Aszfaltnedvesség

Aszfaltnedvesség refers to the presence of moisture within or beneath an asphalt pavement layer. This moisture can originate from various sources, including rainwater infiltration, groundwater seepage, or trapped construction moisture. The impact of aszfaltnedvesség can be significant, leading to a deterioration of the pavement's structural integrity.

When water penetrates the asphalt mix, it can weaken the asphalt binder, which is the glue holding the aggregate materials together. This weakening reduces the pavement's load-bearing capacity and makes it more susceptible to deformation under traffic. Furthermore, aszfaltnedvesség can contribute to freeze-thaw damage. In colder climates, water trapped within the pavement can freeze, expand, and create small cracks. Repeated freeze-thaw cycles exacerbate these cracks, leading to potholes and other surface defects.

Beneath the asphalt layer, moisture can affect the underlying base and subbase materials. This can lead to a loss of support for the pavement, causing settlements and unevenness. In some cases, water trapped beneath the asphalt can create hydrostatic pressure, further compromising the pavement's structure. Identifying and mitigating aszfaltnedvesség is crucial for extending the lifespan of asphalt pavements and ensuring road safety. This often involves proper drainage design, crack sealing, and, in severe cases, reconstruction.
