What equipment is used to finish the surface of compacted materials for crushed stone bases and sub-bases?

The use of blading or automated equipment to finish the surface of compacted materials for crushed stone bases and sub-bases is essential due to its ability to create a smooth and even surface. This type of equipment is designed to level the material efficiently, ensuring proper grading and compaction, which are crucial for the stability and longevity of the pavement structure. Automated blading can adjust to varying contours and can complete the finishing process with precision, leading to a uniform thickness and proper drainage characteristics.

While other equipment like excavators, dump trucks, and pavers have specific roles in the construction process, they do not specialize in the finishing aspect of compacted materials. Excavators are primarily for digging and moving material, dump trucks are designed for transporting materials, and pavers are used for laying asphalt rather than finishing the sub-base. Hence, blading or automated equipment is specifically suited for achieving the desired finish on the surface.
