by Many road constructions in our country are carried out in environments with high altitude, low temperature, and alternating dry wet cycles, coupled with the long-term role of modern transportation vehicles.
Concrete, as an important part of highway construction, is prone to cracking in this environment, especially when the foundation sinks and the road surface is crushed, the width and depth of cracks will further expand, seriously affecting the comfort and safety of traffic, and posing a huge threat to people’s lives and property.
Therefore, it is particularly important to study the changes in concrete performance after concrete cracks occur.
