Why are more and more highways using UHPC precast drainage channels? Before clarifying this issue, let’s first take a look at why drainage channels are used.

During the construction and lifting of highways, there may be insufficient longitudinal and transverse slopes or local depressions in the drainage of certain sections, which can lead to delayed drainage or long-term water accumulation on the road surface during the rainy season, thereby affecting driving safety and road durability.

For local water accumulation on the road surface, traditional treatment methods often include setting up blind drainage ditches, milling and repaving the road surface, or adding and leveling it, which often result in high treatment costs, significant interference with driving, and inconsistent appearance of the road surface after completion.
