Investigation and testing needs: existence of polluted water; problems caused by microorganisms; impact of biodiversity, etc.; corrective strategies; applications of biodeterioration in the creation of new green materials; model development for biodiversity processes. The general objectives of biodeterioration testing are: assessment of the impact of biodeterioration on weight loss, porosity and compressive strength under environmental control; and analysis of the relationship between these three properties and environmental conditions. 5.5 Planning Creating an effective plan for eliminating the effects and protection against biodeterioration (reconstruction and conservation, repairs, as well as monitoring in the maintenance phase) of bridges, special attention must be focused on the determination of analysis methods and identification of pathology. 6. Conclusion In addition to weight loss, biological damage can also affect other physical and mechanical damage material properties. The biogenic action produces a layer of high porosity, which leads to greater permeability and diffusion within the material. It is very important that the control of the biodeterioration process should begin with preventive measures in order to prevent the creation of conditions for the development of microflora. A good knowledge of environmental conditions, building materials and colonizing organisms enables the development of new technologies and safer and more effective conservation treatments. Historically, biodeterioration was previously treated with aggressive mechanical procedures that are not adequate for historical objects. During maintenance on historical bridges, it is necessary to use combined cleaning methods to remove biodeterioration according to the type and degree of colonization. Timely identification of the presence of biodeteioration with mapping and preventive measures make it possible to preserve the historical bridge and reduce the costs of expensive reconstruction and conservation. Currently, state of art, the most modern method with the application of the deep learning AI algorithm (a method inspired by the process that a person sees and processes in own brain) is based on the principle of moving pixels in the image through convolutional neural networks (CNN) and represents the first step in the development of this method (UNESCO).
