Latest Patents

Yamada holds a patent for a NOx removing pavement structure. This invention features a concrete base layer, a paving layer, and a surface layer designed to effectively clean nitrogen oxides from the environment. The surface layer consists of 100 parts by weight of cement, 5-50 parts by weight of titanium oxide powder, and 100-700 parts by weight of aggregate. This unique composition provides the surface layer with NOx-cleaning capabilities and excellent durability. Additionally, pozzolan materials, particularly blast furnace slag, or adsorbing materials can be incorporated into the surface layer. The paving layer can be made of either asphalt or concrete, with the asphalt paving being porous and featuring an uneven surface. The thickness of the surface layer is ideally between 1-300 mm for concrete paving and 2-15 mm for asphalt paving.
