On October 23, 2018, BioMAG\u2122 entered full-scale accelerated pavement testing on Section W10 at the National Center for Asphalt Technology Test Track in Alabama. The 12.5-mm surface mixture contained 20% reclaimed asphalt pavement<\/strong> and a soybean-based biopolymer-modified binder.<\/p>\n

BioMAG\u2122 combines 50% SIP-1111\u2122 rejuvenator<\/strong> with 50% biopolymer<\/strong>. W10 put that dual-function formulation into an instrumented track section exposed to accelerated heavy-truck traffic, creating a direct field record of cracking, rutting, texture, and long-term pavement condition.<\/p>\n

Field performance at 5 million ESALs<\/h2>\n

At 5 million equivalent single axle loads, the W10 section recorded no cracking<\/strong>, 2.5 mm of rutting<\/strong>, and 0.8 mm mean texture depth<\/strong>. The two 20% RAP control sections also recorded no cracking, with approximately 0.2 mm and 0.5 mm of rutting and mean texture depths of 0.6 mm and 0.7 mm.<\/p>\n

A 20-million-ESAL pavement record<\/h2>\n

NCAT continued trafficking W10 after the first-year evaluation. A later NCAT field paper describes the seven-year-old section as having accumulated approximately 20 million ESALs with minimal surface distress<\/strong> before a separate spray-on pavement-preservation study began in 2024.<\/p>\n

That pre-treatment condition extends the original construction story from an early demonstration to a long-running accelerated pavement section. The 2024 surface treatments created a new research phase; the approximately 20-million-ESAL condition documents W10 before those treatments were applied.<\/p>\n

What W10 demonstrates for asphalt teams<\/h2>\n

W10 connects three priorities in one field section: recycled asphalt use, polymer-modified binder performance, and long-duration trafficking. BioMAG\u2122 brought SIP-1111\u2122 rejuvenation chemistry and soybean-based polymer into the same formulation, while NCAT measured pavement response over millions of heavy-truck load repetitions.<\/p>\n

For producers and agencies evaluating recycled-content or polymer-modified mixtures, W10 provides a full-scale reference point: 20% RAP, no cracking at 5 million ESALs, and minimal surface distress after approximately 20 million ESALs<\/strong>.<\/p>\n

Lower rut depth is favorable; texture depth is descriptive. Control values are approximate as reported.<\/p>\n
