Analysis of defects and repair methods of components of road-building machines operating in contact with humid environments

Defects of components of road-building machines operating in a humid environment and in a contact with different liquids have been analyzed. It is found out that the main defects of the components operating in a humid environment are corrosion, cracks in body components, blowholes and malfunction of hole geometry. Traditional methods for removal of the defects, as well as the possibility of the use of polymer composites materials for repair of components of road-building machines operating in a humid environment are described.
