The Actual Stage of Research in the Field of Measures to Reduce the Sensitivity at the Moisture of the Patent Literature

摘要

Inventions in the field of reducing the moistening sensitivity of road trips address a theme related to the evolution of technology . Of particular importance is the impermeability of the road layer. An invention (Iorgoiu & Velcea, 2011) refers to a composition for pavement roads . The invention described above refers to another invention of a porous concrete road surface made of polymer modified cement (Zhijian, 2009). The stability of the road slopes is important for reducing the moistening sensitivity of the embankments, by supporting walls. The following described invention (Popescu, 2000) refers to a support wall of prefabricated elements which also combines the prefabricated elements recovered. Of particular importance in reducing moisture sensitivity are drainage technologies. An invention (Strunga, 1994) refers to the drainage screen for roads that collects, transports and discharges infiltrated water from the moorings and from the active area of the roads.
