Bridge Engineering Blog & Technical Insights

Our country's highways are developing rapidly, and many new and renovated highways have been built and rebuilt in recent years, which are basically adoptedasphalt pavementAt present, more than 95% of highways are asphalt pavement.

Expansion jointsIt is set up in the process of building construction considering the thermal expansion and contraction caused by the change of temperature, and the building that is too long or too wide will crack due to expansion and contraction, resulting in the destruction of the building. Therefore, during the construction process, the building will be divided into several parts to ensure the expansion and contraction of each section and avoid cracking. There will be a number of problems in the process of expansion joint treatment, such as untimely treatment, expansion joint leakage, thus affecting the quality of the whole project, so expansion joint as a key part of the construction of large buildings, it is of great significance to do a good job in waterproof engineering.

I don't know how to design engineering costs, but I have a lot of contact with drawings. Not to mention silence, durability and friction. Just talk about my understanding from the drawings, concrete pavement needs expansion joints, asphalt pavement becauseDuctilityIt's better. So there is no need for expansion joints. You can think about it. On the highway, the car kept pressing overexpansion joints feeling.

The United States produces about 300 million per year Waste tires How to deal with it is a big problem!

Some tires are refurbished by small workshops, polished and carved patterns, and the new products continue to be sold, but this behavior hides a crisis.

Before the official start of construction, while ensuring that the municipal road and bridge project obtains the relevant construction permit, it is also necessary to do a good job in the construction report to ensure that the project construction has complete conditions for starting.
