Abstract: Provided herein are roadways containing polyurethane materials. A roadway includes a base layer of a compacted in situ material and/or a wear layer disposed on the base layer. One or both of these layers may include the polyurethane material to bind other components in the layers and to form more robust and durable roadway structures capable of withstanding operating loads of the roadway. In some embodiments, the polyurethane material is added to the wear layer by mixing in situ soil and/or foreign aggregate with polyurethane material or by dispensing the polyurethane material over the existing partially formed wear layer. The base layer may or may not include a polyurethane material. The type, concentration, distribution, and processing of the polyurethane material in the wear layer may be the same or different than that in the base layer.

Abstract: Provided are adhesive materials for fire resistant applications, methods of using these adhesive materials on lignocellulosic and other like substrates, and composite materials including lignocellulosic substrates and these adhesive materials. In addition to being fire-resistant, the composites formed from the substrates and adhesive materials may be also durable to moisture. The adhesive materials may include at least one proteinaceous-containing material and at least one magnesium oxychloride material. Other materials may be present as well, in some embodiments. For example, an adhesive material may include a solvent or a vinyl polymer. In some embodiments, water may be used as a solvent and the adhesive material may be referred to as an aqueous adhesive material. Some examples of suitable vinyl polymers include but are not limited to polyvinyl alcohol (PVOH), polyvinyl acetate (PVAc) and vinyl acetate/ethylene (VAE).
