Kivimurskepäällysteet

Kivimurskepäällysteet, often referred to as gravel pavements or crushed stone surfaces, are a common type of road construction material. They consist of a compacted layer of crushed rock aggregates. The size and type of aggregate used can vary depending on the intended application, such as low-traffic country roads, walking paths, or as a base layer for more durable pavements like asphalt or concrete.

The primary components of kivimurskepäällysteet are crushed stone fragments that are angular and interlocking. This angularity is crucial for achieving good compaction and stability. The material is typically spread in layers and then compacted using heavy machinery. The grading of the aggregate, meaning the distribution of different particle sizes, plays a significant role in the pavement's performance. A well-graded mixture allows for denser packing, resulting in a stronger and more durable surface.

Kivimurskepäällysteet offer several advantages, including relatively low construction costs and ease of maintenance. They are permeable, allowing water to drain through, which can be beneficial in certain environments. However, they are also prone to wear and tear, dust generation, and can become uneven over time, requiring periodic grading and replenishment. Despite these limitations, their cost-effectiveness and simplicity make them a practical choice for many applications where high-performance surfacing is not a primary requirement.
