilot construction/maintenance projects, make head-to-head comparisons with incumbent products, and develop verified environmental product declarations. SLI and ncat will evaluate treated pavement lifetimes through accelerated wear tests. These activities will advance the development of cost-competitive bioproducts with environmental benefits compared to incumbent products, aligned with the 10 bioproduct pilot program priorities.
