Quality and demand drive our asphalt production. We customize any grade asphalt mix, from the standard G2 mix to a polymer modified high-performance mix, the P-401 airport mix - exactly what you order, every time you order. And we take responsibility for our environment. An innovative baghouse limits emissions to less than half of South Dakota and federal standards.   Hot Mix   Cold Patching Material SD DOT Class G   UPM High Performance Mix - Madison Street Plant - Rice Street Plant - Yankton Plant   - Madison Street Plant       SD DOT Class D E   Cold Mix Asphalt - Yankton Plant   - Madison Street Plant - Yankton Plant
