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.
E01C 19/00 - Machines, tools, or auxiliary devices for preparing or distributing paving materials, for working the placed materials, or for forming, consolidating, or finishing the paving
E01C 19/05 - Crushing, pulverising, or disintegrating apparatusAggregate screening, cleaning, or heating apparatus
E01C 19/45 - Portable apparatus for preparing, or for preparing and applying to the road, compound liquid binders, e.g. emulsified bitumen, fluxed asphalt
E01C 19/48 - Machines, tools, or auxiliary devices for preparing or distributing paving materials, for working the placed materials, or for forming, consolidating, or finishing the paving for laying-down the materials and consolidating them, or finishing the surface
E02D 3/12 - Consolidating by placing solidifying or pore-filling substances in the soil
E01C 7/30 - Coherent pavings made in situ made of road-metal and binders of road-metal and other binders, e.g. synthetic material
E01C 7/36 - Coherent pavings made in situ by subjecting soil to stabilisation
