Many people may say when they see spraying waterproof coating, spraying coating is very simple and does not require any explanation at all. But is it really so?
Bridge deck waterproofing construction is mainly divided into two parts: bridge deck cleaning and bridge deck waterproofing coating spraying.

Many people have never heard of the trenchless trench gunning repair technology because its name is too long and somewhat convoluted, but its international reputation is extraordinary. The U.S. Highway Strategic Research Program calls it the most durable. and efficient repair methods.

With the rapid development of my country's national economy, the traffic volume is also increasing day by day, which makes highway construction face severe tests, which raises new topics for the maintenance and management of asphalt pavement. The quality of asphalt concrete and its paving can directly affect the quality of the road surface. This article mainly takes the LB-2000 asphalt mixing plant as an example, starting with its working principle, and analyzes the causes of failures in the asphalt mixing plant in detail, further discusses the specific preventive measures, and proposes relevant preventive measures in order to Provide an effective theoretical basis for the normal operation of asphalt mixing plants.

The need to add water to the slurry seal has basically become common knowledge in road maintenance. But many people don’t understand why water is added to it.
Why is water added to the slurry seal? Water in the slurry seal layer is an important component of the slurry mixture, and its amount determines the consistency and compactness of the slurry mixture to a certain extent.

Synchronized gravel sealing is already a common method of road maintenance, and everyone is aware of the precautions during the construction process. But few people know what to pay attention to after the construction is completed. Let’s talk about this topic today.
