Betonipäällysteiden

Betonipäällysteiden refers to concrete pavements, a common and durable surface for roads, airports, and other infrastructure. These pavements are constructed using a mixture of cement, aggregates (such as sand and gravel), and water, which hardens over time to form a rigid surface. The primary advantage of concrete pavements is their exceptional strength and longevity, often outlasting asphalt surfaces significantly. They are also resistant to deformation under heavy loads and can withstand extreme temperature variations.

The construction process involves preparing the subgrade, followed by placing and compacting the concrete. Joints are typically incorporated into the pavement design to control cracking caused by temperature changes and shrinkage. These joints can be sawed, formed, or grooved. Maintenance for concrete pavements generally involves sealing joints and repairing any spalling or cracking that may occur. While the initial cost of concrete pavement can be higher than asphalt, its extended service life and lower maintenance requirements often make it more economical over the long term. Its light color can also contribute to reduced heat island effects and improved nighttime visibility.
