A static compactor is a heavy machine used in construction and waste management to compress materials like soil, asphalt, or waste. It operates by applying a steady weight or pressure to the surface, which helps to reduce the volume of the material and increase its density. This process is essential for creating stable foundations or preparing surfaces for further construction. Static compactors come in various sizes and designs, often featuring a flat or smooth drum that rolls over the material. They are commonly used in road construction, landfills, and site preparation to ensure that the ground is solid and well-compacted before building or paving begins.
