In the construction of road and bridge engineering, strengthening the construction technology of the waterproof layer is not only one of the important ways to ensure the quality of the road and bridge engineering, but also one of the important means to prevent the occurrence of road and bridge safety accidents, so as to achieve the final quality standard and long service li.
The importance of road and bridge protection
In the past 20 years, many concrete bridge decks in Europe and North America have been damaged to varying degrees due to water leakage, and bridge decks with waterproof layers have no obvious damage as long as there is no large-scale dama.
The waterproof system is composed of coordinated and matched waterproof layers (bonding layer, buffer layer) and pavement lower layer, which play the role of waterproof isolati.

Performance upgrade
The reasons for bridge deck damage/leakage are carefully studied: design problems, material quality, construction technology and management, e.
refuse to follow suit
The launch of new products in every industry is a good opportunity for "upper position", because it is new enough, so it is necessary to dig deep into the research and development of self-waterproof coatings for bridge deck structur.
